The user should keep in mind that trojans are often disguised as such software.
Therefore Avira AntiVir's AHeAD heuristics may detect such files as well. Please note that cracks or the cracked program files themselves as well as key generators are often modified with similar techniques. Usually such files are protected by encryption mechanisms and are often manipulated afterwards to hide the real functionality. HEUR/Crypted in particular signals files that have a suspicious structure of the program. 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.
To achieve this, Avira performs innovative structural analyzing. Avira AntiVir recognizes unknown malware proactively using its AHeAD technology. HEUR/Crypted is a heuristic detection routine designed to detect common malware characteristics.
