...microphones instead of keyboards? That is, if it is actually true that virus programs in computers are activated by certain keyboard strokes.I don't know,this is just what I was told by a computer repair Woman.

no because anti virus makers would still pay people under the table to make them

No. Viruses are activated when you download or execute infected programs or visit certain web sites. Whoever told you it's activated by keystrokes shouldn't be a qualified computer technician.

no! your voice is input just like a keyboard is input. the computer will just translate it to its own language.

no it would not. Coding will always have flaws, most put in on purpose. If there was an unbreakable system than a government would keep if for themselves.

nope, the antivirus company will just develop more viruses

let me explain you in this waykeybord, mouse, touchpad, digital pencil are the ways for INPUT, you give commands to the computers by using those.when the time comes, when the mics are used, then it will be another way to input data to computer. how the computer works won't change, how we enter the data will change so , unfortunately virus industry will keep on growing bigger and biggerAdditionally, of course viruses are triggered somehow, but it's not JUST by keystrokes but mouse clicks, visiting a web site or downloading a software.
