  2. Dowload the avast uninstall utility (but don’t run the file yet)
  3. Go to add/remove and uninstall avast and follow the instructions.
  4. Run the tool in step 2 in normal mode and follow the instructions. Let the tool automatically run your windows in safe mode and follow the instructions.
  5. Download your previous antiviru’s removal tool e.g. mcafee, norton, and etc and run it in safe mode.
  6. Install the download file in step 1 and follow the instructions. After successful installation, restart your computer manually and register your copy of avast.

So, you messed around with your system without knowing what you are doing. Since avast has problems after you made the change, the solution seem to be simple. - Undo the change - Follow the instructions to cleanly install avast.

the defualt option is Optin i undo it before you say it
then he is cannot update the program or virus engine
