amazing experience would try again

I left my computer unlocked at the dorm I live in and ig my friend thought it would be funny to install this without telling me. So for the longest time I was so confused why I was getting John Cena gifs everytime I loaded up a website. I installed so many anti-virus/malware softwares to detect it but it was just a extension he installed. 10/10 prank honestly and this extension works great.
