When I try to go on YouTube, it says Bad Request, does this mean I have a virus? Or is it a YouTube glitch?

YOU GOT THE DREADED "BAD REQUEST".

If "your browser sent a request that this server could not understand"

and "size of request header field exceeds server limit", your request

is a bad or oversized cookie. (The same thing is true for "Error 400").

For some very strange reason, it seems 8 of

10 Bad Request messages implicate Firefox.

Simply delete your "Cookies" and everything

will be okay. Don't worry about erasing them;

nothing bad will happen. You won't lose your

internet browser's "Bookmarks" or "Favorites".

The worst thing that could happen is you will

be asked to retype your username/password

when you return to YouTube and some other

websites -- that's all.

As you're dumping your cookies, you should

also erase all your "Temporary Internet Files"

and "History". This will render your computer

totally "fresh" in YouTube's eyes. It would be

best if you shutdown / reboot after doing this:

Internet Explorer 6:

We need more information. When you simply type www.youtube.com in your browser, you're getting this error? Or are you pasting a URL or clicking on a link from an email or other web page?

Which browser? IE, FireFox, Safari?
