As much as I hate to say it, if you're running Microsoft Windows then spool up Microsoft Defender. Honestly, it's just as good at detecting, blocking, and removing malware as any other product, has a much lower footprint in your system thus running cleaner, and is no extra cost. Just run Defender.
Whatever you do, don't spool up McAfee. Sure they sound good and have a good sales pitch but the product is a resource pig. It'll turn a mid-range workstation into molasses-slow dogcrap and low-end workstation into an electricity sucking paperweight.
If you're philosophically opposed to having a Microsoft mono-culture then I've had good luck with Avira but also like AVG and Kaspersky. Of the non-Microsoft options, I prefer Avira.
But, honestly, when I set up Windows workstations for my family members who stubbornly refuse to see the superiority of Linux, I just enable Microsoft Defender.
Peace favor your sword,
Kirk
