Avast Causing Windows 7 to hang at start up

Avast Free Antivirus / Premium Security
1

Hi all
This morning when i turned my computer on it hung on the “windows loading” screen. I managed to boot up in safe mode and perform a virus scan with avast and malewarebytes. They each returned a couple of infection which I removed, but it made no difference.

Following this I performed a clean boot using msconfig to boot with just windows startup files and services. After a few reboots editing the startup options each time I discovered that avast was the problem, and that when I stopped it from starting at boot up my system runs fine.

When I open avast up after booting the summary page says “UNSECURED” …the fix button does nothing at all.

Thanks for any help
Al

I had a similar problem this morning on my Win 7 Premium x64 box.

Computer wouldn’t boot properly… and was different symptoms. Either would hang on Welcome screen, or get to desktop but not put up icons/taskbar, or it would show icons/taskbar but not respond. Safe-mode boots with/without network always worked OK.

Had to use System Restore and go back about 6 days… going back to 5-8 didn’t work. Went back to 5-4 and it seemed OK. Windows Update re-applied about 18 updates, and then seemed to boot OK, except Avast was in that “Unsecured” state and the fix/start service buttons did nothing.

I ended up uninstalling Avast, rebooting, reinstalling, reboot and now it seems OK.
