System Crashing - klflt.sys failed

[RetroDee]

Since yesterday my laptop continue to crash to the blue screen when I try open a photo, Word, etc.  Seems ok when I open my browser, which is where I'm sending this from.
Message says klflt.sys failed

Stop Code is UNEXPECTED KERNEL MODE TRAP

I ran a disk clean up and ran a scan via Kapersky last night - all seemed fine.

Any help would be appreciated.
