Yes, zero day has become the big concern. Please see my previous replies.

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.

In dealing with zip files specifically, I' m wondering what is considered
the "best practice "?  We simply remove the file at our edge proxy, but have
been getting a little flack from a few users.  Our data 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?
