As you remember in season one Belldandy got infected by a "Heavenly virus" while trying to solve K1s little look problem. So my question is: How did a virus end up in Heaven? 
If they're  supernatural beings I don't expect that diseases are freely spreading through that place, as gods are able to destroy that sort of thing for good [at least Almighty one is able to do that]. 
So what for would they store viruses? For an apocalypse maybe?
