I cannot use this program because I always get this virus alert and project build end in complete failure
What virus scanner this time?
If your virus scanner support exclude directories option, try to use it.
Also Avast and AVG are known of these problems.
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).
Use virustotal if it's something like 3/50 and the "3" are no-name AV vendors let's ignore it, add entired pelles c installation dir to exclusion ;D
