Avast Internet Security 2017 – provides complete antivirus, anti-spyware, antispam, and firewall protection, complemented now by new avast! SafeZone technology. It creates an isolated virtual desktop, invisible to any possible attacker, where you can do your online shopping and banking securely. avast! SafeZone opens a new (clean) desktop so that other programs don’t see what’s happening – and it leaves no history once it’s closed.
