Avira AntiVir Personal - Free Antivirus 10.0.0.561

AVG Anti-Virus Free Edition 9.0.730

AVG Free provides the bare necessities when it comes to security, but that should be enough for savvy Windows users. You'll get a combined antivirus and antimalware engine, LinkScanner, and e-mail scanning. AVG Free 9 introduces a few new features, with improvements focused on performance, including claims of faster scan and boot times. One new feature is the Identity Theft Recovery Unit. Only for users in the United States, ITRU is a business partnership with Identity Guard which provides "consumer identity theft solutions," accessible only from the AVG toolbar in Firefox and Internet Explorer.The interface is nearly unchanged from the last version, and generally it's easy to use. From the main window, though, you must double-click to get further information on any feature, whether virus scanning, LinkScanner settings, or updating. Streamlining this to one click would be helpful. A scheduling utility automates both scans and updates, while the upgrade ad at the screen's bottom can be easily hidden using the Hide Notification button. When starting a scan, a slider makes it easy to jump between Slow, Automatic, and Fast scans: the faster the scan, the less comprehensive it is, so users should take advantage of the scan optimization that is recommended during installation to speed up that first scan. A progress meter for regular scans would've been useful, though. Should a virus create serious problems, AVG creates a rescue disk to scan your computer in MS-DOS mode.
