What Free Security Programs Can Protect My PC?

You really can protect your PC with free software, but there's a price. Multiple free security programs usually aren't as easy to use as one pricey suite. Your less likely to get decent support (perhaps I should say even less likely). And they lack features like antispam and child protection which you may or may not need. All of the companies that give away security programs sell more feature-rich versions, which come with better support and additional features.
