Warning
Enter the URLs you want to exclude from the Web Protection scan as precisely
as possible. Avoid specifying an entire top-level domain or parts of a second-
level domain because there is a risk that Internet pages that distribute malware
and undesirable programs will be excluded from the Web Protection scan
through global specifications under exclusions. You are recommended to
specify at least the complete second-level domain and the top-level domain:
domainname.com
Heuristic
This configuration section contains the settings for the heuristic of the scan
engine. (Options available in expert mode only.)
Avira 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 heuristic
Your Avira 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 Avira program contains a very powerful heuristic in the form of Avira 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.
