I didn't click 'Answer Now'!!!

(You should note though that such programs only 'run on demand'whereas the anti-malware software that you pay for, either as part of a commercial security suite or on its own, will 'run in the background', meaning that you're constantly protected against malware).
There might also be a few other 'bells and whistles' with third-party security suites (although I'd question whether most of them are actually of any great value to most people).
So you MIGHT get some benefit by buying a commercial security suite (from McAfee, Norton, Kaspersky, etc) but most people can probably get by with:
(a) EITHER Windows Defender OR a free anti-virus program, such as Avast ; AND
(b) EITHER the Windows Firewall OR a 'two-way' freebie, like Comodo Free Firewall ; AND
(c) EITHER a free anti-malware solution (such as AdwCleaner) OR, if they want 'run in the background' functionality, paying for the Pro version of Malwarebytes Anti-Malware.
I'm happy enough myself to use:
(a) Avast as my anti-virus program ;
(b) the built-in Windows Firewall ; and
(c) AdwCleaner for protection against malware.
