More Information
W32/Rbot-GOU is a worm for the Windows platform.
W32/Rbot-GOU runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
When first run W32/Rbot-GOU copies itself to <System>\tskmngr.exe.
The following registry entries are created to run tskmngr.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Task Manager
tskmngr.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Task Manager
tskmngr.exe
The following registry entry is set, affecting internet security:
HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy
\StandardProfile\AuthorizedApplications\List

Note: disabling autostart for the SharedAccess service deactivates the Microsoft Internet Connection Firewall (ICF).
