Beneath its deceptively simple design lies a powerful security engine that works in real time to detect and remove not only Mac-specific viruses and spyware, but PC and mobile threats, too. So AVG AntiVirus not only helps protect all that's important on your Mac, it also prevents you from infecting friends on other devices. Our award-winning detection technology scans for Mac, PC, and Android-based viruses and spyware. So you can feel better
knowing your beloved Mac is protected -- and that you're not sharing viruses with any of your other devices or with your PC and Android friends.
