There isn't one and they never release one even to us, sorry.
All I can say is various tweaks and the introduction of "Active Protection" where VirusScan dials home for reference if it encounters something unknown, before sending up a warning.
The next year's model may do away with Systemguards (we all hope) & may allow selection of areas to scan using autoscan (we've been asking for years, ever since VirusScan 7), also may allow you to ignore a detection (another thing we've been asking for, for years), but that's all we know.
I do feel that the latest version 9.3 does offer a lighter memory footprint as opposed to originally when I installed it a few days ago and seems so much responsive and does not seem to slowdown the PC and has awesome scanning speeds. It is nice to see a major change in performance overhaul from the version I used 2 years ago which had a lot of problems and caused my Windows installation to crash every now and then. Hats of to the guys for pulling of a remarkable product.
I'm slowly becoming a convert from Norton. I still have 255 days left on my Norton Internet Security 2009 subscription.
There seems to be a paradigm shift in terms of what McAfee is detecting and what Norton ISN'T. There are a few things Norton is doing that are next generation and I hope McAfee takes a few cues from them.
Namely, NIS 2009 only takes up 8 megs of memory. And I LOVE the system idle time tasks, like scanning when you are away from the PC and doing all the other things it does in the background while away.
I haven't bought McAfee YET, but I am using it actively for the trial. There are some things that seem progressive, and yet for some reason McAfee FEELS old. I can't quite put my finger on it, but maybe the presentation and look of it just seems outdated.
Norton is slick and presented very nice, and shows everything at a glance without having to drive down through tabs or buttons.
If McAfee can nail down the memory footprint, and re-design the interface to be more user friendly, and keep up the detection rate, I think they would dominate the field.
McAfee if you're reading this, please get a copy of NIS2009 and take a look at it, although I'm sure you guys have already picked it apart. I want Norton's interface with McAfee's name on it happy Well, you know what I mean.
I reckon McAfee's always been on the ball when it comes down to the footprint and system resources. Speaking from experience, even on low-powered machines, it's sufficiently adept to keep things moving without impacting your work...
