Weird cryptic text pop up after I got spyware'd

This is NOT a tech support question as I already asked that there but more of a I want to know what the symbols are and where it came from, because I've never seen anything like it, the image shown is me loosely recreating what I saw because I didn't get to take a picture of it while it was happening, it's probably just some scary cryptic text made to scare me or smth but it would be help me sleep at night to know where they got the cryptic cypher/text/font from thank you!!!!
