More Information
W32/Rbot-BBI is a worm with backdoor functionality for the Windows platform.
W32/Rbot-BBI can spread via the following common buffer overflow exploits:
LSASS (MS04-011)
RPC-DCOM (MS04-012)
WebDav (MS03-007)
UPNP (MS01-059)
as well as to computers infected with the following worms:
W32/MyDoom

as well as to weakly protected network shares.
W32/Rbot-BBI 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.

diskmon32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
