In 30+ years of having computers I’ve had issues twice. Once was on in the 3.11 days. Turned out the copy of KidPix we bought had a virus on the installation disks. The other was in the late 2000s at work on XP. I got got some piece of malware (showed ads IIRC) from a drive by using a Java exploit in an applet showed by an ad network. If you’re not doing high-risk stuff it’s not hard to avoid. But I’m glad MacOS has this built in just in case (like MSE on Windows).
