More Information

W32/Agobot-IS is an IRC backdoor Trojan and network worm.

W32/Agobot-IS is capable of spreading to computers on the local network
protected by weak passwords.

When first run W32/Agobot-IS copies itself to the Windows system folder as
winasp.exe and creates the following registry entries to run itself on
startup:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Video Process

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Video Process

W32/Agobot-IS also registers itself as a service which will be activated when
Windows starts up. The name of the service is Video Process.

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

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

W32/Agobot-IS attempts to terminate and disable various anti-virus and
security-related programs.
