Trojan - A trojan is a program that does something undocumented that the programmer intended, but that some users would not approve of if they knew about it. According to some people, a virus is a particular case of a Trojan, namely one which is able to spread to other programs. According to others, a virus that does not do any deliberate damage is not a Trojan. Finally, despite the definitions, many people use the term "Trojan" to refer only to *non-replicating* malware, so that the set of Trojans and the set of viruses are disjoint.
OR, you could just say the truth:
A Trojan Horse (trojan for short) is a program designed specifically to open backdoors to your computer. A trojan often comes bundled with regular programs, to appear safe to the average computer user. Once the bundled software is executed, the trojan either loads itself into the memory, or drops other .exe files with seemingly legitimate "Windows-ish" names into system folders. These exe files will then re-open the backdoor every time the computer is connected to the net.
Trojans are mostly used by the novice to intermediate hacker, as a way of gaining access to computer systems not belonging to them.
Trojans do not inprint their code into other programs, but as mentions before often drops other .exe files.
What makes a good trojan such a threat is the fact that newer trojans have the ability to unload any virus protection you may have, and often completely bypass any software and/or hardware firewall. The recommended solution to those problems would be having an antivirus software capable of determining and containing a trojan before you have a chance to run it. My personal favourite is Symantec AntiVirus Corp 9. It is made by the same people who creates Norton AntiVirus (which is highly NOT recommended as an antivirus). What SAV lacks in fancy looks, it makes up for in speed and reliability.

As a personal note, I have never had a single virus/trojan on my computer since I started using the above program.
And as for what I know about trojans, well I used to play around with them, so believe me I know how at least SOME of them work.

I decided I had to correct the quoted text, because it is basically a whole paragraph with beating around the bush about whether or not to define a trojan as a virus or not, instead of focusing on what it actually IS and what it DOES.

I have never had a trojan or virus since I started using common sense while browsing and downloading stuff.

Don't use a virus scanner and I just use windows sp2 firewall.

Scan with pandas online scanner every now and then but it never finds anything

Another good new program for security being recommended by Alliance of Security Analysis Professionals members is Ewido Security Suite 3.5

Ewido Security Suite is a supplement to your current Anti-Virus Program.
NOTE: It will only work on Win2K and XP systems.

Please follow the instructions provided, you may want to print out these instructions and use them as a reference.

Please download ewido security suite it is a free version of the program.
  1. Install ewido security suite
  2. When installing, under "Additional Options" uncheck..
    • Install background guard
    • Install scan via context menu
  3. Launch ewido, there should be an icon on your desktop, double-click it.
  4. The program will now open to the main screen.
  5. When you run ewido for the first time, you will get a warning "Database could not be found!". Click OK. We will fix this in a moment.
  6. You will need to update ewido to the latest definition files.
    • On the left hand side of the main screen click update.
    • Then click on Start Update.
  7. The update will start and a progress bar will show the updates being installed.
    (the status bar at the bottom will display "Update successful")
If you are having problems with the updater, you can use this link to manually update ewido.
ewido manual updates

Once the updates are installed do the following:
  • Click on scanner
  • Click on Complete System Scan and the scan will begin.
  • While the scan is in progress you will be prompted to clean files, click OK
  • When it asks if you want to clean the first file, put a check in the lower left corner of the box that says "Perform action on all infections" then choose clean and click OK.
  • Once the scan has completed, there will be a button located on the bottom of the screen named Save report
  • Click Save report.
  • Save the report .txt file to your desktop.
Now close ewido security suite.


Now what I do reccomend you do is just generate your log file and pop on over to ComputerCops and they have a dedicated forum where users can post their HijackThis logs and have an expert analyse it and tell you what to edit/delete.
ANY of these sites can help:
5 Star Support

Common Sense Security
Geeks to Go
Gladiator Security
JSKYs XP Support
Linha Defensiva

Along with a variety of scan options, AntiSpyware includes a scheduler, active protection, and a useful set of advanced features. Spyware scan times are reasonably fast and seem thorough. After installation, a configuration wizard greets users, taking them step-by-step through running a scan and setting up a schedule. Novices may get a bit lost in the interface--it includes three large buttons for navigation but could use a home button to take users back to the Summary screen. Controls in the interface, such as menus and scroll bars, don't behave as well as controls in other Microsoft applications. Advanced tools include a privacy eraser, a file analyzer, and a system explorer, which lets you look at and install browser toolbars, among other things. The scheduler is particularly nice, letting you, for example, set a deep scan to run every night. Besides a few interface issues, Microsoft Windows AntiSpyware is an exceptional spyware remover.

Of course, the best solution is to just stop using Windows.
