W32/Sdbot-RG is a member of the W32/Sdbot family of worms. It is a network worm and IRC backdoor Trojan for the Windows platform.
When first run W32/Sdbot-RG copies itself to the Windows system folder with the name et3rd.exe. In order to run on system start the worm creates the following registry entries:

W32/SdBot-RG connects to an IRC server and joins a particular channel, providing unauthorised access and control of the computer from an IRC channel.
