R u guys running any type of Firewall?? Cause that has stopped the virus from comin in for us. We also run Symantec Corporate and it does the job every time. It detects all viruses since it updates every few days and if an email comes in to one of the workstations, the user gets a warning when he/she tries to open the contaminated email. Symantec automatically quaratines the virus and all the user has to do is delete the email. I don't think that u guys would have to do all that just to prevent viruses, but a few more pieces of software that will protect u guys will be better. A hefty firewall, and a hefty AV would be ok in my opinion.
