How to find and remove the 'mshelper' malware on your Mac

Mac users around the web are reporting that new malware affecting macOS is circulating under the name mshelper. The malware apparently causes a Mac's processor to run near 100%, which could prevent other applications from performing well or, in some cases, at all. Continually running the processor at its maximum capacity also has the effect of draining a Macbook's battery more rapidly which will have an adverse effect on its overall health.

If you're experiencing these problems and think it might be due to the mshelper malware, know that you can remove it from your system. Here's what you need to do.
