How to remove Microsoft Powerpoint.exe virus or Orkut Virus

Have you seen this message in your computer.

” ORKUT IS BANNED,Orkut is banned you fool`,The administrators didnt write this program guess who did?? ”

Then you are infectedwith the above virus.
The virus, after affecting your computer, creates a folder named "heap41a" in your root drive ie; C drive, where it resides. This folder will be hidden and since this virus disables show hidden files and folders option, it is not easy to locate. This folder contains following:
* Offspring - an empty folder.
* 2.mp3 - a laughing sound.
* Icon.ico - a blank icon file.
* reproduce .txt - codes to change registry entries.
* svchost.exe - gives all kinds of pop-ups.
* script1.txt - codes for displaying pop-ups.
* std.txt - codes to change registry entries.

It will not let you open Orkut using Internet Explorer. It will not let you access even YouTube too.

This is the AHKHEAP Worm

svchost.exe (239,104 bytes)
