The following patches for the operating system vulnerabilities exploited by W32/Rbot-AJT can be obtained from the Microsoft website:
W32/Rbot-AJT 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.

The following registry entries are created to run steam.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
