A Worm is a virus-like software application which spreads itself to other computers. Worms send themselves out to email addresses collected from the infected PC. Worms are known to mutate and they usually carry a destructive payload.
This malicious program uses its specific algorithms for harming the infected system in various ways. Firstly, it changes several Internet settings; this makes it impossible for the user to connect to antiviral servers for getting updates for his or her security system. After that, Agobot.Trojan searches for IRC (Internet Relay Chat) client and infects it. As a result of this, the hacker is able to connect to the infected machine via IRC and perform dangerous activities, such as stealing various confidential pieces of data.
