Can't download it on a computer that isn't connected to the internet, download it on a computer that has internet (manually from their website) put it on a flash drive, take it home and update ^^

but also on another note, if you don't have internet, you don't really need an anti-virus because you are only vulnerable to local attacks (people physically getting on your computer and putting a virus or something on your computer from a flash drive).
