|The main reason folk get into a big tiz uninstalling AV's is that they do not stop them functioning before they try. A running AV will rightly protect itself from being impaired because that is what many viruses try to do. There is always a way the user can stop AV's from running - just a matter of clicking around their control panels. |
The same thing applies with third party firewalls - they should also be stopped before attempting an uninstall.
Sure, use an official uninstaller, but another time it is best to give the normal uninstall a fighting chance.
Running two AV's is crazy - they will fight each other like cats and dogs. I have no issue with either of the AV's mentioned in terms of function but would go for Avast because it is lighter on resources and does not intrude unnecessarily.
Always pop back and let us know the outcome - thanks
