Avira AntiVir Premium Help
Configuration :: MailGuard :: Scan
This configuration section contains the settings for the heuristic of the Avira AntiVir Premium search engine.
Avira AntiVir Premium contains very powerful heuristics that can proactively uncover unknown malware, i.e. before a special virus signature to combat the damaging element has been created and before a virus guard update has been sent. Virus detection involves an extensive analysis and investigation of the affected codes for functions typical of malware. If the code being scanned exhibits these characteristic features, it is reported as being suspicious. This does not necessarily mean that the code is in fact malware. False positives do sometimes occur. The decision on how to handle affected code is to be made by the user, e.g. based on his or her knowledge of whether the source of the code is trustworthy or not.
Avira AntiVir Premium contains a highly powerful macro virus heuristic. If this option is enabled, all macros in the relevant document are deleted in the event of a repair, alternatively suspect documents are only reported, i.e. you receive an alert. This option is enabled as the default setting and is recommended.
Advanced Heuristic Analysis and Detection (AHeAD)
Avira AntiVir Premium contains a very powerful heuristic in the form of AntiVir AheAD technology, which can also detect unknown (new) malware. If this option is activated, you can define how "aggressive" this heuristic should be. This option is enabled as the default setting.
Low detection level
If this option is enabled, Avira AntiVir Premium detects slightly less unknown malware, the risk of false alerts is low in this case.
Medium detection level
This option is enabled as the default setting if you have selected application of this heuristic. This option is enabled as the default setting and is recommended.
High detection level
If this option is enabled, Avira AntiVir Premium identifies far more unknown malware, but you must also accept that there are likely to be false positives.
