Internet Explorer will randomly not close without help from Task Manager

Greetings wise wizards of EE:

I'm helping a friend who uses a Dell Windows 10 desktop with an i5 Intel Core processor and 8 GB of RAM. Recently, her system... somewhat... locks up, in that randomly she cannot close Internet Explorer by clicking the red square with the white x in the upper, right hand corner of the window. The cursor is not locked up at this time, but she cannot close or open any application while IE is exhibiting this behavior. She is able to pull up the Task Manager via CTRL-ALT-DELETE, and after IE is "ended", her system works normally until this effect randomly happens again, about once per day.

I have run virus/junkware scans with Malwarebytes and Windows defender, and her system appears completely devoid of any Internet threats. I also disabled all non-essential auto-start applications via the Task Manager start up queue, and set her machine to a high performance scheme. I also reset Internet Explorer, deleted cookies & temporary Internet files, ran Disk Clean Up and made sure that no bizarre plug-ins are present.

Short of a system reformat & reconstruction, which she does not want to do, I'm not sure what else to do.

Any assistance in solving the mystery would be most gratefully appreciated.

Many thanks in advance,

Zovoth

Have you tried to remove IE and reinstall it. Also have you looked at the Application and IE Logs in the Event Manager to find if another program is executing or running at the time the system slows down? You can check the system logs as well.

Perhaps consider using another browser.
