Can't open folders

For some reason I can't directly open folders or many other applications. It will attempt to open then i get an error of "Sorry you have a unexpected error from windows explorer"

I can go to start menu and see everything. I can't even open the control panel. If I back door many of these options I can get them to open. All my internet services work fine.

I ran a malware and even did a microsoft update. I did not have this problem until I did the microsoft update.

Which operating system?

Goto Start menu and to your run command and type in sfc /scannow to repair the file, it will check all Windows systems files and fix , you might need the Windows DVD\CD

If you cannot find run command go to start accessories and black box called command.exe and open it or a dos prompt then type in sfc /scannow. It will do the same thing as the above.

Let us now what happend. Good Luck
