Updated the video driver using the program you suggested, then tried to run malwarebytes again. MBAM got stuck again, so I cancelled the scan, restarted in safe mode and ran MBAM again successfully. It prompted me to restart to complete cleaning process and it is now taking perhaps the longest time ever to restart.
What did MBAM state that it located, could you post the log
Here is the MBAM Log.
I wonder where they came from as those are bread and butter to adwcleaner
As a clean boot fails to resolve the speed issue my recommendation would be to reinstall windows
I thought that might be coming and frankly was leaning that way anyway.
Thanks for your continued help.
It is the only solution I feel, as a clean boot only loads windows drivers and services, no others are loaded. This would indicate a windows file system problem rather than anything else
