Security software comparison sites

As someone who's obsessed with the security of my computer, I am quite astonished when I come across people who don't have any anti-virus software installed on their computer. Usually, these happen to be the newbies who just bought their pc. I have also noticed that even when they do have an anti-virus program installed, a lot of people do not bother to update the virus definitions. 

 I already have a firewall, an anti-virus program and two spyware removers installed. However, I do keep myself updated to compare different software available in the market. It can be a bit confusing sometimes when you have several companies advertising their security software, as the "best". 

 Visiting review and comparison sites can help us in making our purchase decision. The best ones reviews and compare different web security software along with the prices.
