These are obviously false positives. The 3 security vendors that flag it as potentially malicious are vendors who do not accept or react to false positive reports, and are known to have a lot of false positives.

Besides, I released my first software in 1998. Ever since then, there has not been a single binary file containing anything malicious that has been signed with my digital signature.
