Answer:
IF you installed it go into your files and look for downloads the most recent download is what's up there. if its a windows then you need to go into settings-apps then select filter in which shows your most recent. delete the one in your downloads. After that run virus defender. After that then you need to restart computer.
IF it was already there then there is no removing it.
Oh and next time don't install anything without taking 30 seconds to understand what it is.
