When using avg tuneup, it no longer cleans out the browser history

Hello Patty,

We'll certainly look into this and help you.
Initially, please check & mention program version of AVG TuneUp installed on your computer.
If it's the latest version (20.1), kindly follow the below instructions to repair your AVG TuneUp program:
Open Control Panel > Programs and Features > Program List > Find AVG TuneUp in that list > click on "Uninstall" > A window will pop-up prompting Uninstall/Repair > Proceed with Repair.
After repairing your AVG TuneUp program, kindly check if the issue persists.
Thanks in advance.

I put a check mark in the box to clean this but the check mark quickly goes away.  This has been happening for about two days. Can someone help me? Thank you.  This is the first time I've had a problem with the tune up.
