Cant update yum what so ever [Errno 14] HTTP Error 404 - Not Found

Linux and Unix-Like Red Hat

Hello!!!
I am so frustrated I'm about to snap!!!
I cant hear any sound in Firefox or re-install Chrome.
Every time I try to do anything with YUM inside my terminal (like update or install) I keep getting this error:

failure: repodata/repomd.xml from virtualbox: [Errno 256] No more mirrors to try.

I couldn't post the url but its a stupid virtual box link that's holding things up and then I get this error:

 [Errno 14] HTTP Error 404 - Not Found

I even un-installed virtual box after seeing this message because all my apps in V box has been acting weird. After un-installing VBox this error is still a thorn in my side.

Can anybody please help???

Thank You
AO!!!
