Many people are facing a common problem, where Orkut.com, YouTube.com and Firefox are blocked in their systems and they get following error with a scary laughing sound:
ORKUT IS BANNED
Orkut is banned you fool, The administrators didnt write this program guess who did??
MUHAHAHA!!
Following is a screenshot of the message:

So here I'm posting a detailed procedure to solve this problem.
It happens because of "Heap41a / win32.USBworm" which spreads through USB pen drives and removable storage devices. I'll tell you a simple method to remove the virus:
1. Open "Task Manager" and goto "Processes" tab.
2. Look for services with name "svchost.exe". There will be many services with the same name. Most of them will have "SYSTEM", "LOCAL SERVICE" OR "NETWORK SERVICE" as User Name but you have to look for "svchost.exe" service which has your currently logged in username as User Name.
3. You'll get approx. 2 services with the name "svchost.exe" which has your Windows username. End Task them by pressing <Delete> key or by selecting them and clicking on "End Process" button. It'll confirm the action, accept it.
4. Now open "regedit" from RUN and go to following keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Current Version\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Current Version\Policies\Explorer\Run
And look for a key in right-side pane with the name "Winlogon" which will have "heap41a\svchost.exe" in its value field. If you find this key, delete it.
5. Now go to following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Current Version\explorer\Advanced\Folder\Hidden\SHOWALL
And in right-side pane, change value of "CheckedValue" to 1
6. Now enable "Show Hidden Files/Folders" option in "Tools -> Folder Options" in My Computer.
7. Right-click on Start button and select "Open". Now open "Programs" folder, here you'll see a folder "Startup". Open it and if you get a hidden file there, delete it. If its not there, then close it.
8. At last open "My Computer" and open C: drive. Disable "Hide Protected System files" option in "Tools -> Folder Options". You'll see a folder "heap41a" in C: drive. Delete it.
That's it. After doing all this, restart your system and you'll get rid of the virus.
PS: Don't forget to format your pen drive or removable storage media which caused this virus infection because it would still contain the virus. If you don't want to format it, then delete following 2 files from pen drive:
microsoftpowerpoint.exe
autorun.inf

Hey vishal i have trick of how to remove pen drive virusu. When u connect pen drive to pc if it shows any program as autorun then open my computer & tyen following command in address bar ur pendrive address followed by autorun.inf means x:\autorun.inf where x is ur pendrive name. now it open autorun.inf file read the name of program which is said as autorun for example dungi.exe . Then go to windows folder copy explorer.exe to desktop. then rename it as dungi.exe & paste in pen drive. Now remove pen drive & again connect it then after opening it just delete dungi.exe & autorun.inf files . Now ur pendrive virus is removed & no need of formet to it. I also have a program named USB VIRUS SCAN. it is also good. goldi7515@rediffmail.com
