REBOOT
Uninstall anything Java.
When and if a program needs Java, then you will be prompted to download the latest version which is Version 7. All previous versions have some serious security flaws. This is advice from Oracle, the makers of your Java software.
Get rid of all of your anti-virus, anti-malware, firewall software.
The three products you have listed there are trouble sources, especially AVG and the XFinity. Older versions of Norton and the free version are also notorious offenders.
Install and use ONLY MSE, Microsoft Security Essentials.
Link for MSE in my signature.
µTorrent must go while we are diagnosing your problem. This point is not discussable
REMOVAL OF P2P PROGRAMS
There are signs of one or more P2P (Peer to Peer) File Sharing Programs on your computer.
As long as you are using any form of P2P networking to download files, you can anticipate malware infestations.

I strongly recommend that you uninstall:
µTorrent
BitTorrent
Vuze
I've seen where a corrupt media file can crash explorer.
The OP shows DIVX faulting.
Can the file(s) causing the issue be copied to another PC to see if they cause a problem?
Maybe try re-installing DIVX or try a different version?
Did the problem just start with recently downloaded file(s)?
Were file(s) causing issues downloaded via Torrent?

The external drive may have problems.
Why not try running dskchk /r or the manufacturer's diagnostics on the external drive?
