Warning to delete ''malwarebytes anti malware

Hello  tried reading and understanding what to do about my current NIS popup warming  to uninstall this product - has it actually caused computers to 'crash'? 

              i have the 'free' version that  li do not run on an ongoing-basis so is it 'always' running anway in the background and 'that' is what is causing this NIS popup?

             what i'm asking is:  if i do not 'launch' the program is it still 'conflicting' with NIS?  Settings its  ''scanner'' are ''show do not check for removal  for all three items: pup;pm;p2p.  Is that o.k?  

              Are NIS  users definitely doing the uninstall of the Free program of MAMB?

             Many thanks for advices - Edythe
