Single- and Multi-Device options let you choose the protection that works best for you. “Up to 10 devices” means you can share your security with every one of your devices or everyone closest to you.
Avast Premium Security protects against all online threats, including spoofed websites and ransomware. Complemented by SafeZone technology, it creates an isolated virtual desktop, invisible to any possible attacker, where you can do your online shopping and banking securely.
