False Positive hit f-secure to our Website

Hello,

We are a self storage company and since two weeks hour website gave and 'unsecure' hit from f-secure. Of course we let our website scanned by professionals, and there is absolute no indication of a virus, adware of other content that infect customers who surfed to our website.

And second, only F-secure gave this hit. None dit Google or any other internet security solution. We know that, because we ask for printscreens and it's al F-secure as program that report the false-positive.

So help me to delete our website from the blacklist of F-secure!! What to do?
