One concern with this program has always been the amount of RAM it uses while just sitting there monitoring Internet and computer activity. Task Manager on my computer shows it as being close on 200 megabytes. This is high compared to other security programs (AV programs for instance). This led me reading around the Internet about it. The result of this is that I reckon there's often no need to worry about security programs being heavy on computer RAM.
Does it matter how much RAM a program uses providing the computer has a sufficient amount of it? For instance, my computer has 8 gigabytes of RAM. Plenty to run programs with, so does it matter that Malwarebytes Premium is taking up 200 megabytes of it?
The traditional concern about RAM is that the more used by a program running in the background, the slower the system becomes. I don't think this is so however. RAM is there to be
used, not saved (providing you have enough of it). More important would be if a background program activity was using CPU cycles because this
would slow down other tasks that the computer was being used for.
I notice in Task Manager that most programs set to run in the background all take up their bit of RAM but CPU cycles are either minimal or non-existent. This means that programs running in the background won't necessarily slow a computer down.
This post by a Malwarebytes Forum Administrator is what finally clinched the opinion above for me.
