W32/Rbot-AGL

Please follow the instructions for removing worms.

W32/Rbot-AGL is a worm which attempts to spread to remote network shares. It also contains backdoor Trojan functionality, allowing a remote intruder access to the infected computer via IRC channels.

W32/Rbot-AGL spreads to network shares with weak passwords and via network security exploits as a result of the backdoor Trojan element receiving the appropriate command from a remote user.

W32/Rbot-AGL copies itself to the Windows system folder with the filename Autopdate.exe and creates entries at the following locations in the registry with the value "Autopdate" so as to run itself on system startup, resetting these values every minute:

HKCU\SYSTEM\CurrentControlSet\Control\Lsa

HKLM\SOFTWARE\Microsoft\Ole\EnableDCOM = "N"
HKLM\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous = "1"

W32/Rbot-AGL attempts to delete network shares on the host computer every 2 minutes.
