Installing AVG AntiVirus Free version

Since I bought AVG PC Tune Up, AVG Protection does not function. I't's not possible to remove or re-install. What is the best way to resolve this problem ? Ben Helmink

Hello Ben,
We apologize for the inconvenience caused.
As we understand you are experiencing issue with AVG Antivirus free edition, is that right?
May I know the exact error message you have received while you try to reinstall?
Have you tried "AVG remover tool" to uninstall and reinstall?
Thank you.
