Avast antivirus software is better than AVG

AVG has been busy sending me popups asking me to buy their product, meanwhile AOL said my email had suspicious activity going on. I used the I forgot my password on the AOL signin and changed it to get past the call 1 855 678 5082 message and I also added Mozilla to that email account. I downloaded and ran Malwarebytes which found 73 suspicious files. Then I went back to Windows 10 insider because one of the sites telling me how to fix the AOL problem (call 1 855 678 5082 message) was unsafe according to Avast but not AVG. I already suspected something because the registry files they were telling me to delete did not exist.
