Good day to all, I really don't know what to do, I've ran about five systemwide scans with the antivirus and nothing pops up, cleaned and edited the Registry, and resetted the router and I still get this screen when going to Facebook.

I really would like some help please
I'm sure it's a virus because I already updated the Flash Plugin, and I also get this screen when trying to enter Youtube. And it happened suddenly, first I lost connection, and when it returned I couldn't go back to Facebook.

I really would like some help please
