Trouble downloading Free ATT McAfee virus protection to laptop

I believe I need a CD with the McAfee "Slazenger 300" version of McAfee virus protection in order to download to my laptop the free virus protection provided by ATT. The sooner the better. It is impossible to do on line at att.com/ISS - "page not found". I have an HP EliteBook 8570 with loads of disk space, 8Gigs RAM and an i7 3740 @ 3.0 Gb, and a 500 Gb SSD.
