Hello,
Can you provide me with AdwCleaner's debug logfile ? Just run AdwCleaner, click on "Options" then "Activate debug mode".
Try running the scan. Even if it does not complete, you should have a file called "AdwCleaner_dbg_xxxx.txt" inside C:\AdwCleaner.
Please post its content in your next reply.
Moreover, do you have this issue only on W10 64b ? Did you try with other versions ?
Regar...
