Ok, just dropping my two cents in here. Fromwhat I am understanding,
Antigen is sending out a message warning of a virus to everyone on the list
the mail was sent to? If that's correct, let me paint you a little scenario here.

What if I send a email virus out to the entire population/dist. list for MSU?
Can we say exponential chaos? Let me see...every single system out there
wil receive a copy of the virus, and then say it cleaned it and return it
to..every singe system? Hmm..

Better yet, what if I did it like ohhh..8 or 9 times...every hour?

If this is the setup now..it needs to be changed ASAP
