Apparently, many major sites have been affected by sporadic Netseer issues:
[Google</a> Chrome’s Netseer malware warning blocks websites, company says no virus distributed - The Denver Post](<a href=“http://www.denverpost.com/business/ci_22515730/malware-warning-citing-netseer-blocks-google-chrome-users]Google”>http://www.denverpost.com/business/ci_22515730/malware-warning-citing-netseer-blocks-google-chrome-users)
We don’t deal with Netseer, as far as I know, but it’s possible one of our legit advertisers uses them.
I haven’t seen this myself, despite surfing the site extensively in Chrome.
