Antivirus programs are so stupid, so they discover "virus" in helloworlds. Perhaps some idiots write malware in Pelles C, and “wise” AV add a sign to the detection of viruses.
This problem is already 15 years old, stubs of assemblers, visual studio 6, UPX and so on are also detected. Heuristic analysis should be thrown in the trash for a long time, (both with all antiviruses).
