Ok I am back home, and had some time to test some things for you guys. First let me say that I am in no way trying to put Avast AV down. I am just making some observations, and trying to help with the solution.

Ok I went into services and saw two items listed for Avast.

  • Avast Antivirus

  • Avast! iAVS4 Control Service

Ok, if I stop just the “Avast Antivirus” service, the slow shutdown continues. However, if I stop the “Avast! iAVS4 Control Service”, I have a very speedy shutdown (under 5 seconds after the “windows is shutting down” text appears.

I hope this helps!
