More Information
W32/Sdbot-NV is an IRC backdoor Trojan and network worm.
W32/Sdbot-NV copies itself to network shares protected by weak passwords.
When first run W32/Sdbot-NV copies itself to the Windows system folder as gfeqzvq.exe and sets the following registry entry to ensure it is run at system
logon:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Mcsoft = gfeqzvq.exe
Each time W32/Sdbot-NV is run it attempts to connect to a remote IRC server
and join a specific channel. The worm then runs in the background allowing a remote intruder to issue commands which control the computer via IRC channels.
