Trojan Horse .... Nemesis The Greek Myth Or PC?

We have all heard the term Trojan Horse, but what is it? A Trojan is a destructive program that masquerades as a harmless application. Unlike viruses, Trojans do not repeat themselves, but can be equally devastating. One of the most dangerous examples of a Trojan is a program that promises to rid your computer of viruses but instead introduces viruses to your computer.

The Trojan can be tricky. That has not been online and had a pop-up ads that claim to be able to rid your computer of some nasty virus? Or, even more frightening, you receive an email that claims to be warning of 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" software connected to your computer. You can be skeptical but the software looks legitimate and the company seems reputable. Proceeding to take their offer and download the software. In doing so, you have just potentially exposed yourself to a huge headache and your computer for a long list of ailments.

When a Trojan is activated, many things can happen. Some Trojans are more annoying than harmful. Some of the less annoying Trojans may choose to modify the desktop settings or add silly desktop icons. More serious Trojans can erase or replace the data on your computer, corrupt files, spread other malware such as viruses, spy on your computer and secretly report data like browsing habits to other people, log keystrokes to steal information such as passwords and credit cards, Phish for bank account details (which can be used for criminal activities), and also install a backdoor on the computer system so they can come and go as they wish.

How many spyware items are infecting your computer?

I just had, by mistake, a plug-in called Intelligent Explorer attach to my browser. What a nightmare! I have another article on this topic, but this brings home a point. Spyware or adware items are continually infecting computers. Most computers have no protection from them. Most frightening is the frequency of them. From the InfosecWriters web site, "According to a 2004 survey by America Online and the National Cyber Security Alliance, 91% of users questioned were familiar with the term spyware. Only 53% believed their computers were infected, but a scan found that 80% of their PCs had some type of spyware installed on them." It goes on to say, "...The average number of spyware components per computer was 93 with one computer having well over a thousand."

What is Spyware?


Butte College (www.bctv.butte.edu/support/spyware.html) offers this definition:

“The term ‘spyware’ is broadly defined as any program that gets into your computer without permission and hides in the background while it makes unwanted changes to your user experience.
Spyware is generally not designed to damage your computer. The damage it does is more a by-product of its main mission, which is to serve you targeted advertisements or make your browser display certain sites or search results.
At present, most spyware targets only the Windows operating system (Internet Explorer).”

To be fair, spyware can be harmless, for example tracking cookies don’t do much. While such things infringe on your privacy, they don't really harm anything. Others, however, are extremely dangerous.

So what do you do about it?

No spyware program seems to do everything, but there are a lot of goods solutions out there that can help. Here is a list of some of the top Spyware tools to look at:

1) Try Ad-Aware 6. 0 Professional from LavaSoft (there is also a free version with less functionality)
2) Spybot Search & Destroy from PepiMK Software
3) Xoftspy form Pareto Logic
5) Spyware Guard from Javacool Software is a free program
4) Pest Patrol (now part of Computer Associates by acquisition)
5) McAfee Anti-Spyware

One thing is for certain: you do need to take spyware seriously. For some reason, too many people out there think anti-virus solutions are the end-all solution. They are not.

And, when all else fails?

Finally, as drastic as it seems, if your computer has been infected with a large number of spyware programs, the only solution you may have is backing up your data, and performing a complete reinstall of the operating system.

Protect your computer system

Today, more people use computers for everything from communication to online banking and investment purchase. As we do these things in a more regular basis, we open ourselves up to potential hackers, attackers and crackers. While some may try to phish your personal information and identity for resale, others simply use the computer as a platform to attack other unknowing targets. Here are some easy and cost effective steps you can take to make your computer more secure.

1. Always make a backup of important data and store it in a safe location away from the team.

2. Update and patch your operating system and Web browser software often. If you have a Windows operating system, first go to www.windowsupdate.microsoft.com and run the Upgrade Wizard. This program will help you find the latest patches for your Windows computer. See also www.officeupdate.microsoft.com to locate available patches for your Office programs.

3. Install a firewall. Without a good firewall, viruses, worms, trojans, malware and adware are all easily accessible on your computer to the Internet. Attention should be paid to the benefits and differences between hardware and software based firewall programs.

4. Check your browser settings and e-mail for optimal security. Why do this? Active-X and JavaScript are often hackers to plant malicious programs on your computer. While cookies are relatively harmless in terms of security issues, they still do not follow the movements of the Internet to build a profile of you. At least set the security settings for "Internet zone" A great and your "Trusted Sites" Low Normal.

5. Install antivirus software and configure Automatic Updates so that you receive the most current versions.

6th Do not open unknown attachments. It is not enough that you can recognize the address where it comes from, because many viruses can spread from a familiar address.

7th Do not run programs of unknown origin. Also, do not send these types of programs to friends and colleagues because they contain funny or amusing stories or jokes. They may contain a Trojan horse waiting to infect a computer.

8th Disable hidden file extensions. By default, the Windows operating system is set to "Hide extensions for known file types". Disable this option so that file types displayed in Windows. Some extensions are, by default, continue to remain hidden, but you are more likely to see the file types that are not unusual.

9. Turn off the computer and disconnect the network when not using the computer. A hacker can not attack your computer when you are disconnected from the network or the computer is off.

10. Consider making a boot disk on a floppy disk in case your computer is damaged or compromised by a malicious program. Obviously, you need to take this step before you experience a hostile violation of your system.
