just... 100

they corrected below

It kills exactly 100. No more. No less.

It kills over 100 so killing 100 would be physically impossible for the product actually

It can't kill over a 100 because there's only a 100. No more, no less.

"kills over 100"

I think its supposed to read kills over 100 viruses or something like that, but hard to say, probably a misprint
