Most likely your anti-virus is wrong and you would have to file a complaint with them for a false positive.

Just to be sure, check the content of atomic_reference.c against https://github.com/headius/ruby-atomic/blob/1.1.14/ext/atomic_reference.c and see if there is any difference.

yup no change in content. i did what u said and to make it work excluded the conftest.exe from scan.
i m not sure of precise functioning of anti virus, but i hope it does not stop checking any thing vaguely similar coz reporting of false positive.

thanks a lot. 👍

I'm going to mark this invalid, since there's nothing shipped in the gem that should trigger a virus warning. It's likely (as @zimbatm stated) that the built binaries just happen to match a virus marker in your detector.
