Good , and I was instead talking more generally, since a virus, of all the things that can happen is only one, a software issue/crash, a hardware malfunction are also possibilities, and as said a "container" is a "larger target" for any of them.
If you prefer, a "container" leads to a binary situation 0/1, On or Off, Black or White, data are ALL there or there are NONE.
A more normal filesystem leads to more shades of grey:
http://reboot.pro/to...lack-and-white/
i.e. often it can be partially corrupted (and then it can be partially recovered).
