Backdoor.Win32.IRCBot is a backdoor computer worm that is spread through MSN Messenger and Windows Live Messenger. Once installed on a PC, the worm copies itself into a Windows system folder, creates a new file displayed as "Windows Genuine Advantage Validation Notification" and becomes part of the computer's automatic startup. In addition, it attempts to send itself to all MSN contacts by offering an attachment named 'photos.zip'. Executing this file will install the worm onto the local PC. The Win32.IRCBot worm provides a backdoor server and allows a remote intruder to gain access and control over the computer via an Internet Relay Chat channel. This allows for confidential information to be transmitted to a hacker.
I was also wondering about this, I know QT's frequently throw false positives but this isn't one that I've seen before... anybody?
