I have used Malwarebytes free version many times in the past. But I have always uninstalled the product before depending soley on my ZAES product, because I had read somewhere that only one anti-malware product ought to be operated at any one time. I just downloaded the trial version of Malwarebytes and executed it, without uninstalling or disabling my ZAES program. It appeared to operate without interference by ZAES. Should I be able to operate both these products concurrently, so I do not have to uninstall Malwarebytes each time I use it? If so, can I also do the same but with the Malwarebytes Pro version? Thanks, in advance, for any asistance. Appreciatively, Arbyem
