Windows 7: BSOD i think prolific usb to serial

Windows 7 Enterprise x64
BSOD i think prolific usb to serial

Some time ago I started to get BSOD.
I am almost sure part of them related to Prolific USB to serial i start to use.
But i am afraid latest 2 are of some other origin.

I tried different Prolific drivers, some of them do not start to work at all. (840.4 KB)

Any help would be greatly appreciated!

I suggest uninstalling from your system and reboot, see if issue remains?

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
Usual causes: Device driver, ?Memory

Driver: Wdf01000.sys Probably not the real cause.

Relates to: WDF Dynamic - Kernel Mode Driver Framework Runtime

All I can suggest for that is to ensure you have all the latest Windows updates installed.

Driver causing issues:

Refers to: AksFridge driver (Aladdin security products)
Update your drivers here:

I would also suggest you remove Spybot-Search and Destroy from your system and then run:
Run SFC to check the integrity of all Windows 7 system files:

Click on the Start > Type in search cmd
Right click cmd at top and Run as Administrator
Type SFC /scannow at the prompt
(Note: there is a space between SFC and /scannow)

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.
Tip   Tip
Run these tests overnight

Post back any results/observations.
