Following an auto update, Avast did a full scan on Win 7 PC reboot. Now Avast Pro crashes every time I try to start it. Have tried Repair and reinstall but it always crashes with this detail:

When you re-installed did you run the Avastclear programme ? 

Download Uninstall Utility to your Desktop.
Download the correct version of Avast 
Avast Free
Avast Pro
Avast Internet Security
Avast Premier
Disconnect from the net
Uninstall Avast via control panel

  • Run aswClear
  • It will offer to reboot to safe mode

  • In the Select Product to Uninstall dropdown choose the version of Avast that is on your system.
  • Press Uninstall
  • Once complete reboot your system to Normal Mode
  • Reinstall Avast
