My Avast Pro wont start up, won't turn on, even after repair and reinstall it has switched off and won't turn on and won't update. I have tried everything I can think of and this is an issue that seems to have no permanent fix. I am wasting huge amounts of my time trying to resolve it when this should never be of concern. I payed for something I can't get.
Do you have any other security app running alongside with Avast? (firewall, another antimalware...?).
Is your computer virus free?
Anyway, 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. (Optional) If you want, save your Avast settings for later restoration (Settings > Maintenance > Back up).
4. Uninstall Avast from Control Panel (if possible) and reboot.
5. Run the Avast Uninstall Utility saved on 1 in and
follow the instructions. Reboot Windows in Safe Mode, uninstall Avast and then reboot in Normal Mode again.
6. Install Avast using the setup saved on 2. Register your free copy or add the license key for the paid versions. Boot.
7. Check and post the results.
Please, be patient, boot when it's said to boot...
