Something like that happened to me months ago only it was the opposite.
AVG messed up and after removing every last bit of it and installing Avast, several problems were found.
Apparently no security software is perfect.
Hi LJ, Lol I had to search back for your comment as I got behind.
I’ve gone back and forth on antivirus programs and have had both mess up over the years. But - I probably do more downloading of graphics and music than most people and sometimes pick up things.
Right now AVG is working fine and I just knocked on wood, lol.
