"Preparing security options" screen following my PC being slow and unresponsive

Hello, so I was simply watching youtube in my web browser (Microsoft Edge) and I left my PC for about 45 minutes because I had to go to town. I came back and the first thing I noticed was that my monitor took an insanely long time to wake up when i moved my mouse or pressed keys on the keyboard. When it finally woke up, my cursor was very slow, almost unresponsive. I could hardly do anything at all, and every so often a little window would pop up with the title as "Microsoft Windows" and stated "The program is unresponsive. Would you like to end it?" and when I would click cancel it would pop up again on a different location on my screen. Finally I tried Ctrl Alt Del and that is when a grey screen came up with a loading icon and the words "Preparing security options".

At this point I could do nothing at all and was forced to turn my PC off with the power button.
Now, I've booted it up again normally and I am back to normal. The one thing I still notice now is that when I press Ctrl Alt Del, that same "Preparing security options" screen pops up for as little as half a second before displaying the usual Ctrl Alt Del screen options. From what I could find online, this seems to be possible malware? Although I am using my system like normal for the time being, I am afraid that I may be infected with something and could use any help/advice as to what just happened. Thanks

This sounds like a failing hard drive.

Windows tends to perform slower and slower as the drive starts to die.

With the end result being blue screens or refusing to boot.

Assuming the system is bootable next time you turn it on, if you have any files on the drive that you want to save I'd backup them up to a flash drive or external hard drive as soon as possible if you don't already have a backup.

It could also be a virus, but sadly I'm leaning more towards a failing hard drive given the symptoms.
A virus would have been easier/cheaper to fix ...
