A Trojan is not necessarily a denial of service attack. They are usually a
program that a user is tricked into installing willingly onto their
computer. The Trojan may be a backdoor to your computer/network, it may
capture keystrokes, steal data, or have other purposes and may want to stay
stealthy. Worms are very destructive in that they propagate through network
connections and try to infect as many computers as possible and there
presence usually becomes painfully obvious, such as blaster causing
computers to constantly reboot. I will never forget when I got nimda on my
home network. The link below is to the Microsoft Antivirus in Depth Guide
that you may find useful. --- Steve
