Explorer.exe processes leak memory, handles, and CPU

Ever since yesterday, I get instances of Explorer.exe randomly generating and sucking up CPU cycles, memory, and handles. I don't know where it's coming from. But it seems that a couple instances of ctfmon.exe always appear before it happens. I've run AVG, Spybot, and MBAM to try to track this down. I've tried starting the system with only Microsoft services. I'm no closer to a solution.

I can't troubleshoot this one on my own. Help.

Windows 7 64 bit, Gigabyte motherboard.

HJT log included.
