Anti-virus software is a necessity if you're running Windows. There are so many viruses out there, and almost any computer that is running a Windows operating system is susceptible to viruses. It's really, really critical that you have a good anti-virus software installed on your computer. Not only that, but you have to make sure you maintain the anti-virus software by downloading the updates which come out on a monthly basis. Some people have anti-virus software installed on their computer, but they fail to update it and they wonder "why did I get a virus?" That's because at the time when you installed the anti-virus software, it may have been up to date then, but two months later some new virus may have come out, which your anti-virus software doesn't recognize it unless you update it.
