Hm…maybe a clean install will do!

  1. Download the avast uninstall utility here:
    http://www.avast.com/uninstall-utility

  2. Download the avast internet security here:
    http://www.avast.com/download-thank-you.php?product=ISE&locale=en-ww

  3. Uninstall the avast present in your system using the ‘avast uninstall utility’ (The one in step 2) via Safe Mode

  4. Reboot your computer

  5. Finally run the avast Internet Security installer ;D

I hope it works :slight_smile:
