I read an article on softwarecrew.com (http://www.softwarecrew.com/2011/01/avast-updates-its-free-and-paid-anti-virus-suites-to-5-1/)about a heuristics engine that Avast introduced with 5.1 release. Just wondering what it is and the benefit? Thanks.
Heuristics are designed to detect previously unknown viruses before they can cause any harm. For more info see
