Well, I decided to try them out, here's thier page:
About McAfee System Protection | McAfee Products
I haven't seen any performance hindrances since installing the software, they have identity theft protection among alot of other very good features, they seem to have improved alot, I only run 2.5 gigs of memory and a 3ghz pentium 4, and it all works fast and well. I found the need to constantly manually update mse to keep it current, there would be frequent definition updates, but auto update wouldn't get them until a few piled up.
