Any Suggestions

There are so many different types of security programs for computers. I get so confused as to which one does what. For example, I have heard a little bit about the Retina Network Security Scanner that you can install on to your computer. I honestly do not know what makes this one more special than any of the other ones. I need to figure this out, though, because I want to protect my network and I also want to have the best security program as possible. I am very stingy about what I buy or download. If I could get any suggestions, I would appreciate it.
