When you surf the web it is possible to learn information about you even when you don't want to advertise who you are. This is true even if your system contains no virus or malware software. Specifically information that is easily available online includes your IP address, your country (and often more location information based on IP address), what computer system you are on, what browser you use, your browser history, and other information. It gets worse. People can get your computer's name and even find out your name if your machine supports programs like finger or identd. Also, cookies can track your habits as you move from machine to machine.
How do people get this basic information about you?
When you visit another web site, information about you can be retrieved. Basically, information is intercepted and used by others to track your Internet activities.
How do you stop this from happening?
First of all, it is possible to serf the web anonymously and thereby stop leaving a trail for others to find. Note that this is not fool-proof, but it makes it much harder for people to know who you are. There are products called anonymous proxy servers that help protect you. The anonymous proxy server replaces your Internet address for its own. This has the effect of hiding your IP address and making it much harder for people to track you.
How do I get an anonymous proxy server?
There are many vendors who sell anonymous proxy servers. There are also free proxy servers available to you. Two such products are ShadowSurf and Guardster. Guardster (http://www.guardster.com/) offers various services for anonymous and secure access to the web, some paid as well as a free service. ShadowSurf (http://www.shadowsurf.com/) ShadowSurf provides anonymous surfing at their site for free. Go to it and you will find a box to enter a URL that you want no one to track. There are many others, but here are two that are frequently used.
Another interesting product, given the recent news about the Google search engine filtering its findings for the Chinese government, is Anonymizer (http://www.anonymizer.com). This company, among others, recently (Feb 1st, 2006) pressed that it "is developing a new anti-censorship solution that will enable Chinese citizens to safely access the entire Internet filter-free" (http://www.anonymizer.com/consumer/media/press_releases/02012006.html).
Does an anonymous proxy server make you 100% safe?
No. Still, you are much better off if you use such technology.
What other things should I be concerned about when trying to keep my private information private?
Three other items come to mind when trying to keep your information private. First, you can use an encrypted connection to hide your surfing. This article does not go into detail on this, but search the web and you will find a lot of information on this. Secondly, delete cookies after each session. Third, you can configure your browser to remove JavaScript, Java, and active content. This actually leads to limitations, so you need to think about the cost/benefit of this course of action.
Anything else?
Wishing you happy and safe surfing!

Phishing For Your Identity
Who hasn’t received an email directing them to visit a familiar website where they are being asked to update their personal information? The website needs you to verify or update your passwords, credit card numbers, social security number, or even your bank account number. You recognize the business name as one that you’ve conducted business with in the past. So, you click on the convenient “take me there” link and proceed to provide all the information they have requested. Unfortunately, you find out much later that the website is bogus. It was created with the sole intent to steal your personal information. You, my friend, have just been “phished”.
Phishing (pronounced as “fishing”) is defined as the act of sending an email to a recipient falsely claiming to have an established, legitimate business. The intent of the phisher is to scam the recipient into surrendering their private information, and ultimately steal your identity.
It is not at easy as you think to spot an email phishing for information. At first glance, the email may look like it is from a legitimate company. The "From" field of the e-mail may have the .com address of the company mentioned in the e-mail. The clickable link even appears to take you to the company's website, when in fact, it is a fake website built to replicate the legitimate site.
Many of these people are professional criminals. They have spent a lot of time in creating emails that look authentic. Users need to review all emails requesting personal information carefully. When reviewing your email remember that the "From Field" can be easily changed by the sender. While it may look like it is coming from a .com you do business with, looks can be deceiving. Also keep in mind that the phisher will go all out in trying to make their email look as legitimate as possible. They will even copy logos or images from the official site to use in their emails. Finally, they like to include a clickable link that the recipient can follow to conveniently update their information.
A great way to check the legitimacy of the link is to point at the link with your mouse. Then, look in the bottom left hand screen of your computer. The actual website address to which you are being directed will show up for you to view. It is a very quick and easy way to check if you are being directed to a legitimate site.
Finally, follow the golden rule. Never, ever, click the links within the text of the e-mail, and always delete the e-mail immediately. Once you have deleted the e-mail, empty the trash box in your e-mail accounts as well. If you are truly concerned that you are missing an important notice regarding one of your accounts, then type the full URL address of the website into your browser. At least then you can be confident that you are, in fact, being directed to the true and legitimate website.

Trojan Horse
Trojan Horse….Greek Myth or Computer Nemesis?
We have all heard the term Trojan Horse, but what exactly is it? A Trojan Horse is a destructive program that masquerades as a harmless application. Unlike viruses, Trojan Horses do not replicate themselves, but they can be just as destructive. One of the most dangerous examples of a Trojan is a program that promises to rid your computer of viruses but instead introduces viruses into your computer.
The Trojan can be tricky. Who hasn’t been online and had an advertisement pop up claiming to be able to rid your computer of some nasty virus? Or, even more frightening, you receive an email that claims to be alerting you to a new virus that can threaten your computer. The sender promises to quickly eradicate, or protect, your computer from viruses if you simply download their “free”, attached software into your computer. You may be skeptical but the software looks legitimate and the company sounds reputable. You proceed to take them up on their offer and download the software. In doing so, you have just potentially exposed yourself to a massive headache and your computer to a laundry list of ailments.
When a Trojan is activated, numerous things can happen. Some Trojans are more annoying than malicious. Some of the less annoying Trojans may choose to change your desktop settings or add silly desktop icons. The more serious Trojans can erase or overwrite data on your computer, corrupt files, spread other malware such as viruses, spy on the user of a computer and secretly report data like browsing habits to other people, log keystrokes to steal information such as passwords and credit card numbers, phish for bank account details (which can be used for criminal activities), and even install a backdoor into your computer system so that they can come and go as they please.
To increase your odds of not encountering a Trojan, follow these guidelines.
1. Remain diligent
Trojans can infect your computer through rogue websites, instant messaging, and emails with attachments. Do not download anything into your computer unless you are 100 percent sure of its sender or source.
2. Ensure that your operating system is always up-to-date. If you are running a Microsoft Windows operating system, this is essential.
3. Install reliable anti-virus software. It is also important that you download any updates frequently to catch all new Trojan Horses, viruses, and worms. Be sure that the anti-virus program that you choose can also scan e-mails and files downloaded through the internet.
4. Consider installing a firewall. A firewall is a system that prevents unauthorized use and access to your computer. A firewall is not going to eliminate your computer virus problems, but when used in conjunction with regular operating system updates and reliable anti-virus software, it can provide additional security and protection for your computer.
Nothing can guarantee the security of your computer 100 percent. However, you can continue to improve your computer's security and decrease the possibility of infection by consistently following these guidelines.

What are Intrusion Detection Systems
What are Intrusion Detection Systems?
Intrusion Detection System (IDS) are a necessary part of any strategy for enterprise security. What are Intrusion Detection systems? CERIAS, The Center for Education and Research in Information Assurance and Security, defines it this way:
"The purpose of an intrusion detection system (or IDS) is to detect unauthorized access or misuse of a computer system. Intrusion detection systems are kind of like burglar alarms for computers. They sound alarms and sometimes even take corrective action when an intruder or abuser is detected. Many different intrusion detection systems have been developed but the detection schemes generally fall into one of two categories, anomaly detection or misuse detection. Anomaly detectors look for behavior that deviates from normal system use. Misuse detectors look for behavior that matches a known attack scenario. A great deal of time and effort has been invested in intrusion detection, and this list provides links to many sites that discuss some of these efforts"(http://www.cerias.purdue.edu/about/history/coast_resources/intrusion_detection/)
There is a sub-category of intrusion detection systems called network intrusion detection systems (NIDS). These systems monitors packets on the network wire and looks for suspicious activity. Network intrusion detection systems can monitor many computers at a time over a network, while other intrusion detection systems may monitor only one.
Who is breaking into your system?
One common misconception of software hackers is that it is usually people outside your network who break into your systems and cause mayhem. The reality, especially for corporate workers, is that insiders can and usually do cause the majority of security breaches. Insiders often impersonate people with more privileges then themselves to gain access to sensitive information.
How do intruders break into your system?
The simplest and easiest way to break in is to let someone have physical access to a system. Despite the best of efforts, it is often impossible to stop someone once they have physical access to a machine. Also, if someone has an account on a system already, at a low permission level, another way to break in is to use tricks of the trade to be granted higher-level privileges through holes in your system. Finally, there are many ways to gain access to systems even if one is working remotely. Remote intrusion techniques have become harder and more complex to fight.
How does one stop intrusions?
There are several Freeware/shareware Intrusion Detection Systems as well as commercial intrusion detection systems.
Open Source Intrusion Detection Systems
Below are a few of the open source intrusion detection systems:
AIDE (http://sourceforge.net/projects/aide) Self-described as "AIDE (Advanced Intrusion Detection Environment) is a free replacement for Tripwire. It does the same things as the semi-free Tripwire and more. There are other free replacements available so why build a new one? All the other replacements do not achieve the level of Tripwire. And I wanted a program that would exceed the limitations of Tripwire."
File System Saint (http://sourceforge.net/projects/fss) - Self-described as, "File System Saint is a lightweight host-based intrusion detection system with primary focus on speed and ease of use."
Snort (www.snort.org) Self-described as "Snort® is an open source network intrusion prevention and detection system utilizing a rule-driven language, which combines the benefits of signature, protocol and anomaly based inspection methods. With millions of downloads to date, Snort is the most widely deployed intrusion detection and prevention technology worldwide and has become the de facto standard for the industry."
Intrusion Detection System (IDS) are a necessary part of any strategy for enterprise security. What are Intrusion Detection systems? CERIAS, The Center for Education and Research in Information Assurance and Security, defines it this way:
"The purpose of an intrusion detection system (or IDS) is to detect unauthorized access or misuse of a computer system. Intrusion detection systems are kind of like burglar alarms for computers. They sound alarms and sometimes even take corrective action when an intruder or abuser is detected. Many different intrusion detection systems have been developed but the detection schemes generally fall into one of two categories, anomaly detection or misuse detection. Anomaly detectors look for behavior that deviates from normal system use. Misuse detectors look for behavior that matches a known attack scenario. A great deal of time and effort has been invested in intrusion detection, and this list provides links to many sites that discuss some of these efforts"(http://www.cerias.purdue.edu/about/history/coast_resources/intrusion_detection/)
There is a sub-category of intrusion detection systems called network intrusion detection systems (NIDS). These systems monitors packets on the network wire and looks for suspicious activity. Network intrusion detection systems can monitor many computers at a time over a network, while other intrusion detection systems may monitor only one.
Who is breaking into your system?
One common misconception of software hackers is that it is usually people outside your network who break into your systems and cause mayhem. The reality, especially for corporate workers, is that insiders can and usually do cause the majority of security breaches. Insiders often impersonate people with more privileges then themselves to gain access to sensitive information.

Protection You Can Afford
There are numerous ways you can lose the information on your computer. Your child decides to play Chopin on your keyboard, a power surge, lightening, a virus, or even simple equipment failure. Therefore, backing up the contents of your hard drive is an absolute MUST. By regularly making backup copies of your files and storing them in a separate location, you can typically get some, if not all, of your information back in the event your computer crashes.
While a regular backup to floppy, CD, or zip drive will save your files, wouldn’t it be great if you could create an exact copy (a drive image) of your hard disk? That means backups of all your files, programs, and user settings. This would definitely save you time when it came to reloading. Acronis may be able to help.
Acronis True Image is a robust disk-imaging utility software that copies the entire contents of your hard drive including data and operating system files, personalized settings, and more, onto another disk or disk partition. Its layout is easy to use and navigate. It also includes wizards which can walk you through both backing up and restoring your computer. Highlighted features include:
· Secure Zone — allows you to save data to a special hidden partition located on your hard drive which would eliminate the need to purchase an extra hard drive.
· PC Cloning — you can upgrade to a new system disk without needing to reinstall the operating system and applications, or configure user settings.
· Acronis Snap Restore - lightening-speed restore of your PC from an image. You can start working in seconds while your system is still being restored.

Make It Safe
New computers typically come with Microsoft Windows XP Service Pack 2, but they probably do not have the latest security updates. So when you first turn your machine on, leave it disconnected from your modem (cable or DSL) or your network router. Many systems come with a limited-time version of an antivirus program, usually McAfee Security Center or Symantec Internet Security. When you first run the system, the antivirus software will pop up a series of dialogs prompting you to activate the trial versions. Unless you have another security package ready to install, you should agree to switch on one of the trial versions, because you'll want to have security software running when you first connect to the Internet. (If you use one of the trial versions, you needn't feel obliged to buy an annual subscription when the trial runs out.) If you'd rather install other security software from a CD, do so now. When the software is fully installed (you'll probably need to reboot to complete the process), use the Start menu to open the Control Panel, then open the Security Center. Make sure that Firewall, Automatic Updates, and Virus Protection are all turned on. But don't connect to the Internet just yet.
Next insert a blank CD or DVD into the appropriate drive and then find and run the software on your system that lets you create a recovery disc, which will let you restore your system to its original state. Don't neglect this step: It's essential if rogue software or an overenthusiastic family member disrupts your system to the point where you need to return it to its out-of-the-box condition.
Now—and only now—plug in your network cable or connect to a wireless network. You don't need to turn off your machine before plugging in the cable. Windows should detect your network automatically. When you're connected, Windows' automatic updates service should start running automatically; notice the shield-like icon on the taskbar. If it doesn't start in a few minutes, run Windows Update from the Start menu. Also run any software-updating service that may be installed with your machine. On some systems, the updater will run automatically; others require you to launch a Software Installer or similarly named program. Either way, it's almost always wise to install any updates proposed by the updater.

10 Ways To Protect Your Laptop Against Theft & Loss
Laptop theft is rampant. You have a 1 in 10 chance your shiny new laptop will be stolen. And the real shocker: according to the FBI 97% are never recovered.
And they should know, the U.S. Department of Justice stated in a recent report that the FBI lost 160 laptops in a 44 month period ending in September of 2005. If FBI agents have trouble keeping track of their laptops, imagine what the ordinary person is facing.
The statistics are pretty grim. A laptop is stolen every 53 seconds. Ouch!
With stats like those you have to do everything in your power to avoid becoming a victim of laptop theft. If you keep valuable personal or business information on your laptop the consequences can be even more gruesome and devastating. For laptop hardware can be easily replaced, but your valuable information may be lost forever.
So here are...
10 Practical Ways to Protect Your Laptop Against Theft, Loss or Misplacement.
1. Keep Your Eyes On Your Laptop
Be aware of your laptop at all times especially when traveling. You wouldn't leave a Thousand Dollar Bill lying around unattended would you? So watch your laptop closely.
2. Don't Use An Obvious Laptop Bag
Carry your laptop in regular luggage that doesn't look like it has a laptop. Don't advertise your laptop to any would-be thieves.
3. Use Visual Locks And Restraints
Use visual locks and restraints to secure your laptop and to act as a deterrent. It won't fool hardened thieves but most will opt for a less secure laptop. For example, you can use a product like STOP, this system works by attaching a specially-made security plate to your laptop. This plate is barcoded and registered. It also carries a warning label letting would-be cyber thieves know that the ownership of your laptop is permanently monitored.
4. Use Passwords And Encryption
Use passwords and encryption to protect any sensitive information on your laptop. Again, unless you use very sophisticated encryption it won't fool the experienced hacker or hard-core digital thief but it will slow down and hinder the common criminal.
Set a BIOS Password for your laptop. You have to take advantage of any security option that's on your laptop's OS or operating system. For those using Mac OS X you can encrypt your entire hard drive and set-up a master password in order to view it.
Windows XP & Vista lets you encrypt files and folders. Just right click your data, select properties, open general tab and then advanced to check "Encrypt contents to secure data box".
5. Use Encryption Programs Like Steganos Safe 2007
You can also try something like Steganos Safe 2007. Vital files can be encrypted and it can even turn your USB thumb drive or iPod into a key for unlocking your hard drive.
6. Use Anti-Theft Software Like LoJack
Use anti-theft software that can track and locate your laptop or computer through the IP address once the stolen laptop is used to access the Internet. Use systems like "LoJack For Laptops". It costs Costs around 50 bucks a year but it may be worth that price for your peace of mind alone.
According to the info on their site they recover 3 out of 4 stolen laptops equipped with the LoJack system. It basically places hidden and silent software that reports back the IP address and location of the laptop once it is stolen and the thief connects to the Internet.
7. Use Invisible Ultraviolet Markings
Use invisible ultraviolet markings so that any recovered stolen laptops will be clearly marked as yours to the police. Keeping track of your laptop's serial number is also a good idea and have this number stored in a different place other than on your laptop.
8. Try Remote Data Deletion
If you place important information on your laptop have a remotely controlled self-destruct solution in place. Then your highly sensitive information can be deleted remotely after your laptop is stolen.
9. Be Prepared
Create company policies for management of your company's laptops. Have set procedures in place for tracking and reporting of any laptops stolen or misplaced. Be prepared for the inevitable.
10. Backup Backup Backup
Regularly backup any vital information you have on your laptop. Most information will be useless to potential thieves but may be extremely important to you personally or for the running of your business.
No matter if it is through theft or simple misplacement, losing a laptop is a painful experience, one you should avoid at all costs. However, if it does happen to you, be assured you can minimize the pain by having a complete backup of your laptop's contents. In most cases, this information will be much more valuable than the laptop itself.
For hardware can be easily replaced, your personal data and months/years of work may take forever to recover or redo. Sometimes it is lost forever, so BACKUP your information regularly. Keep your laptop and its contents safe and out of harm's way. Simply protect yourself and your laptop by using the tips you have just read.

Things to do for a healthy and secure PC
A Top 10 List That Can Save Your Computer
---------------------
Many who read this article may find these recommendations to be old news. However, think about the number family, friends, and associates that ask you for help fixing their PC and I believe you will understand why I chose to write this article..
This list of recommendations for a healthy & secure PC is by no means a complete list of everything you can and should do. It is however a great start if you want to keep your computer running properly for an acceptable period of time. It will also help prevent some of the most common issues related to PC security.
1. Hard Drive Fragmentation
---------------------
Believe it or not, many people have never even heard of hard drive fragmentation, or the process of Defragmentation. In a nutshell, when you install software or create files and data, the Operating System stores this data on your hard disk drive. The most efficient way of storing this data would be in one continuous disk file. However, files are not always stored this way, or are initially stored this way and later become split up, or fragmented. Because of this, when the data or file is retrieved, the hard drive must be searched in multiple places just to combine data that makes up one file. This slows things down tremendously. If you are running Windows 2000 or Windows XP, you should perform a disk defrag at least once every two weeks, more if possible. All of my systems run this process automatically once every week in the evening hours.
2. Installing Games & Disk Intensive Software
---------------------
If you're a gamer, or regularly use disk intensive software, the above Defragmentation process will help. However, you can also take another step to make things move a little faster. If you have two physically separate disk drives in your system, I suggest that you use one primarily for the Operating System and related software, and devote the other physical disk for installing games and other disk intensive applications. This cuts down on the competition for disk resources between your Operating System and other applications. There are other things you could do as well, such as configuring the appropriate type of RAID where multiple disks appear to the operating system as one big logical disk drive. This takes a little more planning to get the most out of your drives so I'll cover that in a future article.
3. Virus & Spyware Protection
---------------------
The bottom line here is; make sure you have installed some sort of anti-virus and spyware protection. Furthermore, don't just assume that the default configuration of the program is best suited for your environment. For instance, I can't tell you how many people I know whose computer has contracted a serious virus because of just one minor but very important task. When the anti-virus software pops up a message and tells you that your subscription is about to expire, don't just hit the ignore button. Take a five minute break from what you are doing and renew your virus signature subscription. Not only will this keep you up to date on newer viruses, it will allow your software package to update to newer versions. The same thing goes for spyware protection. There are plenty of free spyware protection solutions out there, none are perfect, but most do the job. I suggest using Microsoft's AntiSpyware Beta package at the least.
4. Software & Hardware Firewall Protection
---------------------
If you are not using a firewall, then you are just asking for trouble. Actually, there is a significant chance that your system is already compromised if you have no firewall protection at all. Many cable/DSL router combo devices have built in firewall protection, and this is at least a good start. However, if you have Windows XP SP2, go ahead and enable the built in firewall as it will provide you another level of protection. Oh, yes, and when the system pops up a message about whether or not to allow a certain application or communication to take place, don't just hit the ok button, read it thoroughly then make a decision.
5. Installing & Uninstalling Applications
---------------------
Just about every time you install a new application or piece of software you increase the time it takes to boot your PC and in some cases decrease its performance. On thing that drives me crazy is printing software. For the life of me I cannot understand how or why printer support software could total 400MB in size, but they sometimes do. Not only that, they tend to load all kinds of unnecessary real-time running applets. HP printers are notorious for this. Be very aware of what it is you are loading and only load those components that you need. Even some off-the-shelf software packages load adware and other not so helpful applets. Also, when you uninstall software, not all the software gets uninstalled in many cases. One thing I suggest is to purchase a registry cleaner. This can dramatically decrease boot times and in many cases increase the overall performance of your PC.
6. Purchasing & Downloading Items On The Internet
---------------------
When you download or purchase any software from the Internet, make sure you pay close attention to everything you are agreeing to or checking off on the various pages that lead up to the final purchase or download. As with everything else, make sure you read the fine print. You may be agreeing to download and install something you don't need or may impact the security and performance of you PC. Also, how many more mailing lists do you really need to be on? How many Internet Explorer tool bars do you need? Most of these tool bars should be renamed to "adware / spyware bars"
7. Installing Operating System & Application Patches
---------------------
In a nutshell, if you are using Windows XP, make sure that automatic updates are turned on. This is very important. Microsoft releases security and bug fixes routinely and some of them are critical in nature. Something people tend to overlook is updating and patching their applications. For instance, Microsoft Office has critical security patches and performance enhancements available in the form of patches and service packs. It's not just Operating System bugs that can put you at risk, applications can too.
8. Updating Drivers
---------------------
Similar to the above, hardware manufacturers routinely update their drivers. This includes video cards, sounds cards, capture cards, system boards, you name it. Some manufacturers have started to release automatic updates for their hardware, but many have not. Make sure you check these sites regularly and when a driver update is available, install it.
9. What Do Your Children Download
---------------------
This is a really big one. I can' tell you how may times I have been told by people that they have no idea how something got installed on their computer. Usually their second sentence contains "one of my children must have downloaded it". The first thing that comes to mind is "why do parents let kids download what ever they like in the first place". Not only can this severely impact the security and performance of your computer, who knows what your kids are getting their hands on. Do you know what one of the most frequently installed application installs I see on a teenagers machine is? Kazaa, BearShare, eDonkey, all P2P file sharing programs. I don't care what anyone says regarding how convenient and safe these applications are now, they are wrong. Monitor what your children are doing / downloading on the Internet. Install a parental control software package if need be.
10. Rebuilding Your Operating System
---------------------
If you are not familiar with system imaging software, I suggest you read up on them. One of the most popular packages is "ghost" and it's been around for quite some time. I rebuild my systems pretty much on an annual basis. When I first configured them, I used an imaging package to create a complete image of the basic OS and application install. This allows you to not only re-install the base operating system and applications by hitting just one button, but can save you big time in the event of a system disaster.
Conclusion
---------------------
Many of my peers and other technical people will read this and say it's all common sense and very basic. Well, if this is what you do for a living then yes, it is. But many people don't know these things or did know about them and have forgotten. So many PC are in such bad shape and it's beyond me how the average person even deals with it. It has to be frustrating not knowing where to turn or what to do, especially if you don't have a tech friend or family member to call on. I hate to sound pessimistic, but things are not getting better for the average home or small business person. Technology should not be this difficult to maintain. The average person just wants something that will work, and stay working.

Furthermore, don't just assume that the default configuration of the program is best suited for your environment. For instance, I can't tell you how many people I know whose computer has contracted a serious virus because of just one minor but very important task. When the anti-virus software pops up a message and tells you that your subscription is about to expire, don't just hit the ignore button. Take a five minute break from what you are doing and renew your virus signature subscription. Not only will this keep you up to date on newer viruses, it will allow your software package to update to newer versions. The same thing goes for spyware protection. There are plenty of free spyware protection solutions out there, none are perfect, but most do the job. I suggest using Microsoft's AntiSpyware Beta package at the least.
4. Software & Hardware Firewall Protection
---------------------
If you are not using a firewall, then you are just asking for trouble. Actually, there is a significant chance that your system is already compromised if you have no firewall protection at all. Many cable/DSL router combo devices have built in firewall protection, and this is at least a good start. However, if you have Windows XP SP2, go ahead and enable the built in firewall as it will provide you another level of protection. Oh, yes, and when the system pops up a message about whether or not to allow a certain application or communication to take place, don't just hit the ok button, read it thoroughly then make a decision.
5. Installing & Uninstalling Applications
---------------------
Just about every time you install a new application or piece of software you increase the time it takes to boot your PC and in some cases decrease its performance. On thing that drives me crazy is printing software. For the life of me I cannot understand how or why printer support software could total 400MB in size, but they sometimes do. Not only that, they tend to load all kinds of unnecessary real-time running applets. HP printers are notorious for this. Be very aware of what it is you are loading and only load those components that you need. Even some off-the-shelf software packages load adware and other not so helpful applets. Also, when you uninstall software, not all the software gets uninstalled in many cases. One thing I suggest is to purchase a registry cleaner. This can dramatically decrease boot times and in many cases increase the overall performance of your PC.
6. Purchasing & Downloading Items On The Internet
---------------------
When you download or purchase any software from the Internet, make sure you pay close attention to everything you are agreeing to or checking off on the various pages that lead up to the final purchase or download. As with everything else, make sure you read the fine print. You may be agreeing to download and install something you don't need or may impact the security and performance of you PC. Also, how many more mailing lists do you really need to be on? How many Internet Explorer tool bars do you need? Most of these tool bars should be renamed to "adware / spyware bars"
7. Installing Operating System & Application Patches
---------------------
In a nutshell, if you are using Windows XP, make sure that automatic updates are turned on. This is very important. Microsoft releases security and bug fixes routinely and some of them are critical in nature. Something people tend to overlook is updating and patching their applications. For instance, Microsoft Office has critical security patches and performance enhancements available in the form of patches and service packs. It's not just Operating System bugs that can put you at risk, applications can too.
8. Updating Drivers
---------------------
Similar to the above, hardware manufacturers routinely update their drivers. This includes video cards, sounds cards, capture cards, system boards, you name it. Some manufacturers have started to release automatic updates for their hardware, but many have not. Make sure you check these sites regularly and when a driver update is available, install it.
9. What Do Your Children Download
---------------------
This is a really big one. I can' tell you how may times I have been told by people that they have no idea how something got installed on their computer. Usually their second sentence contains "one of my children must have downloaded it". The first thing that comes to mind is "why do parents let kids download what ever they like in the first place". Not only can this severely impact the security and performance of your computer, who knows what your kids are getting their hands on. Do you know what one of the most frequently installed application installs I see on a teenagers machine is? Kazaa, BearShare, eDonkey, all P2P file sharing programs. I don't care what anyone says regarding how convenient and safe these applications are now, they are wrong. Monitor what your children are doing / downloading on the Internet. Install a parental control software package if need be.
10. Rebuilding Your Operating System
---------------------
If you are not familiar with system imaging software, I suggest you read up on them. One of the most popular packages is "ghost" and it's been around for quite some time. I rebuild my systems pretty much on an annual basis. When I first configured them, I used an imaging package to create a complete image of the basic OS and application install. This allows you to not only re-install the base operating system and applications by hitting just one button, but can save you big time in the event of a system disaster.
Conclusion
---------------------
Many of my peers and other technical people will read this and say it's all common sense and very basic. Well, if this is what you do for a living then yes, it is. But many people don't know these things or did know about them and have forgotten. So many PC are in such bad shape and it's beyond me how the average person even deals with it. It has to be frustrating not knowing where to turn or what to do, especially if you don't have a tech friend or family member to call on. I hate to sound pessimistic, but things are not getting better for the average home or small business person. Technology should not be this difficult to maintain. The average person just wants something that will work, and stay working.
