Many users 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 laugh:

It happens because of "Heap41a / win32.USBworm" which spreads through USB pen drives and removable storage devices. There is a manual as well as an automatic method to remove the virus:

A. MANUAL METHOD:

Follow these instructions:

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 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 goto following keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\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 goto following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\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.

Thats it. After doing all this, restart your system and you'll get rid of the virus.
