I have Malwarebytes version (Free) installed on 2 Win 10 machines. Automated Scheduling has two entries, Check for Updates and Threat Scan. The former Repeats once every hour and the latter Repeats once ever day. This combination causes repeated appearance on my screen. I have tried "Remove Task" but the screen appears frozen and I can't remove them. Nor can I "Edit" or "Add" them. I've no idea where they came from. I certainly didn't put them there to my knowledge.

Would someone help me get rid of this annoying action?

Thank you.
