Trend Micro AntiVirus plus AntiSpyware is a stripped-down security option, offering only the most basic of protection. That's not a bad thing, but except for the Smart Protection Network, which leverages anonymous data from customers to block malicious threats that are manifesting on users' computers, we're not sure how this differs from its freeware competitors.
There is strong customer service, of course, and the user account-style lockdown to prevent unauthorized changes to programs. However, the program lacks consistent performance, and a lack of recent independent testing numbers on Trend Micro has made it equally hard to determine how effective it is. Unless you're a die-hard fan of Trend Micro, we'd advise staying away from the bare-bones AntiVirus and AntiSpyware version this year.

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.
The LinkScanner feature protects you from third-party code exploits before they load in your browser and for ranking search results. Annoyingly, when you install its optional toolbar, it commandeers your new-tab page, decidedly inappropriate behavior. The program doesn’t obviously tax your system when scanning or when running in the background, although CNET Labs determined that it will significantly slow down your system’s boot time, and slightly delay shutting down. AVG also detected some image files as threats, when two other scans decided they weren’t–we decided these were false positives. AVG might not be the fastest or the most effective free security option, but it still gets the job done and you’re better off with it.

Consistently at or near the top of independent efficacy testers, Avira’s AntiVir remains one of the best freeware security solutions around. Its scans are flexible, allowing the user to fully scan both internal and external hard drives, run a preloaded scan–for rootkits, for example–or customize a scan. The latest version introduces antispyware protections, scanning tech that can crack open “locked” files, improved internal security to prevent AntiVir’s files from being maliciously altered, and one-click threat removal–no more baby-sitting.
There are few interface changes in version 9, and older users are not likely notice anything different in the interface besides a refreshed banner logo. The main window offers a left side navigation with drop-down menus and a central pane for more detailed information. AntiVir opens to the Status menu, informing you of your last scan, your last definition file update, whether the real-time guard is active, and premium upgrade link. Events logs changes to the program and the Reports tab keeps a history of threats. Both are exportable.
The Local Protection and Administration navigation options reveal the Scanner, Guard, Quarantine, and Scheduler features. Combined with the Configuration button located at the top of the central pane, users can customize their scans as necessary. Quarantined file information is on display, with options to scan it again, restore, delete, and e-mail the file to Avira. The rebuilt heuristic engine retains the same choices from the previous version’s, and can be turned on or off in part or in full and offers three intensity levels. The scheduler offers much that other free antivirus programs don’t, and the help features are excellent, with mouse-over information on each feature.
Savvy users will notice the removal of the on-demand e-mail scan, and AntiVir is still challenging to fully uninstall. Despite these hang-ups and the nag screen that follows definition file updates, AntiVir offers such effective protection and a well-rounded set of features that as long as the updates keep coming, it’ll be our first line of defense.

This impressive software provides the same steadfast protection of well-known antivirus programs, yet it’s surprisingly free.
Avast Home Edition guards your PC and the network with multiple shields that scan executables and files. You can select parameters for scanning, and even choose wildcards to exclude specific file types. You can adjust the sensitivity level for the program’s detectors when it comes to scanning downloaded files, instant messages, e-mails, and a host of P2Ps. Its efficient interface opens up window after window to tweak its settings to your liking, for novice to advanced level protection.
Though it took quite some time to run, we’re impressed with this application’s boot-time antivirus scan. Fortunately, if you’re in a pinch you can bypass it. If malicious contents are detected, Avast comes to the rescue with handy virus cleanup tools. Some decent PC controls are even handed out here. You can block certain URLs and file operations, such as writing to files or even renaming, deleting or formatting them.
