Most antivirus I tested, even the paid ones, are so annoying with popups and complaining about cracks that I just take the risk and go without em
You’re not going to find an AV that doesn’t flag modifications as virus/malware. That’s kind of the definition of malicious behaviour by a program.
Hell, Windows itself will overwrite changes you make to certain exscutables/dll’s, etc, with its own file protection system.
Test your cracks in a VM. Then use them as needed, or do the cracking in a VM.
