W32/Rbot-CJ is a worm which attempts to spread to remote network shares. It
also contains backdoor Trojan functionality, allowing unauthorised remote
access to the infected computer via IRC channels while running in the
background as a service process.

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

W32/Rbot-CJ moves itself to the Windows system folder as WUAGTRD.EXE
and creates entries called MICROSOFT UPDATE at the following locations in
the registry so as to run itself on system startup:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
