On my desktop a txt file appeared titled “I’m watching” with the inner text saying “Always watching”. I was freaked out

Prior to this, my laptop was having what I thought were hardware problems, where it would have trouble starting up and would crash after the screen glitched out and showed a load of flickering squares.

I deleted the txt file and ran Malwarebytes and quarantined all of the files it suggested

Looking back, I haven’t really downloaded anything sketchy in the past while

My current plan is to do nothing and monitor all my accounts unless something else sketchy happens then I will factory reset the laptop and reinstall Windows.

Or should I factory reset the laptop now? The only reason I haven’t is because I haven’t backed up before this and I have a decent amount of personal files I’d like to keep.

Sorry if this is dumb, I know very little about computers
