I don't know if they are fps or not, but if it was me I would upload each file to Jotti's, where they will be scanned by multiple scanners, and see what the result of that is.

If the results are clean, and therefore probable fps, you can submit the files to ewido for correction:-

If they are not clean, as seems to be the case, you would need to make your own judgement as to whether you want them on your system.
