Best Buy carries NAV in the [i]Special Value Edition[/i], which is just a CD in a cardboard sleeve for $20. I asked why the price difference, was told, "Well, the regular edition has a paper manual, registration forms, ect..." These days you can register electronically and the manual is on the CD.
I told them at Best Buy that digitalized info works so well with a digital information retrieval device, a.k.a. the computer.[rolleyes]
The Mcafee is probably on her main OS recovery disk, it came with the bundle, at least mine did for my HP. To have a startup disk for the virus program of your choice, you have to select that option and make one up. Should be one of the first things done with a new computer or virus software.
Hopefully you and your mother know of the old computer maxim, "Blessed are the skeptical, for their files are backed up."
P.S. Check on that Norton site, they may have a fix for this virus.
