Fire Wall won't start after updating Windows 10

[REDACTED]

Greetings,

Any ideas as to why I can't start my fire wall after updating my window 8.1 to 10? I have updated my Avast software to the current config, but still nadda. Not sure if I need to do a full uninstall of Avast and reinstall. Any suggestions are greatly appreciated!!

Thanks

Indeed, I suggest an installation from scratch.
It was the easy way for me to upgrade to Windows 10.

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...

Hi All,

I ran into same issue of Firewall not being able to start after upgrading to Windows 10 today but found a quick fix. Simply go to 'uninstall applications' in Control Panel, Select AVAST and click 'CHANGE' then 'REPAIR'. Once finished, reboot and Firewall will work will no issue.

Hope this helps!
