what is backdoor virus?

The backdoor Trojan is a program that allows hackers access to others' computers. The threat to a user is very great, because the backdoor allows valuable data and passwords to be easily viewed and recorded by the hacker. Because it is subtle and deeply imbedded into the victim's system, the backdoor Trojan is difficult to detect and even more difficult to remove.

One of the most insidious computer viruses today is the backdoor Trojan. The name backdoor Trojan comes from a melding of metaphors. The term Trojan comes from a reference to the legendary Trojan horse that destroyed the city of Troy during a war with Greece. Like the Trojan horse the backdoor Trojan at first looks like a gift, only later does the user find that the enemy was hidden inside.The Trojan horse backdoor virus is comprised of two parts. The first part is the "server". This is the part of the virus that infects the system, and opens the backdoor into the computer. The second part is the "client". The client is the part installed on the intruder's computer that allows the intruder to find and access the server, thereby gaining access to the victim's computer.
