BSOD Windows 7 6.1.7601.2.1.0.256.48

I was checking your crash dumps .... and I got stuck here.

Code:

BugCheck 1E, {0, 0, 0, 0}

*** WARNING: Unable to verify timestamp for spey.sys
*** ERROR: Module load completed but symbols could not be loaded for spey.sys

Probably caused by : Pool_Corruption ( nt!ExDeferredFreePool+100 )

Followup: Pool_corruption
---------

I am not aware about it. So searched ... and got nothing. Even there is no trace of this driver in your system too.

Smells bad now! Scan the system for possible virus infection with the following programs.

• Anti-rootkit utility TDSSKiller
• Windows Defender Offline

There are some other things to be noted, some drivers needs update, but only after making it sure that the computer is not infected.

Let us know the results.
