  1. Uninstall Avast by control panel [If you don’t have Avast in control Panel go to #4]
  2. Uninstall in safe mode using Avastclear.
  3. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn’t) - reboot.
    Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle… if so, uninstall it and reboot.
  4. Install the version you downloaded.
  5. Reboot.

The Avast Emergency Updater is causing this problem. Unfortunately, that feature is completely broken in Avast 2014. I am having the same freezing problems. The solution is to turn off avast self-protection module in avast troubleshooting settings, enter task manager, and end the 154235523-5353somemorenumbers.exe process, which is the avast emergency update file as it is digitally signed by Avast. After killing the process, the freezing is gone. Happens several times a week for me, and I never had this problem with previous versions before updating to 2014, which I now realize was a mistake.

Do you have the MSVP host file installed ?

Nope, I have a clean hosts file. Haven’t installed any custom hosts files.
