  The Difference Between a Virus, Worm and Trojan Horse?
The most common blunder people make when the topic of a computer virus arises is to refer to a worm or Trojan horse as a virus.
Viruses, worms and Trojan Horses are all malicious programs that can cause damage to your computer, but there are differences among the three, and knowing those differences can help you to better protect your computer from their often damaging effects.
Trojans are also known to create a backdoor on your computer that gives malicious users access to your system, possibly allowing confidential or personal information to be compromised.
