Hi friends This post is like a small introduction of Trojan..
Remember the Trojan Horse? Bad guys hid inside it until they could get into the city to do their evil deed.
A trojan computer program is similar.
It is a program which does an unauthorized function, hidden inside an authorized program.
It does something other than what it claims to do, usually something malicious (although not necessarily!), and it is intended by the author to do whatever it does.
If it's not intentional, its called a 'bug' or, in some cases, a feature.
Some virus scanning programs detect some trojans. Some virus scanning programs don't detect any trojans. No virus scanners detect all trojans.
