I've found that virustotal quite often marks programs made with FPC as
having viruses. Usually one or two of the checkers there (and avast
sometimes is one of them). Messing with compiler flags (like how DLLs are
being used) tends to make them go away.

You can download an ISO with Windows directly from Microsoft, put it on a
VM like VirtualBox, install FPC, make a small program, upload it to
virustotal and have some of the antiviruses there tell you that there are
viruses on the program :-P
