I get the same error message. Google has blacklisted donsdepot.donrossgroup.net and there must be an embedded link to that site in the post.
I would say that it's unlikely that there is actual malware present in the link, rather, the site has simply been blacklisted and is now triggering that warning.
I'm running OS X so I felt confident enough to push through to the post (just out of curiosity), and it's just a JPG image which might bounce through DonsDepot... not sure.
Anyway, it seems like a bogus warning to me. But I'm not running a Windows System which would be more vulnerable, so pass at your own risk I guess.
