It is absolutely not "conspiracy talk" to say that malware steals information from computers. It's one of the many classes of malware out there.
And malware is definitely a danger, but to be absolutely clear, Malwarebytes isn't. It has been a respected Malware removal tool for decades now.
I haven't used Malwarebytes actively in a while since most security suites, including Windows Security, have been folding malware scanning and removal into their functionality.
