Hi there, I'm having trouble loading certain websites. It suddenly started 2 days ago when Facebook would no longer load, just sits there with a blank screen. Now I'm having trouble loading my gmail account once I've entered my username and password. I've tried to download some online scanners but it looks like all the links that I've tried are blocked or something, they simply don't load. Could something be preventing the better known scanning sites from loading?

Would really appreciate some help because I'm not looking forward to backing up and formatting everything.
