I have a copy of Norton Internet Security 2011 (on disc) and I want to put it on my new netbook, but I don’t want to have my netbook slow down because I have too much on it. I noticed that there is a IS 2011 for netbooks, but I really don’t want to spend more money when I already have a way to protect my netbook. Is the IS 2011 safe to put on my netbook? Is there some way to use it and only download what I need? Help?
