Avast Internet Security

Avast Internet Security has all the features of Avast Free Antivirus, plus a Silent Firewall, an antispam filter, a command-line scanner, 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. Leaner and meaner version 6.0 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. Avast Internet Security provides maximum protection, designed for those who shop and bank online or store sensitive data on their computers. Accurate threat updates via Avast CommunityIQ technology ensure worry-free downloading, surfing, social networking, and gaming.
