Having to protect your computer from outside threats is something which is a constant battle for most computer users, especially those of us who use the net on a daily basis.
Malicious software (or malware) is software which can appear legitimate, but will include hidden Trojans such as Blaster, Sasser and Mydoom. Trojan deve lopers are becoming more ingenious in the way they target Internet users, and the software is often undetected by standard virus detection software.
