Yeah but antivirus software doesn't pick up zero days, which is what you should really be concerned about.
I had some Chinese radios a few years ago, they were proper radios that you could program for all sorts of stuff. I had the software on a USB stick, then plugged it in about 5 years later - pinged up with all sorts of viruses that weren't detected previously.
They don’t pick up anything that they don’t know about, so once the zero day is known the antivirus/malware can find and remove it I thought.
They don't catch zero-day exploits, as those are vulnerabilities in programs that were discovered to be used in the wild. They will eventually catch the malware dropped through those exploits, though.
