Instead of replacing Symantec, how about adding another virus scanner?  A
lot of folks on this list use the open source ClamAV (http://www.clamav.net)
and are really quite happy with it.  The ClamAV group is also often one of
the first to get new signatures out.  ClamAV in daemon scanning mode is very
CPU-efficient so you don't really have to worry about performance hits
unless you get an extremely large amount of mail (50K+ messages/day, I'd
guess).

If you have multiple A/V systems scanning your mail message you improve the
chance of stopping both sneaky and new viruses.
