Given that it's an antivirus company, I'd say they'll be doing
everything they can to get clients to ALWAYS see the very latest
version.

If they wanted to be unhelpful, given they're an AV vendor I expect
they'd be doing User-Agent checks or other irritations to confine access
to their approved clients. Merely preventing caching seems more likely
to just increase load on their servers (lots of people would probably
say "oh, well, I'll download them all anyway) without really preventing
anything.
