Oh p'schaw, you are the troll. Copy CON: can create an empty file, you just don't know how to do it.
An 'empty program' such as a zero-byte .COM file created with COPY CON: is loaded into memory by DOS, and thus attackable by any virus set up with the suitable vector to do so.
5.25" was supposed to be typed 5ΒΌ", duh.
Unexpected disk activity when the machine is idle would mean the virus also hooks the timer interrupt and does stuff in the background, instead of (or in addition to) infecting programs you actively run. Implementing that on an OS not designed for multitasking is certainly possible, but would take quite a bit more than 100 bytes of code.
False. Read more virus code.
I don't care for your conclusions, which are merely fallacious and ill-intentioned. The machine exists, as does the virus, and it'll be in a museum in a month or so, folks will play with it. That's all that matters to me. Your faith in your own knowledge doesn't impress me.
