Dear Community
I am unable to uninstall my Free AVG which blocks at 2% and has also blocked my administrator access.

I keep being asked to install AVG PC TuneUp and have accidentally allowed it to go through its process even though it messed up my computer a few years ago and I kept ignoring it.

This may be why the AVG is not moving past 2%
Please help
