I was reading news stories this afternoon on MSNBC when one of its pages triggered a malware warning in Google Chrome:
The website at www.msnbc.msn.com contains elements from the site adrotator.mediaplex.feed-mnptr.com, which appears to host malware -- software that can hurt your computer or otherwise operate without your consent. Just visiting a site that contains malware can infect your computer.
According to Google's safe browsing alert for that feed-mnptr.com domain, it has contained three trojan programs and five browser security exploits. The domain has been used as an intermediary to infect users of Digg, CNBC and MSN.Com.
I can't check without visiting the MSNBC page, which would be extremely dumb, but based on the domain the malware appears to be coming in from a third-party ad service. There was a report Wednesday that the Drudge Report had hosted malware, probably from an ad network.
