If you don't believe me, you must report it to your virus checker supplier and ask them.
I was only asking as you just gave me a one liner reply!
I am using PC Guard from Blueyonder so I assume they are using a mature checker as they are providing it for all their premium customers!
Having said that, when I was unzipping your file, when it came up with the virus report, it still extracted your files. I have since checked your files separately and I agree they are virus free. But it does ring some alarm bells when your virus checker warns you of one.
May I suggest you put a note warning clients about the anomaly so they don't go through the same process.
