Hello Robert,
I understand your concern. To best assist you with this, I suggest you to get connected to our AVG remote support. They will help you in removing the old AVG files from your computer. I have emailed you the link to get connected to AVG remote team.
And where can we find "AVG Clear" and "AVG Remove"? NO link provided. De-install program AVG is a Windows function!
Robert, They are both situated within the link (https://support.avg.com/SupportArticleView?l=en&urlName=How-to-troubleshoot-issues-after-upgrade-to-the-latest-AVG-antivirus-product)!!!
