Avast Premium Security is more than just antivirus. It provides complete online protection for all of your computers, phones, and tablets. The software has custom features for PC, Mac, Android, and iPhone/iPad secure your devices where it’s needed most. 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.
The Avast award-winning and certified antivirus engine and shields stop even previously unknown threats – for peace of mind when you chat or spend time on Facebook, Twitter, or other websites.
The silent firewall stops hackers and other unauthorized entry attempts to your PC, to keep your data where it belongs – safe and sound. The antispam feature blocks both spam and sophisticated “phishing” attempts, to keep you from clicking “harmless” links that really can cause damage.
