Avast Pro Antivirus is for people and companies that want a customized computer security package. Antivirus and internet protection components in Avast Pro Antivirus are built for easy integration with existing firewalls in users' home or work computers. Pro Antivirus has two major additions to the core protection elements in Avast Free Antivirus: the Script Engine and the Sandbox. The Script Shield and its script detection engine stop malware at the point of entry- web browsing activities. The Script Shield watches scripts executed in the operating system and scans scripts (both remote and local) run as a part of a Web page.

Support Windows 2000/XP/Vista/7
