So, my Kaspersky subscription expires tomorrow and I'm not interested in renewing it. Especially after they snuck a little add-on into Firefox without telling me, and it can't be removed. Even if "disabled", a portion of the code still runs.
I've gotten by with Spybot S&D and occasional scans by Malwarebytes in the past, but what's better? Haven't been brought up to speed on what's effective and what's a waste of system resources.
