My mac is saying "Think for yourself, question authority" VIRUS? More things to scare me...?

Question

Okay. I'm creeped out. So I was on my brothers mac allll dayyyyyyy. and then I went to youtube to play a video and noticed my sound was off so I turned it up. I heard the video but louder I heard a monotone man's voice saying "Think for yourself, question authority." It kept repeating even after I paused the video. So then I figured maybe it's from an advertisement so I looked on my two safari windows but there were no ads. So then I was creeped out so I quit out of safari. It continued. I quit out of all applications and it still kept saying that. So naturally I figured creepy virus I'll shut down the computer. So I shut it down and the voice stopped.

So then, with my mom who was watching me from the next room and heard and saw all of that, I went on my home comp and typed in "Think for yourself question authority" in my google search bar.

The first result was this website with a video that I was too scared to watch and pictures of Albert Einstein. MORE INFO IN A MINUTE.

There aren't too many viruses formatted for Macs, but they're out there.

Get an Internet security suite formatted for Mac OS.
