Win 10 keeps freezing

Have you done a scan with Malwarebytes? Or with any anti-virus prog other than the dreaded McAfee? -- Installed Malwarebytes which found 141 "threats" that McAfee missed. All quarantined. Restart. No change

Look at your processes in Task Manager. Anything there that causes you to say "what the hell is that"? -- Have looked at processes numerous times and nothing appears abnormal (wtf) or hogging resources.

Have you tried copying to that external via some other port? -- Yes, I have two different Ext HD's; same "copying" paralysis occurs with both.

Have you considered reverting to some prior state, as with Windows System Restore or perhaps a previously saved image file? -- This is great... one of the recent Win 10 updates apparently wiped out all my restore points. I didn't make image file.

Have you done anything to check the health of your hard drives? -- Did Windows disc check. Found an error on C drive which it then fixed. Still no change in issue.

whoa, what a crazy deal. Your help much appreciated.

I ran SuperAntiSpyware which found 17 threats and quarantined them. Restarted. Next ran: sfc /scannow. Results: "Windows Resource Protection found corrupt files but was unable to fix some of them. Details included in CBS.Log."

I've tried to paste all the "details" from the report, but they won't paste; keeps crashing browser. But if important, I can paste to a word.doc and post as attachment. However here are the last few lines:

2017-09-17 08:24:45, Info CBS CbsCoreFinalize: AppContainerUnload
2017-09-17 08:24:45, Info CBS CbsCoreFinalize: WdsUnload, logging from cbscore will end.
2017-09-17 08:24:45, Info CBS Ending TiWorker finalization.
2017-09-17 08:24:45, Info CBS Ending the TrustedInstaller main loop.
2017-09-17 08:24:45, Info CBS Starting TrustedInstaller finalization.
2017-09-17 08:24:45, Info CBS Ending TrustedInstaller finalization.

Next I will run dism/online/ cleanup-image /restorehealth, but I want to post this info first before it got lost.

Ran dism /online /cleanup-image /restorehealth. Results: Error: "0x800f081f. The source files could not be found. Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see http://go.mircrosoft.com/fwlink/?LinkId=243077. The DISM log file can be found at C: \WINDOWS\Logs\DISM\dism.log."

This is getting a little too technical for me. I have no idea what this means or what to do. Again, your help much appreciated. Thank you

Note: just restarted computer. Copying problem still exists. Cannot copy at all now from C drive to ext hd. Does not go past 0%. Seems to be getting worse.

A few more notes: This machine originally ran Win 7. I upgraded to Win 10 with a free version that Microsoft still offered. This was several months ago. I'm wondering if the best thing to do would be to purchase a new version, and re-install Win 10. Does this sound like a reasonable thing to do? If so, could you please look at this Win 10 offer I found, and confirm (or not) that this would be a good way to go? https://www.stdwellers.com/products/...dYlGgJD9fD_BwE

Thank you

1) As suggested, I ran ADWCleaner which found & removed three more items.
2) Performed Windows inplace upgrade -- results: NO CHANGE in issue
3) All this time, I've been trying to copy (backup) files from C Drive to Ext. HD 1 -- get to around 17% then crash. Machine then unusable.
4) Restarted, tried copying from Ext. HD 1 -- to Ext. HD 2 -- Copying went great! Fast, no issues.
5) Then tried copying from Ext. HD 2 to Ext. HD 3 -- Copying went quickly until about 80%, then machine slows to halt. Machine then unusable again.
6) Have run disc check on all drives. All report healthy.
7) I'm attaching a screenshot of latest "Problem Reports." Maybe this provides some clues?

Thanks for the help.

I also ran an Administrative Events report which found 493 events, all either "error" or "Warning." (image below). Not sure if this provides clues or not.
