I have been using Avast Free for several years now without problem, until very recently.
I decided to pay and upgrade to the Pro version 2015
Whenever I start my laptop none of the shields nor the Avast Background Service start automatically. The rest of Avast starts and seems to function fine, but these specific components do not. Now every time I start up my laptop I need manually start the Shields and background service.
After looking through some older threads I have tried using the "repair" option in the Avast uninstaller to no effect (including reboot). I have also tried completely uninstalling (including reboot) and then subsequently reinstalling Avast, also to no effect.
After a quick search I've found the relevant uninstall tool (
https://www.avast.com/en-us/uninstall-utility) and will try using it to remove avast. I completed this in safe mode. restarted, restarted again, installed and I have the same issue.
So Basically I'm back where I started. The uninstaller did not appear to have any discernible effect on the behavior of Avast.
Also, no definition or software updates work properly.
I am running Windows 8.1 64 bit.
