Windows explorer has stopped working.....again and again and again...

I have searched several forums and tried over a dozen fixes for this problem and it still persists.
I'm sure I can safely rule out the first few replies as they seem to be common ones.
So here are the facts:

I dont use IE, prefer firefox.
Am running Windows 7
Have run Avast, Malwarebytes and the free AVG and none of them have helped.
The notification pops up about every 2 minutes.
It happens more than 50 times before it finally stops and the only way to prevent it is to leave my PC on 24/7. (not really an option)
Any restart and the problem starts again.
I can not upgrade to IE 9, it fails to completely install.
I can not disable or remove IE either.
Have had the problem for months.
Looking in Event Viewer i have 28 errors in the last hour.

May an admin please allow me to edit my OP so I can add more details. Thanks.

 

Ahhh thank you! Sorry I should have known that :/

Ok will attach the CBS log I have from my scan, hopefully it means more to someone here than it does to me. I recognise the areas it's pin pointed but not sure what the problem is.
Thanks

EDIT: scratch that, I checked the logs and they had something else since my last scan which stood out. Shall show that first....

please see attachment>>

 

Have now attached the latest scan log.......
shows problems but in the cmd box it says some surrupt files were unable to be fixed.
Thanks for any help

 

Just wondered if anything here stood out as a problem that I can fix.

Thanks

 

Have inserted a screenshot to show the problem and task manager showing the process 3rd from bottom.

Any ideas? Thanks.

 

Have attached the SFCDetail.txt to make it easier to read. Hope it sheds some light. Was advised to do this on the Windows7 Forums.

 

Would a clean install of Windows fix it? Backup my hard drives then install Win7 again??
