I left “Avast Antivirus” service running, and just stopped “Avast! iAVS4 Control” Service. Thats when I get my normal fast shut down. (around 5 secs.)

Stopping the “Avast Antivirus” service, and leaving “Avast! iAVS4 Control” Service running, does nothing. I still get a long(20 seconds) shutdown.

If you want my PC configuration, both hardware and software, let me know.

Hope that helps!
