File system shield provider not found

Hi everyone
After cleaning my computer, Avast fails to start, and gives me the message “File system shield provider not found”. Anyone knows what I have to do?

Try avast repair and reboot

Windows, Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button from the pop-up window, scroll down to Repair, click next and follow.

Thanks for the quick respons.
When doing that, i get this message “Error processing packages. Please use full update”

you say cleaning your computer…what type of cleaning was that ?

you may try a complete new install…

remove with this, reboot and install again

Hmmm… I suggest an installation from scratch:

  1. Download the latest version of avast! Uninstall Utility and save it.
  2. Download the latest avast! version and save it.
  3. Uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
  4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after you’ve run it.
  5. Install avast! using the setup saved on 2. Boot.
  6. Register your free copy or add the license key for Pro. Or even upgrade your key from old versions.
  7. Check and post the results. If, for any reason, you did not solve, try doing the step 3 in Safe Mode anyway.

I have reinstalled avast succesfully :wink:

I’m SO glad the problem is solved.
Happy new years :smiley:
