It's not detecting a virus or trojan on the site, but malwarebytes has the domain in its protection blacklist. Checking around, so does mcafee apparently, so there may be others(though google safebrowse says its clear.)
This is probably either the result of the fucked version going around and being associated with the site, or some fucker's been reporting it. Would likely have to be taken up with the companies directly.
You should be able to disable the blacklist if you want to, though it's understandable if you don't wanna take the chance. Hop on search and run the site through as many URL scanners as you feel like, and you can make a more "informed" choice about that.
