I installed the AVG Antivirus Free and somehow ended up with the trial version of the paid version. When the trial period ended several weeks ago I started getting daily popups stating that my trial had ended and giving me no options except a "Remind me Later" and a "Buy Now" button. I went to AVG support and followed their so-called instructions for getting rid of the popups. Still getting it every single day. How can I finally and completely get rid of this annoying popup?
