McAfee Cox Security Suite continually deactivating
My McAfee routinely deactivates itself. I uninstall it (per support answers I've found in these forums), download the latest version, and install it. It's fine for a month or so, and then I'll get a red exclamation point in the icon in the menu bar. I launch the McAfee control panel and it tells me that it has been deactivated since 1/15/17. Doing this every 4-6 weeks is getting old. Is there a solution other than the cycle described above?
MacOS version 10.11.6
Thank you for your time,
