I installed the AVG AntiVirus and as soon as it gets to 99% complete, it shuts down and restarts.
This wouldn't be an issue, but it states I have 32 possible threats.
Hello Tammy,
I'm sorry to hear about this. I request you to check if you have already installed any other AVG program on your mac computer. If no, then please share a screenshot (https://support.apple.com/en-us/HT201361) of the 32 possible threat to assist you further, and also let us know the OS version by following this article: https://support.apple.com/en-us/HT201260.
Best regards,
Alok.
