Both of those Installer processes you have running are Genieo installers, each running from a disk image that is mounted as a "disk" on your system. Those disk image files should be in your Downloads folder, or wherever you have your browser set to download files, and would have been something you downloaded, opened the disk image, then ran the Installer app contained in that disk image.

Malwarebytes Anti-Malware for Mac should remove whatever those installers might have installed. But you'll want to make sure those Installer processes are killed first. Kill both in Activity Monitor, then clean out your Downloads folder. Delete anything you've downloaded recently, any anything that you can't identify. Then run a scan with Malwarebytes Anti-Malware for Mac and restart your computer.
