It just happen to me while in this thread. Law Firm of lawrence Landshroker and associates ad was up.
Yea I'm getting this occasionally as well. These "ads" are taking over the site, and it's making things difficult.
While I've had the malware warnings, I just got a new one after trying to visit the site. As the main page was loading, I was taken to some site with "armyprotection" in it and the site itself was decked out to look like a virus scanner in progress, despite the scanners I have being AVG and Super Anti Spyware. Quickly closed my browser. First time that had happened, though.
This happened to me. I had to shut down Google Chrome.
