shut off during Full System Scan

[hondacbrrider]

I have a Toshiba Laptop...It has worked awesome for the four years I've had it....But now for some reason it just shuts off when I try doing a full system scan, use the cd drive, or even when I have iTunes running.....I tried Adaware 6 Pro, tried re-installing Norton, and even deleted the iTunes program.. it still shuts off when in the middle of the Full System Scan....
Any ideas would be greatly appreciated.

OK, in order to fix your laptop, you must do one simple step. This has happened to me before, so I know just what to do. Here is the one, easy to do step: buy a new laptop

does the laptop shutdown when being run from the mains lead or just the battery?also i would remove norton and try avg free and zonealarm firewall,
clean the air vents it could be overheating.
