Without going into too much detail, my Idea regarding Alien is that you basically have two "bodies" - the regular, human body, which the Alien corrupts and destroy via the classical chestburster, and then the ship as a second/body shell - the ship normally protects the humans from the vacuum and cold of deep space, but the Alien turns the entire thing around by hiding in its many corridors and gutting the crew one by one.
I also considered the thing - in this case, the body that is corrupted and destroyed by the Alien still could be argued to be a biological one (given that the Alien still uses human bio-matter to create its puppets), as well as the human society proper, as it sows distrust amongst the human survivors - each of them sees the others as a potential Thing.

Except the one that is The Thing, who has got to be thinking "humans are idiots!".
Makes sense in that context, and adds a little more wiggle room for movie suggestions. Given your new information I'd add "They Live" to the list. It doesn't necessarily deal with impregnation/infestation (unless you count an invasion as an infestation), but it is about turning people in to puppets using mind control which could be seen as a sort of "corruption".

Thanks! I'll have a look into that.
