I've scanned it and nothing obviously nasty found. Of course if someone has put something specific in there you can't tell but that's not really much different from most copies of WIS or EPC. I have some that I know are clean as they were taken from a genuine Saab borrowed disc but given most people have to resort to a download there's no way of confirming the integrity of the download.
I'd still suggest running it in a virtual machine though.
