Windows Explorer keeps crashing

Everytime I attempt to click on something on my desktop or taskbar, etc it says
"Windows Explorer has stopped working" but luckily I can double click and open firefox.
Whenever I try to right click something or open an explorer window it says this and gives me this:

Note: I tried to restore my computer to an earlier time but unfortunately I don't have any restore points.

I can't right click anything. I can get to the accessories folder and open it but if I right click something explorer crashes.

I have the same problem. In Windows 7 Enterprise, when I right-click certain folders, Windows Explorer crashes. There's no pattern that I can see where some folders will crash Windows Explorer and others will not.
