a-squared Anti-Malware download

v5.1 [Aug 29, 2011]
Since version 5: The new, free configurable file guard compares all files that are downloaded or started with about 4 million patterns of known malicious software.
Unlike conventional protection systems Emsisoft Anti-Malware does not only check files, but it also constantly monitors the behavior of all active programs and raises an alarm as soon as something suspicious happens.
Typical ways of infection are disabled in advance. Websites that try to plant trojans or spyware or that offer deceptive contents are blocked by the surf protection.
Signature updates at least 5 times per day, in combination with the zero-day protection of the behavior analysis this guarantees the best possible protection from new infections.

v3.5 [Mar 8, 2008]
To avoid too many alerts on good programs, version 3.5 introduces the new community based alert reduction feature. Once an alert is triggered, you can see how other users decided about the alerted program. The self protection has been significantly improved. New detection types were added too.
