More Information

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

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

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

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
System Updater Service = wmiprvsw.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
System Updater Service = wmiprvsw.exe

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

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

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

W32/Agobot-HD includes a stealthing component which attempts to hide the worm.
