Which A/V are you using? Avast, perhaps? And was the "virus" Win32:Delf-MZG? If so, update Avast and try to download them again. If not, let us know which A/V you're using, and the name of the virus.
Let us know..
The lastest versions of these all have a virus in them and having detected and removed the virus from each none will work anymore. I have uninstalled all 3, but when I try to download them again I am given a warning that your site is a dangerous one. Can you please sort this out as I really need these programs,
