HDD Partitions Cannot Be Able To Open By Double Click "Open With" Error

Problem :
Pendrive/HDD Partitions does not open in double click. Cause : It is generally due to a Virus Attack.
Soultion :
* First, you should tell Windows to show 'hidden' AND 'system' files + uncheck 'hide extensions of registered file types' in My Computer - Tools - Folder Properties - View.
* Then, do a search for all files with the name "autorun" (ANY extension) and delete them. Be careful: they may be *anywhere* - in player folders, system32, etc.
* Then you should open the Registry Editor (Start - Run - regedit) and check the following:HKEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/Current Version/WinlogonThe parameter Userinit in the right window should have the following value C:\WINDOWS\system32\userinit.exe. Any additions should be deleted. If your system is installed on disc D, then it will read D:\WINDOWS\and so on...
* Now delete the following key:HKEY_CURRENT_USER/Software/Microsoft/Windows/Current Version/Explorer/MountPoints2. This step should be repeated for ALL users on the computer including the built-in Administrator account. Now reboot the computer and you should be able to open the drives.
