Just got this:
Apparently Netseer's corporate web site got hacked. But they also use the same domain to serve out banner ads, so any site that is part of their ad network also triggers the malware warning. (Chome/Chromium apparently use a domain blacklist.)

Amusingly enough, there's a link in that The Street article to another related article on ZDNet; but the ZDNet article (as of right now) is triggering the very malware warning the article is about!
