AVG Anti-Virus Free Edition

You may think you'll have to fork over a few twenties to get competent virus protection, but that's not necessarily the case. True to its name, AVG Anti-Virus Free Edition keeps your computer safe from the Internet's latest hazards at no cost. Of course, the program lets you manually update its definitions at your leisure, but we recommend enabling the scheduling feature, which will check for updates every day at the time of your choice. Eventually, you might want to pay to upgrade to the Professional version, or you may decide to buy another antivirus suite altogether. Regardless, you should make downloading AVG Free a top priority as soon as your computer is connected to the Internet.
