Hello everyone! I have a 2 month old HP All in One. Windows 10. McAfee for virus. It updated a few days ago. Just turned on my computer this morning for the first time since then and the opening page keeps reloading. Had my dayplanner on my keyboard, thought that was the problem. After doing a hard shutdown, I kept trying to do a restart. Finally got it to happen. Changed nothing. Can't open files. Did get Google open once. Took me about an hour to get the task manager opened with cltrl + shift + esc. Search boxes aren't working. Suggestions in this age of quarantine and dealing with someone who knows nothing about how computers work? Video of screen is attached. Thanks!
