Can't open C and F drive

Hello SIR,



I am unable to open drive c and f in my laptop though I have already removed autorun by referring your tips [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
Userinit=userinit.exe,autorun.exe

(To correct and solve this error, follow this steps:

Run Task Manager (Ctrl-Alt-Del or right click on Taskbar)
Stop wscript.exe process if available by highlighting the process name and clicking End Process.
Then terminate explorer.exe process.
In Task Manager, click on File -> New Task (Run).
Type "cmd" (without quotes) into the Open text box and click OK.
Type the following command one by one followed by hitting Enter key:
del c:\autorun.* /f /s /q /a
del d:\autorun.* /f /s /q /a
del e:\autorun.* /f /s /q /a

c, d, e each represents drive letters on Windows system. If there are more drives or partitions available, continue to command by altering to other drive letter. Note that you must also clean the autorun files from USB flash drive or portable hard disk as the external drive may also be infected.

In Task Manager, click on File -> New Task (Run).
Type "regeditÃ" (without quotes) into the Open text box and click OK.
Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Check if the value name and value data for the key is correct (the value data of userint.exe include the path which may be different than C drive, which is also valid, note also the comma which is also needed):
"Userinit"="C:\WINDOWS\system32\userinit.exe," )

My problem is still existing. You are requested to kindly advice me to solve this problem../////
