Home Security - Inexpensive Solutions for basic protection
There are a number of great products you can purchase to protect your system. Many of these offer advanced features and conveniences such as autoupdating. Still, many home users don't want to invest in security products that might have an annual maintenance or renewal charge.
In many cases, you "pay for what you get". However in my testing, I've found several great FREE security products (e.g., Lavasoft AdAware SE, Zone Alarm 6, AVG 7, Microsoft's Antispyware beta, etc), that are not only free but top basic products. These solutions might require a little more work as you may not have some of the automation found in premium products. However, they are definitely better than nothing at all.
Most importantly, keep every product on your PC as up-to-date as possible on security patches. It's free and many attacks are based on existing security holes. So updating can make your PC a little more bullet-proof
