If the are extensions reported by Etrecheck, they may not always be present.

You may be able to boot the machine in safe mode and see if you can delete them with the Finder. Safe mode is shift key held at startup.

Keep in mind, these extensions may be integral part of the system itself, and if you delete those they could lead to kernel panics. Generally speaking you don't want to touch them unless you know they are third party and no longer necessary.
