Knowing the basics of Adware and Spyware
People think that there is actually no difference between a spyware and an adware. Spyware is just a web term used to refer to an advertising supported software, which is otherwise known as adware. These are the pop-up ads that often come out whenever we open a website or download a shareware software. But according to some web experts, spyware is much much more.
Supporters of spyware and adware say that though it can be pretty annoying at times especially if you are really in a hurry, both do give consumers huge benefits. Because the product ads generate income for developers of shareware software, consumers can get them for free. Developers are in turn paid for their work. Of course, if you don’t want to be bothered by the constant pop-ups, you can always pay the licensing fee or the regular fee for the software. If you want it for free, you just have to sacrifice through the spyware.
There is however another downside to it. Spyware, from the name given to it, is actually used as a tracking device in your computer system. These tracking devices will look into your surfing habits, your chatting logs and even the number of times you open your email. If designed or programmed the right way, it can discover just about everything else in your system.
And because the program runs in the background, there is no way that a person can control the kind of information that he or she sends out.
These kinds of programs were actually originally used by parents or people in the business sector who wish to track down and put on record web activity. It is actually beneficial but not when people are not aware that they are being tracked down. This is often the case when people download software over the Internet. As mentioned before, it is used by companies to advertise their products and in turn help the developers of software keep their costs down so that they can afford to offer their programs for free.
Although privacy issues indeed come into play, there is nothing illegal about it. In fact, its use is prevalent all over the World Wide Web. There are however some areas that people who value their privacy will object to. Because of this, people are given the option to refuse the software.
There is really no way that one can avoid adware and spyware as these programs are packaged with the software that you will be downloading from the Internet. The most that you can do is to avoid downloading from the internet and to refuse any file downloads that you did not personally authorize. It is also good to only view websites that have a good reputation or those that have anti-spyware and adware programs installed in their pages.

Beware Spyware
Spyware and Adware are not only an ever increasing nuisance for computer users everywhere, but also a booming industry. According to Webroot Software, Inc., the distribution of online advertisements through spyware and adware has become a $2 billion industry.
The aggressive advertising and spying tactics demonstrated by some of these programs, require an equally aggressive response from a seasoned eradicator. Sunbelt Software is such a company. A leader in Anti-Spyware, Anti-Spam, Network Security and System Management tools, they gave consistently remained on the cutting-edge of anti-spyware programming since 1994.
One of their more notable software applications is CounterSpy 1.5. CounterSpy is designed to detect and remove spyware that is already in your computer system. Additionally, it provides real-time protection while preventing browser hijacking and changes to your computer’s Registry.
Other notable features include:
¨ Detection and Removal of Tracking Cookies – while it is true that applications like Microsoft AntiSpyware Beta are free, they do not include the ability to detect and remove tracking cookies like CounterSpy does.
¨ History Cleaner - erases any traceable trails left on your computer as you surf the Internet.
¨ Secure File Eraser - a powerful deletion tool that can completely eliminate all files you want removed from your computer including images, music, movies and applications.

Spam Buster
Spam. Nobody likes it. Nobody wants it. No, we aren’t talking about the canned meat, but those unsolicited, unwanted, irrelevant, or even inappropriate messages that hit our email in mass quantities. While most mailboxes have some type of spam filtering software built into their system, they never seem to do a very good job of catching what you want them to catch, and letting through what you want them to let through. Therefore, it becomes increasingly important to turn to some type of additional spam filtering product. One such filtering system, designed for Outlook and Outlook Express users, is receiving rave reviews for its superior detection and low rate of false positives (i.e,. what you want to get through does).
Cloudmark Desktop, formerly known as SpamNet and SafetyBar, uses a unique community-based filtering process. This community-based filtering system relies on users to report any new spam. Within minutes of a spammer being reported, they are placed on a blacklist. At that point, no other member will receive that particular spam. Cloudmark also applies the same basic process to phishing email scams.
What is interesting is how Cloudmark creates a digital reputation model of reporting spam. Each user starts with a neutral reputation. A user’s reputation will rise if they are among the first to identify undesirable content. On the flip side of the coin, a user’s reputation falls when they falsely reports spam. The result is a system that is automated, highly scalable and resistant to tampering.
An added bonus is that because the software doesn’t depend upon the user to configure its settings, it installs in minutes and is easy to use. Cloudmark blocks over 98% of spam from reaching your inbox and boasts over one million users worldwide.

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."

Beware Internet Explorer Plug-Ins
Just what is Intelligent Explorer? For your safety, you really need to know
I recently hit, by mistake, what I thought was an Explorer upgrade option. It turned out to be a pop-up appearing legitimate but really was not. It uploaded a product called Intelligent Explorer on my machine. What a nightmare!
I did some research on the web and found messages like this one from a BullGuard Antivirus Forum,
"PLEASE HELP!!! I HAVE A SPYWARE, TROJAN AND HIJACKER ON MY COMPUTER. I HAVE RUN BULLGUARD, CWSHREDDER AND AD-AWARE. ALL HAVE PICKED UP THE VIRUSES AND SAID THAT THEY HAVE BEEN MOVED/REMOVED BUT WHEN I LOG ONTO THE INTERNET THAT DAMN INTELLIGENT EXPLORER TOOLBAR IS SHOWING"
Another message from spywareinfo Forum goes something like this:
"Hey I'm having issues with something called Internet explorer toolbar - Intelligent explorer. I can’t find a way to remove it from my comp and I really don’t want to reinstall windows. I've used spybot, ad-ware, and cw shredder but nothing seems to work."
It appears that Intelligent Explorer allows other software to be downloaded to your machine and this is where the problem occurs. What is even more remarkable is that by downloading Intelligent Explorer, their license grants them the right to install software add-ins on your computer at their will. Take a look at what the software license for Intelligent Explore says (go to http://www.ieplugin.com/terms.html to read it all):
"You grant to us the right, exercisable by us until you uninstall the Software or this agreement is otherwise terminated, to provide to you the Service of downloading and causing to be displayed advertising material on your computer, through ‘pop-up’ or other display while you use your browser. You acknowledge and agree that installation of the Software may automatically modify toolbars and other settings of your browser. By installing the Software you agree to such modifications."
The company, IBC incorporated, is incorporated in Belize. I really can't believe this license!
One end user found highly objectionable pop-up advertisements generated by this software bundled with Intelligent Explorer in the form of extreme pornography.
I have yet to break this.
Intelligent Explorer is a plug-in, which can create a new home page, as well as start up and endless loop of pop-ups. You can remove the view bar, but then starting up Internet Explorer will cause it to reappear. I asked some friends to help, and no one could tell me what to do.
This is what I did:
I bought a copy of a program called XoftSpy and it removed the software. It took two scans and a reboot to do it. This is not an advertisement for this product. They advertised it was free, which it was to run, but then I had to buy it to actually fix anything. It cost me $40 and I am sure that there are freeware products out there as well, but that is what ended the nightmare for me. Other spyware products I have seen out there include spybot, NoAdware, Spyware Eliminator, Pal Spyware Remover, and Spyware C.O.P.
Let the buyer beware!

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.
