Top free security suites

Seth Rosenblatt Seth Rosenblatt, Senior associate editor April 29, 2010

You don't need to pay for your PC's security, and there are currently six excellent free security programs on CNET Download.com that are rated 4 stars or higher. These include the three most popular programs on the site: AVG, Avira AntiVir, and Avast, as well as ThreatFire from PC Tools. There are also two cloud-based security solutions in the group, Microsoft Security Essentials, which replaced the company's OneCare paid suite, and Panda Cloud AntiVirus.


None of them will replace smart browsing habits. For example, Google announced earlier this week that fake antivirus scams account for 15 percent of all malware. So if you get a pop-up trying to get you to download another antivirus program, ignore it. One of these six security will be more than enough to protect most users, although there's nothing wrong with paying for a security program if you feel you'll get better protection.
