Well we're probably going to go with Intego. Sophos doesn't measure up because it needs a PC Server to download and distribute the updates, and requires user action to initiate a scan.

A word of warning for people considering using Symantec Anti-Virus 10 for Mac - don't. Please, for your own sake, just don't. It is without a doubt the worst designed and implemented software I have come across in 12 years in IT (and I've supported Lotus Notes). It requires root to be enabled, and has now locked me out of the root account on every one of my 60 Macs. I may well have to manually rebuild every single one, as every method of resetting the root password has so far failed. I have to do this, as since installing it network connectivity has been sporadic at best. Some Macs have grey-screened, some can't connect to servers for no reason at all, some won't even log in. I am genuinely HORRIFIED by how bad this is, and that someone could charge money for it. They have no dedicated Mac support, and I suspect the server implementation was designed by a PC server guy with a diagram of where everything is on a Mac, it couldn't be more poorly laid out.
I am considering legal action against Symantec for the damage their software has done, its going to take me quite literally over 100 man hours to rectify this, and I'm on my own here.
