Malware - "youtube IS BANNED"

Yesterday nite, when i think i will going watch youtube and go browser to open it. when all a sudden youtube opened up for a few seconds, and then close and a popup error message appeared.

(title of error message) youtube IS BANNED
"youtube is banned you fool,The administrators didnt write this program guess who did??"
"MUHAHAHA!!"

(The grammar mistakes are intentional.. this is a transcript)
And an audio clip of evil laughter (sorta like as in the message) plays.. now if I try typing youtube in the address bar, IE closes and that same message with the audio clip comes up! I've tried clearing my cache but that doesn't seem to work.

Ppl hv experince about this problem. So they also tried using Mozilla FireFox but it says,

(Error message title) USE INTERNET EXPLORER YOU DOPE"I DNT HATE MOZILLA BUT USE IE OR ELSE..."

And, the error message seems to automatically close after 5 seconds.

How to resolve this problem?Below the solution:-
Run a virus scan and delete any viruses/trojan
THEN, restart and open up in safe mode and scan again.
If worse comes to worse back up your files and re-format.
EDIT; I did some research - this might come in handy.

Here is how to remove the Malware:
When you get the Message:
1. Go to the Task Manager
2. Click on the "Application Tab."
3. Right click on the application that is giving the message and select "go to process."
4 "Svchost.exe" should be highlighted.
5. Right Click and Select "End Process Tree"

If you really wanna get rid of the Malware there is a File called "heap41a" which is located in "C:\heap41a."This is the script in the file"
