More Information

W32/Sdbot-ACD is a worm and IRC backdoor Trojan for the Windows platform.

W32/Sdbot-ACD runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.

When first run W32/Sdbot-ACD copies itself to <System>\windir32.exe.
