Hello,

ClamWin 0.88.4 considers stub_dll_native.bin of the anti-malware program "Prevx1" malware i.e. a "Broken.Executable". McAfee VirusScan does not consider this malware.

Re "stub_dll_native.bin" there is hardly any information on the internet.

Question: Could this be a false positive?

Broken.Executable is not a virus, it indicates an exectable file which does not conform to Windows Portable Exectable specifications. You can safely turn detect broken executables feature off.
