12.1.1.4. Heuristics 

This configuration section contains the settings for the heuristic of the scan engine. 
AntiVir products contain 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. 

Macrovirus heuristics 

Macrovirus heuristics 

Your AntiVir product contains a highly powerful macrovirus 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) 

enable AHeAD 

Your AntiVir program contains a very powerful heuristic in the form of AntiVir AHeAD 

technology, which can also detect unknown (new) malware. If this option is enabled, 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, slightly less unknown malware is detected, 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 the use of this heuristic. 

High detection level 

If this option is enabled, significantly more unknown malware is detected, but there are 

also likely to be false positives. 
 

12.1.2 Report 

The Scanner has a comprehensive reporting function. You thus obtain precise 

information on the results of an on-demand scan. The report file contains all entries of 

the system as well as alerts and messages of the on-demand scan. 
Note 

To enable you to establish what actions the Scanner has performed when viruses or 
unwanted programs have been detected, a report file should always be created.
