How often to pull anti virus updates from vendors

with two new rapid replicating e-mail worm/script/viruses in the last three
days I think it may be time to reevaluate how often new antivirus files are
being pulled from the AV vendor sites.

it seems weekly won't cut it any more, but is daily enough? 

is hourly a performance burden?

what implications does that have to host based AV (e-mail, proxy, other)?

or clients side AV? if updates came in three hours in a row could the files
be distributed to all your clients that fast, without unreasonable burden on
network performance?

thanks
Mike
