You can either wait for the next Avast update to see if this fixes your problem, or try an Avast Repair:

  • Go to Control Panel > Add/Remove programs > Avast Antivirus.
  • Scroll down and choose Repair function in the pop-up window.
  • Reboot.

If neither of these fix your problem, then I suggest doing an Avast uninstall, using the new Avast uninstaller tool and a clean install:

  1. Save a copy of Avast 6.0.1000 and save it to your HDD:
    Free: http://files.avast.com/files/avast6f...up_av_free.exe
  2. Download the Avast Uninstall Utility http://files.avast.com/files/eng/aswclear6.exe and save it to your HDD (it has uninstall tools for all Avast versions and products).
  3. Disconnect from the Internet at this time.
  4. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
  5. If Step 4 fails, boot into Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool. Uninstall all previous versions and products you had on your machine at this time.
  6. Reboot.
  7. Install the newest version of Avast and reboot.
  8. Get Internet access and register your copy or add the license key for Free, Pro, or AIS.
