I'm running Windows 7: Ultimate

Whenever I open My Documents, explorer.exe goes up to 100% CPU Usage.

Process Explorer shows this O.o



Any more information I'll post.

Try to scan your PC for malware / virus programs.
Do it with Malwarebyte's / Avira (or other anti virus software you got)

*Make sure that these software's are fully updated, and that you're running this scan while you're in safe mode.

I've scanned using Malwarebytes updated, it detected some stuff:

I killed them, still 100%~ when accessing my Documents.
