Thanks!
The attached DMP files are all of the DPC_WATCHDOG_VIOLATION (133) bug check.
This bug check indicates that the DPC watchdog executed, either because it detected a single long-running deferred procedure call (DPC), or because the system spent a prolonged time at an interrupt request level (IRQL) of DISPATCH_LEVEL or above.
-----------------
You have two antivirus suites installed (as well as IObit), this is causing NETBIOS conflicts and file system corruption.
1. Remove and replace AVG, IObit, AND Norton with Windows 8's built-in Windows Defender for temporary troubleshooting purposes as they are likely causing conflicts:
AVG removal - http://www.avg.com/us-en/utilities
Windows Defender (how to turn on after removal) - http://www.eightforums.com/tutorials/21962-windows-defender-turn-off-windows-8-a.html
AFAIK, there's no removal tool for IObit, so just remove it via the Control Panel. Also, you may be interested in reading that IObit steals intellectual property - https://forums.malwarebytes.org/index.php?showtopic=29681
2. Uninstall Smart Defrag.
