Next, install a solid security tool you can trust. For Windows 10, the included Windows Defender program is a competent antivirus tool even if you don't add anything else. That said, you can opt to bolster your machine's defenses by paying for extra software from the likes of Norton, Avast, and many others. While the number of shady programs targeting Apple computers is on the rise, they're still more secure than Windows machines. The general consensus is that macOS is mostly safe from harm, provided you only install programs through the App Store and apply plenty of common sense. That means you should avoid following shady links or plugging in strange USB drives you've found lying in the street.
