Of course there's nothing suspect in the FDC files!! Do you honestly think I've written some viruses and hidden them amongst the installation and then openly tell people to turn off their AV when installing just to infect their machines! How absolutely absurd and quite frankly darn right insulting!!!
FDC was first released around 15 years ago so I would have thought I'd have been found out by now, don't you?
AV programs these days are reporting false positives all the time. They scan for certain signatures in the executables and since my programs, like many others, are scrambled and compressed before release it is likely such signatures are replicated during that process. That's NOT to say they have an embedded virus!!!
My own AV complains about my own programs sometimes and I have even known it to remove certain supporting files... telling ME they are infected, hence my instructions to turn your AV OFF when installing and then to configure it NOT to scan the FDC folders. If you don't wish to follow my advice and continue to have issues then I'm afraid I can be of no further help to you.
