I need help

Just got a new computer, and it is shiny. I installed comodo firewall and avg immediately, didn't want to catch anything on the web. about 4 days later my computer ramdomly started saying cutie pie, like literally saying it through the speakers, I scanned with Malwarebytes and the only thing that came up was a .dll from my psx and a registry entry from (supposedly) my wpchanger. any ideas what it is and how to kill it?

Please use this thread.
