Are you using both avast! Anti-virus and Norman Security Suite? If so, see the IMPORTANT NOTE about not using more than one anti-virus program in this topic: Choosing an Anti-Virus Program

Try doing a clean install/reinstall of avast as follows:

Download the follwing and save all files to your Desktop.Go to Add/Remove Programs or Programs and Features in Control Panel, select 'avast! Anti-Virus, click the Change/Remove button...when the avast Free Setup GUI opens, click Uninstall. Be sure to reboot when done.

Restart your computer in Safe Mode.
  • Double-click on avastclear.exe to run the utility.
  • If you installed avast! in a different folder than the default, browse for it. (Note: Be careful! The content of any folder you choose will be deleted!)
  • Click REMOVE.
  • Restart your computer.
Run RejZor's avast Uninstall tool (avast-cleanup-tool) in Normal Mode.

Once uninstalled, open Device Manager > View > Show Hidden devices and check for anything related to avast with a yellow triangle. If found, remove it and reboot the computer.

Install the avast! setup version you downloaded to your Desktop and restart your computer when finished.
