BSOD "caused" by sftfslh.sys

after experiencing my first BSOD i looked into the cause of it, reading several threads in this forum.
i have done the following:
Disc check - turns out no errors
Memory Check - says no errors
Registry errors fixed via norton utilities - i know these programs can miss things
system says the STOP error is caused by a driver - sftfslh.sys
another thread says to delete the driver but i do not know what this driver does and if deleting it will leave windows in an nonworking state.

yes i use microsoft office 2010 and notron 360 v5.0 along with norton utilities v14.0

I have checked the systems files once, nothing came back. i also downloaded the hotfix, the files failed to extract, is there a special way to extract these?.

i will update the post after i try the sfc/scannow a couple more times.

second and thrid time no errors

there are two x64 based files, should i run them both or only one, if so which one

AppV4.6-RDS-KB2517187-x64
AppV4.6-WD-KB2517187-x64

the upgrade patch cannot be installed by the windows installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. verify that the program to be upgraded exsists on your computer and that you have the correct upgrade patch.

that is the message that i recieve when trying each hotfix.

more helpful information:
when the STOP errors started the second time it happend it cleared all documents, music, pictures, and videos.
after that i did a factory default reset then it happend again and i began to look into the cause. so the factory default reset did not fix it.

never thought of it, but the errors didnt start until i installed the driver for a usb wifi adapter, when i ran verifier it picked out the driver as the sftfslh.sys, then i ran verifier without that driver and i still got the screen blaming that driver. in the system logs the wifi always has an issue before it happens aswell.
