Personally I feel that antivirus software should be bundled right into Windows. However, I'll assume that past antitrust issues (Internet Explorer) might have prevented that from ever happening.
Luckily today there are several worthwhile free antivirus programs that guard your PC just as well as the most expensive store-bought protection (business security is another matter).
Before you spend another $25-$75 to upgrade to the latest version of Norton Antivirus consider that Microsoft themselves now offer a free download that is just as effective. It's call Microsoft Security Essentials (MSE) and it handles everything a home user needs to stay virus and spyware free. This is a great preventative tool if your PC is not already infected - other tools are needed to remove an existing virus (such as Lucky Leo).
