W32/Agobot-CS is an IRC backdoor Trojan and network worm that copies itself to network shares with weak passwords.

When first run, W32/Agobot-CS copies itself to the Windows system folder as spolsv.exe and creates the following registry entries to ensure it is run at system logon:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
SpoolService= spolsv.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
SpoolService= spolsv.exe

Each time W32/Agobot-CS is run it attempts to connect to a remote IRC server and join a specific channel.

W32/Agobot-CS then runs continuously in the background, allowing a remote intruder to access and control the computer via IRC channels.

W32/Agobot-CS collects system information and registration keys of popular games that are installed on the computer.

The worm also attempts to terminate and disable various security-related programs.
