I have used for Norton Internet Security for more than 3 years on my PC.
The software is fairly easy to configure.
Also, the protection capability of the software seems really good.
I haven;t had any computer crashes arising out of malware during the time when I was using Norton Internet Security.
It does. however, make the PC a bit slow. It isnt easily perceptible, though.
Otherwise, I would recommend this software for Home use.
