Three BSODs "caused" by ntoskrnl.exe, all hardware tests are fine

The BSOD is caused by Klif Mini-Filter fre_wnet_x86 (Kaspersky).

Code:

fffff880`03d847c8  fffff880`0365b7e7Unable to load image \SystemRoot\system32\DRIVERS\klif.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for klif.sys
*** ERROR: Module load completed but symbols could not be loaded for klif.sys
 klif+0x237e7

Description here: Driver Reference Table - klif.sys

When an antivirus program is responsible for a crash, it is to remove it to make the situation stable; despite of all its greatness. Uninstall Kaspersky using Kaspersky Removal Tool. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

Also, Athrx.sys is failing here, too. Kaspersky, when failing, makes the network drivers fail, too (sometime it causes storage access problems as well).

Code:

fffff880`03d84058  fffff880`05ac2a75Unable to load image \SystemRoot\system32\DRIVERS\athrx.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for athrx.sys
*** ERROR: Module load completed but symbols could not be loaded for athrx.sys
 athrx+0x6a75

And this driver is kinda old.

Code:

fffff880`05abc000 fffff880`05d72000   athrx    T (no symbols)

Athrx.sys is Atheros network adapter driver; but sometimes the driver is used by some other hardware. If you use any Atheros connection, update the driver from ATHEROS drivers for Microsoft Windows (Atheros?????), by matching the model number.
