More Information

W32/Rbot-DDH is a worm and IRC backdoor Trojan for the Windows platform.

W32/Rbot-DDH 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/Rbot-DDH copies itself to <System>\adkillers.exe and creates the file \%CurrentFolder%\aspr_keys.ini.
