Emily, AVG AntiVirus isn't compatible with iOS. Currently the only prog associated with AVG that's compatible with iOS is HMA! Pro VPN (http://www.avg.com/ww-en/hma-pro-vpn).

I may have received a virus threat on my iPhone 6S Plus via a political email that I received in November. I am unable to place the email message into my trash for the email account that received the message … no matter how and as many attempts I have made! Is it possible to have AVG for my iPhone to scan for this potential virus? I do have AVG for my home iMac desktop and my MacBook Air laptop. Any suggestions would be deeply appreciated. Thank you very much for your help!! Emily Gray
