What company provides the best home security system?

Is there a website I can look at ratings on the top security systems?

There are several good websites that compare anti-virus and security programs:

However, these ratings vary depending on the reviewer. If you want some personal advice, I advise getting Kaspersky Internet Security 2009. This really has everything that you want in a home-secuity package:

I would also advise getting Super Anti-Spyware Pro. This is a very good program, that also has live-protection, and helps ensure that nothing gets past your security and infects your computer.
