Special detection Description:
HEUR/Crypted
HEUR/Crypted is a heuristic detection routine designed to detect common malware characteristics. Avira AntiVir recognizes unknown malware proactively using its AHeAD technology. To achieve this, Avira performs innovative structural analyzing.
On the basis of the composition of a file, the sequence of significant code sequences or based on particular behavior patterns, the heuristics can determine with a high probability whether it is dealing with a harmful or virulent file.
HEUR/Crypted in particular signals files that have a suspicious structure of the program. Usually such files are protected by encryption mechanisms and are often manipulated afterwards to hide the real functionality.
Please note that cracks or the cracked program files themselves as well as key generators are often modified with similar techniques. Therefore Avira AntiVir's AHeAD heuristics may detect such files as well. The user should keep in mind that trojans are often disguised as such software.
In the unlikely occurrence of a false positive we would kindly ask for your help, by sending the file to our virus lab.
A heuristic detection might be a false identification if one or more of the following are true:
- The program is in use for a very long time and is known to the user
- The program was installed by the user himself
- The program is from a trustworthy source
Please note that even old programs can get infected or replaced by malware without your knowledge. Besides that trustworthy sources might have become compromised themselves.
In order to enhance detection and reduce the rate of false positives we recommend that you send the file to our virus lab for further analysis.
