Google blacklisted my site today and my server team has found no trace of website manipulation. They believe one of the ad networks is distributing malware. Has anyone had malware issues with any ad network in the last two days? I only use top networks - Casale, Google Adsense, Lijit, Pulse Point (context web) and Sonobi.
So far, according to a few scans, the only codes that continued to flare things up was Context Web and Vibrant Media. I've never had problems with either in the past. Has anyone else experienced issues with either? They could be false positives, I'm not sure, but when it comes to Google doing a blacklist, I remove whatever code is presenting issues.
It is definitely one of the two ad networks and the malware is only affecting certain overseas regions, which is making it extremely difficult to track down. I was removed from the blacklist after removing the tags to ContextWeb and Vibrant Media. I added them back early today and by nightime I was once again getting flagged by Google for malware, and removed their tags yet again. I advised both companies of the issues. Not sure which of the two is the actual culprit. Any advise would help or if anyone else is experiencing this issue.
