Don,
It is a great price, if you get the rebate back, I know a lot of people that have had problems getting them from Symantec and they have the same offer here at Fry's in Texas.
I don't know if you have had good results with Norton's. I know it is the most popular anti-virus problem, but all the machines I have worked on to remove viruses,trojans and worms have had Norton's or McAfee's running and have not cleared them up.
IMHO, there is a totally FREE anti-virus program that I recommend called AVG that detects and removes much more than Norton's & McAfee's and does not hog the system resources that Norton and McAfee use. You get almost daily virus definition updates and can schedule dealy virus scans. Try it, you can download it at the link below.

I use the Professional Edition to clean the machines I work on but there are only a few differences between the Free version and the Professional version that costs $38.95 with 2 years of updates.

I would recommend that all my fellow Chippers dump Norton's or McAfee's and try AVG Free Edition!
