I worked at Boeing Computer Services 1979 to 1982. They had a gigantic room full of giant processors….the size of refrigerators. Room was probably 100 X 100 feet and it was full. Every year, though, there were fewer and fewer processors. Pretty sure they all got shrunk down so that all of that info fits in the CPU of a desktop or laptop…or hell. Your phone.
I guess it’s possible, but what earthly good would a virus detector do? A virus might not be there one minute, but 5 minutes later the door handle is loaded with them.
