None of the Shields Working?

Hi,
I recently booted up my Computer to find that none of avast’s Shields are running. When I try to enable them through Avast it doesn’t work and When I try through the Win7 Action Centre I get a “File System Shield provider not found”.
I’ve restarted twice to no avail. Any Help Would be much Appreciated

Thanks,
Floul1

If the link posted in the previous post did not work, please try the following:

I suggest an uninstall of Avast and CLEAN install to fix your problems.

Please follow these instructions:

  1. Save a copy of newest version of Avast (5.0.545).
  2. Save the http://www.avast.com/uninstall-utility on your hard drive.
  3. Disconnect from the Internet at this time.
  4. Uninstall Avast through “Add/Remove Programs”.
  5. Boot into Safe Mode and run the Avast Uninstall Tool. NOTE: If you also had Avast version 4.0 and 5.0 on your machine, you will need to uninstall BOTH versions this way.
  6. Reboot twice.
  7. Clean your computer up.
  8. Install the newest version of Avast and reboot twice.
  9. Get Internet access and update Avast definitions.
  10. Register your copy or add the license key for Free, Pro or AIS.
  11. Reset your settings, if needed.

Please let us know if you have any further questions or problems after completing the above.
