I used to recommend AVG, but now I don't. I prefer Malwarebytes and Kaspersky for cleaning up systems of infections. When I first started using AVG, it was good, but the last time I used it (and I'm talking the free version), it was crap. I even recommended it to someone that had a virus problem and it worked great for them! And a few years later, they asked the same question again and said they were still using AVG. I felt kind of bad cause I had to tell them to get a different antivirus program!
Glad you were able to figure out what your issue was though and that it was such a simple fix!
