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
