Windows 7: Computer behaves very slowly when browsing within my User directory

Hi,

Whenever I try to navigate through my user directory (C:\Users\MyName), sometimes it takes ages for the computer to respond. This was happening earlier when I was trying to access AppData so I could fix a GreaseMonkey script.



Once the computer "unfreezes" (it doesn't really freeze, as I can use the mouse and other applications that don't have Explorer interfaces open), it seems that I can browse the same directories unimpeded for a time, but this is a regular occurrence, and something must be wrong, or some service that should be running is not.

I'm fairly proficient with computers, but this has me stymied. Thanks in advance for any help or suggestions.

I would look at any third-party software you have including security software.
