Free trojan horses virus software for windows

In Greek mythology, the Trojan horse was a giant wooden horse on a wheeled platform that appeared to be a gift left by an attacking army who apparently had finally given up on the siege and gone home. The defending city, overcome by a sense of pride and celebration, happily wheeled the structure inside the city walls.
That proved to be a fatal mistake. The huge, heavy structure was actually hollow and was full of the best-trained enemy soldiers. Late at night they quietly exited the horse and laid waste to the city, a task made easier by the defending soldiers being passed out from the drinking and partying earlier in the evening.
In modern times, a Trojan horse is a computer virus classified under the spyware category. It is the most dangerous type of spyware to have on your machine, and should not be taken lightly. Typically they are a keyboard-logger program. Meaning that they record your keystrokes and send them back to the criminal who snuck the program on to your machine, often enabling him to steal the passwords to your financial accounts.
This type of virus gets it's name from the fact that it is known for getting on your computer by being "disguised" in something much more innocent - such as downloading graphics, music files, or what you thought was another free program entirely. However, that is not the only way to get them!
These viruses are, unfortunately, relatively simple pieces of code. They can be embedded in html email, meaning that if you enable images and links in emails from strangers you could be susceptible to acquiring one. They can be set to load onto your computer simply by clicking on the wrong web page link.
The only defense is to have both anti-virus and anti-spyware software running on your machine, full-time. Even though the coding for this type of spyware is simple, trojans are often missed by the bigger anti-virus programs (maybe even because they are such simple codes). If you do any amount of web-browsing it is only a matter of time before you get one of these things.
The best-selling anti-spyware program in the 21st century so far is No Adware. While free anti-spyware programs are available, a prudent web surfer will protect themselves with the higher quality product - as it's just not worth risking the modern nightmare that identity theft has become. No Adware will safely remove any Trojans that are already on your computer, and protect you from being victimized by any that you run into in the future. We highly recommend it.
