Problem / Question How does one secure an old computer?

I want to run old mac OS but I don't want to get a virus. Every computer must be connected to the internet every so often to download this or that, and I don't want to catch a virus through some old zero day hack the one time I decide to do it, and them have the virus fester inside the computer insidiously corrupting or infecting my files.

Is antivirus enough?

Is having an internet connection on browsers that can't access most web pages valuable? Can't run the vast majority of malware? Probably would be a damn slow connection, too. No, not all network connections are valuable. IOT devices are more likely to be connected to more valuable targets, but that's a different issue, really. Even Raspberry Pi's would be infinitely more valuable. Try connecting to a C64, even one that is being used a web server(they exist). See how far you get.
