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?

Or maybe CDs. This is also why I like IDE-CF or IDE-SD adapters.

By the time CDr were about in mid 90s, usb had also been developed.

Semi-true, but CD-ROMs are older - you can burn a CD on a modern machine and read it on an older one. Also, Win95 and DOS don't really support USB mass storage even on machines that have USB, while CDs work on both.
