Enable/Disable Task Manager

1) When i try to access my task manager(Ctr+Alt+Del)...it displays message

'task manger has been disabled by ur administrator'..., and also i cant access my registry too..!!
what may have caused this problem....
is it becos of some VIRUS...????
how can i repair this without re installing...?? any particular software??


1: Close the IE browser. Log out messenger / Remove Internet Cable.

2: To enable Regedit
Click Start, Run and type this command exactly as given below: (better - Copy and paste)
REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Pol icies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

3: To enable task manager : (To kill the process we need to enable task manager)
Click Start, Run and type this command exactly as given below: (better - Copy and paste)
REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Pol icies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f

4: Now we need to change the default page of IE though regedit.
Start>Run>Regedit
From the below locations in Regedit chage your default home page to google.com or other.
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main
HKEY_ LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main
HKEY_USERS\Default\Software\Microsoft\Internet Explorer\Main
Just replace the attacker site with google.com or set it to blank page.

5: Now we need to kill the process from back end. Press Ctrl + Alt + Del
Kill the process svhost32.exe . ( may be more than one process is running.. check properly)

6: Delete svhost32.exe , svhost.exe files from Windows/ & temp/ directories. Or just search for svhost in your comp.. delete those files.

7: Go to regedit search for svhost and delete all the results you get.
Start menu > Run > Regedit >

8: Restart the computer. That's it now you are virus free.

it works !!
