*** WARNING: Unable to verify timestamp for avgidsshimx.sys
*** ERROR: Module load completed but symbols could not be loaded for avgidsshimx.sys
Probably caused by : Pool_Corruption ( nt!ExDeferredFreePool+312 ) Code:
Usual causes: Device driver
avgidsshimx.sys seems to be a driver which is causing the crash, and linked to AVG, therefore I suggest uninstalling AVG with the offical installer (see link below)
Uninstall AVG: Code:
Start Menu\Programs\AVG
Uninstall Spybot - Search & Destroy: Code:
Start Menu\Programs\Spybot - Search & Destroy
The later editions of AVG have been known to cause some stability issues with Windows 7, furthermore I would suggest uninstalling Spybot, as AVG and Spybot are both real-time protection programs and therefore are clashing with each other and producing crashes.
You can run
full scans with MSE and Malwarebytes:

Remember to install the
free version of Malwarebytes not the
free trail; untick the free trail box during installation. Microsoft Security Essentails has proven to much more stable and less problematic within Windows 7, than other AV suites available to use. Remember to
update the security definitions for both MSE and Malwarebytes
before scanning your system.
