MSE Will No Longer Complete A Full Scan

When attempting a full scan the program freezes when the progress bar reaches about 1/5 of the scan. Problem began two days ago. I initially uninstalled MSE, went on line to get a new copy, installed it, but no improvement. For years I've run it along side MalwareBytes Premium with no problems. But as a test, I turned off MalwareBytes but this did not help. When MSE freezes it requires a complete system reboot before it will run at all. MSE will complete a quick scan. In the past two days I've run complete scans using MalwareBytes trying to determine if there's possibly a bug in my system causing the problem but it found nothing wrong. Thanks in advance for you consideration.

Per Layback Bear's suggestion I did a ESET scan and it found: "C:\Downloads\System\Sound Editing Software\wpsetup.exe a variant of Win32/Toolbar.Conduit.H potentially unwanted application deleted - quarantined." As a precaution I deleted the Sound Editing Software. I uninstalled MSE, ran a Malwarebytes full scan and it was clean. I uninstalled Malwarebytes, rebooted, installed MSE, ran a full scan and it completed the scan and found nothing. I then installed Malwarebytes and ran a full scan that also was clean. Finally I ran MSE (with Malwarebytes installed) and it completed a full scan that was clean. So, for now, I'm back in business. Thanks to all for the suggestions.
