Hello.

I am using the internet when out of nowhere, a "You are not authorized to view this page" error pops up on youtube.com. It happens if I go back and click another video, and it happens with every video I have visited. It is 8:25 PM right now. I really don't know why this is happening. I have 2GBS RAM, 250GB HD, and my internet has been working ever since I got home. It started around 8:10 PM. Anybody know any computer viruses that do this or anybody have solutions? I had a look at my proxy's and my hosts. My SpyBot Search & Destroy has it's list preloaded hosts list. The following Mozilla Firefox extensions I use are Archive 404, NoScript, Symantec Threat Level, Greasemonkey, DownThemAll, and Web Developer. The version I use is 2.0.0.13. Does anyone have any answers?

P.S. My ISP is Bell.

You might check parental controls settings, that might be causing it.
Also Content Advisor.

Don't have parentals.

From another post it was suggested that no script might be causing it.
Try disabling or removing see if that helps.

Tried, didn't work. But thanks.

Can you view them with another browser (IE, Opera, or Safari)?
