Do you have a Virus?

Are you infested with pop-up ads, new toolbars in your browser, is your home page changed or are you bombarded with irritating spam? Perhaps your computer is running very slow or worst, you can't get on the internet. If so, your PC is most likely infected with adware, anti adware, spyware, spybot, trojans, viruses or another internet parasite. Viruses won't go away anytime soon! More than 60,000 viruses have been identified, and new viruses are created every day, according to the International Computer Security Association.

What is a Trojan?

A Trojan is malware that performs unexpected or unauthorized, often malicious,
actions. The main difference between a Trojan and a virus is the inability to
replicate. Trojans cause damage, unexpected system behavior, and compromise the security of systems, but do not replicate. If it replicates, then it should be
classified as a virus. A Trojan, coined from Greek mythology's Trojan horse,
typically comes in good packaging but has some hidden malicious intent within its code. When a Trojan is executed users will likely experience unwanted system problems in operation, and sometimes loss of valuable data.
