Thank you.

I want to remove AVG product version1.126.2.56387 and AVG PC Tune Up version 16.72.2.55508.
Those are free ones. Now I bought McAfee and first I have to remove AVG before I can set up my purchase. When I try to remove AVG there always seems to be some kind of problem and I can get rid of them. Is there anyone who is clever and would like to help me?
