I see your point.
So, one has to consider what kind of environment he or she is working with when he or she is trying to figure whether he or she wants to use freeware or commercial software.
My dad uses Norton Internet Security, and he kept boasting how it was the best thing he has ever seen. He saw it at his work, and he decided to use it.
I try to use it, and it's god-awful for my computer: it hogs resources, it slows down start up, and it slows down overall system performance (at least for me). I switch to freeware and I am running well, if not better, compared to when I had Norton on my computer.
