We currently use Symantec Corp AntiVirus V11 on our SBS 2003 network. No problems with it that rate a mention. Now we've been offered an upgrade to Endpoint Protection. I downloaded the product (huge downloads BTW) but am reluctant to install until I know more about it's pros and cons. Anyone out there have experience with the upgrade on a SBS 2003 network? Recommendations? We are a 20 user network with heavy use of Sharepoint and Exchange.
