This is a heuristics detection
of possible new variants of malware
before the vendor can get samples and update the program's definitions for detection. Heuristics uses non-specific detection methods to find new or unknown malware which allows the anti-virus to detect and stop if before doing any harm to your system. The techniques involves inspecting the code in a file to see if it contains virus-like characteristics. If the number of these characteristics/instructions exceeds a pre-defined threshold, the file is flagged as a possible virus
to using heuristics is that it is not as reliable as signature-based detection (blacklisting) and can potentially increase the chances that a non-malicious program is flagged as malicious. With heuristics, there is always a potential risk
for a "False Positive
" when the heuristic analysis flags a file as suspicious
that contains no malware. Reducing the detection sensitivity will minimize the risk but then that increases the possibility for new malware to infect your system.PAK_GENERIC.001
This is Trend Micro's proactive detection for suspicious -- and possibly malicious -- executable files that are compressed using Win32 compression tools. This detection also encompasses many appending viruses found in the wild...Send files detected as PAK_GENERIC.001 to the email address email@example.com so that appropriate analysis can be done on the sample...
