More Information
Troj/Sdbot-HN is a backdoor Trojan which allows a remote intruder to access and control the computer via IRC channels.
When first run the Trojan moves itself to the Windows System folder as svshost.exe and creates the following registry entry, so that svshost.exe is run automatically each time the computer is started:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
svshostdriver= svshost.exe
The Trojan runs continuously in the background and when an internet connection is available, tries to connect to a remote IRC server and join a specific channel. The Trojan then listens on the channel for commands to execute.
