“Avast Antivirus is for individuals or companies that want customizable computer security that will integrate easily with an existing firewall. It has all the features of Avast Free Antivirus, plus a command-line scanner, full-scale virtualization, and the new Avast SafeZone (a clean, isolated desktop, so that other applications--even keyloggers--cannot see what's happening), designed specifically for secure online shopping or banking. Provides even faster protection than its predecessor and offers a web-reputation browser extension as well, all combining for real-time security against known and unknown forms of malware. Accurate threat updates via Avast CommunityIQ technology ensure worry-free downloading, surfing, social networking, and gaming.”
