Windows 7 - explorer.exe crash when trying to view files!?

Hello. Today I started my PC without problems...logged in...then I clicked the My Documents button in RocketDock. Something weird happened. I get the error : Windows Explorer Crashed .I tried in Safe Mode and it worked ?! I scanned with Malwarebytes Anti-Malware PRO but only an adware. Restarted and still the same problem . It's annoying because if I want to access my files I need to use Free Commander

You might try this in case explorer itself is corrupted:

SFC /SCANNOW : Run in Command Prompt at Boot

or if you have a Restore Point made before it hit the fan, try using that.

Could be a dll extension that loads images or document previews. What kinds of files are present in this folder?
