W32/Sdbot-WS is a member of the W32/Sdbot family of network worms. The worm can spread to weakly protected network shares, and to computers already infected with W32/MyDoom.
In order to run automatically when Windows starts up the worm copies itself to the folder as winupdate.exe and creates the following registry entries:
HKLM\\Software\\Microsoft\\Windows\\CurrentVersion\\Run\\
Windows Update
winupdate.exe
HKLM\\Software\\Microsoft\\Windows\\CurrentVersion\\RunServices
Windows Update
winupdate.exe
HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Run\\

Once installed, W32/Sdbot-WS connects to a preconfigured IRC server and joins a channel from which an attacker can issue further commands. These commands can cause the infected computer to perform any of the following actions:
Scan for remote computers to infect
Steal product keys
Upload, download and execute files
Retrieve information about an infected system
The worm can be instructed to secure an infected computer, and does this by attempting to delete the C$, D$, IPC$ and ADMIN$ network shares, and disable DCOM by setting the following registry entry:
HKLM\\Software\\Microsoft\\OLE
EnableDCOM
N
