I don’t think infection, but rather it is tracking my browsing activities, which might be implemented by Google Chrome recently, however caught by Avast!
Yeah, I’m getting this pop-up on 70% of the sites I visit – even google search results pages! I’ve done an avast system scan, spybot s&d and scanned with Malwarebytes, and doesn’t look so far as though my system is infected. This is happening both on Chrome Version 26.0.1410.64 m and Firefox 20.0.1 on Windows 8.
This started occuring this morning (I’m on Eastern Time). Just wondering if this is a false positive problem where the web protector has flagged a url that is commonly embedded in many sites on the internet.
Hmm. My Avast just auto-updated its virus definitions a few minutes ago, and after a quick check it appears the b.scorecardresearch.com malicious URL notification is no longer popping up. Hopefully they’re corrected something. Will post again if I notice a recurrence.
