Robert,I can confirm that our files are not infected with a Virus.
This is probably due to a false positive from your anti-virus software.
All our files are digitally signed so you can verify that they haven't been tampered with.
If you right click on the file and choose properties, you should see a tab called "Digital Signatures".
If that signature is present and shows Stardraw.com Ltd as the signer, then this proves that the file has not been tampered with.
I suggest that you get fresh anti-virus updates from your supplier.
