7.4 Heuristic Detection<br />

<strong>Avira</strong> Mac Security contains a highly powerful heuristic and macro virus heuristic that can<br />

proactively detect unknown malware and new viruses. It enhances the so called signature<br />

based detection which looks for known viruses. Macro viruses are small programs that are<br />

written in the macro language of an application (for example WordBasic under WinWord<br />

6.0) and that can normally spread within documents of this application. For this reason,<br />

they are also called document viruses, you may receive per email. In order to be active,<br />

they need that the corresponding applications are activated and that one of the infected<br />

macros has been executed.<br />

Scan for macro viruses<br />

You may turn off the scan for macro viruses.<br />

Use heuristic detection to find new viruses<br />

You may turn off the heuristic detection to find new viruses.<br />

Heuristic Detection Level<br />

By default, the search with heuristic technique is turned on and the detection level is<br />

set to Medium.<br />

You may change the detection level by moving the slider control.<br />

� Low: Weakest detection level with a low risk that clean files will be detected as<br />

infected.<br />

� Medium: Strong detection level with a low risk that clean files will be detected as<br />

infected.<br />

� High: Strongest detection level with a higher risk that clean files will be detected as<br />

infected.<br />
