It's a dangerous world out there, and your computer needs protection. There's nothing new about that message, but there are still people who neglect to install anti-virus software. If you are one of the unprotected, you can no longer claim the expense as a reason not to install some anti-virus software. Download Squad has rounded up no less than 9 free anti-virus programs for Windows.
Each of the programs in this roundup offers commercial-caliber protection. Some of the programs in this roundup offer just 30-day free trials, while others -- such as Avast Home Free and AVG Free are entirely gratis (though there are paid versions you can upgrade to). Personally, I've been a satisfied user of AVG Free for several years, so I'm living proof that there's no need to pay money for an anti-virus subscription when the free version works just as well.
