Right, but that would be after the 20th or so file came in.
The outbreak flag wont usually fire until you are getting hammered.
That's a day later and a dollar short.
I agree with Jamie. Zero day / Zero hour is the concern.

Is there a settings where it would block zip attachments based on an
outbreak? Normally your AV software should block any zip's with known
viruses. The risk is that a new virus comes out, propogates via zip,
and noe of the AV vendors can identify. In this case, an outbreak
'flag' would block/quarantine all zips temporarily.

shows that nearly 94% of the .zip files that come in via email are
infected so I' m not likely to be convinced to allow them through.
What say you?
