Answer 1

Hi Verify first whether your system is affected by "TROJAN" or any other viruses

If "YES" Remove the smae by using "ANTIVIRUS" S/W (Preferably AVG !!)

Go to C:\Windows (O.K how to open C or C:\Windows is your questions ..Correct !! MAy be try to right click and use open with option..and select C:\Windows\Explorer.exe OR system may open show openwith window..click on browse and select c:\windows\explorer.exe)

Open REGEDIT file

Find "MOUNTPOINTS2" using Ctrl + F

Delete the same

Repeat the process unless all the "MOUNTPOINTS2" are deleted or If you mess around in the registry, or install some different software packages that add things to the right-click menu, you can end up with a problem where the default action on a folder is always "Search…", even though you set it to something else. There's a quick and easy fix for this problem. Open up regedit.exe by using Start\Run and then browse down to this registry key: HKEY_CLASSES_ROOT\Directory\shell Double-click on the default value and set it to "none" without the quotes, as seen here: This will restore the normal behavior. Update If you are also experiencing this problem when you try to click on a drive, you can run this command from the run box or command prompt: regsvr32 /i shell32.dll This should restore the normal behavior. If you are getting a message that says "Windows cannot find 'PET32.exe'", then at some point you had a virus, or still have a virus. First, make sure that you run a virus scanner to get rid of the virus. Then run the regsvr32 command above, which should fix the problem.
