Choose Your Defender! 10 Anti-Virus Programs Reviewed and Compared
Webroot SecureAnywhere Complete 2012
Floats like a butterfly and stings malware like a 10-pound hornet
You could hear our collective groans from a country mile when Webroot told us its new SecureAnywhere line exists almost entirely in the cloud. Our first thought was, this is going to suck. Webroot proceeded to tell us that SecureAnywhere is like no other antivirus out there: it takes up a fraction of the hard disk space as competing security programs, consumes a minuscule amount of RAM, and can scan a hard drive in seconds, not minutes. All this while still being effective? There’s no way, or so we thought. Astonishingly, Webroot undersold its product.
Installing Webroot’s flagship SecureAnywhere Complete software took less than five seconds and consumed roughly 50MB of disk space. That’s because SecureAnywhere is mostly just a local command hub for Webroot’s cloud database where the bulk of the signatures are stored. With an active Internet connection, you’re plugged in to a constantly updated “threat intelligence network.” Combined with a multilayered heuristics analysis that examines a file’s behavior, age, and popularity, SecureAnywhere is able to detect zero-day and even zero-hour threats, at least in theory.

Webroot has its head in the cloud, and that's precisely why SecureAnywhere is so light and effective.
In practice, SecureAnywhere works as advertised. We tested SecureAnywhere using the default settings and watched in surprise as it intercepted a bevy of threats, both locally and on the web. Against all odds, this tiny program towered like a giant. But what happens when you remove the cover of the cloud?
To find out, we disconnected from the Internet and unleashed a flurry of local attacks. As one might predict, SecureAnywhere stumbled, but it didn’t wave the white flag. When you’re working offline, SecureAnywhere still scans for suspicious activity and is able to block some threats. At the same time, it logs all active processes and tattles to the cloud the next time you’re online. If those processes turn out to be malicious, SecureAnywhere gets to work trying to stomp them out by reversing any changes that were made. It wasn’t quite as effective in our tests, but how often are you both offline and shuttling a bunch of dirty files to your PC?
Extras include a light firewall, cloud backup, a network manager capable of killing offending processes even when you’re cut off from the Task Manager, a customizable sandbox, and a whopping 124 settings to tinker with. Oh, and SecureAnywhere doesn’t conflict with other AV apps, so feel free to double-up with a free solution if you’re paranoid about security. Color us impressed.

Avira AntiVir Personal
Suffocates most malware but isn't quite airtight
Avira’s AntiVir is a favorite for frugal computer geeks. It’s free, it doesn’t gorge itself on system resources, and it consistently performs well in front of the big independent testing labs, albeit not all of them. Both Virus Bulletin (www.virusbtn.com) and AV-Comparatives (www.av-comparatives.org) sing high praise for AntiVir’s detection rate, but the song coming from AV-Test (www.av-test.org) is less upbeat and tells of AntiVir faltering in the face of zero-day malware attacks. After putting AntiVir through our own battery of tests, we feel compelled to join AV-Test’s chorus line.

AntiVir recommends disabling Microsoft's Windows Defender to avoid potential conflicts, but we think it's a risk worth taking for the added protection.
At first, malware had a tough time slipping past AntiVir. Dirty download after dirty download was swept away. It wasn’t until we tried to install a fake AV program that things turned ugly. Rather than stop us from turning our test bed into a pop-up infested mess, Avira blinked, and it was lights out. AntiVir wasn’t the only one to fail this portion of our in-house testing, but somewhere along the line, it also let rogue code ensure that our efforts to click URLs from Google searches were redirected. Our verdict is inevitably going to disappoint staunch AntiVir advocates, and while it blocked the majority of threats we threw at it, the two it missed happened to be big ones.
On the plus side, system performance is virtually unaffected with AntiVir installed, save for a slightly longer boot time. There’s also a fair number of tweaking options, though digging into the settings feels a little cumbersome. Along with AntiVir’s inability to guard against some fake AV software, we wouldn’t advise installing it on relatives’ machines willy-nilly. Computer‑savvy users who plan to supplement AntiVir with smart computing habits and the occasional second opinion from a dedicated antispyware program (or two) should be OK. Faults aside, you can’t argue with the price.
Best Practices
How to avoid getting hit
The best protection against malware isn’t security software, it’s you, the user. You should consider antivirus software as your last line of defense, and if you really want to avoid malware—don’t we all?—you should steer clear of high-risk situations altogether. Here are some tips.
Above all else, keep your software up to date. It starts with Windows but extends to all of your system software, especially programs that connect to the Internet. If you have a lot of programs installed, Secunia PSI (free, bit.ly/DW9u) will sift through them and let you know which ones are out of date. It will even fetch updates for you.
Be extra cautious when connecting to open Wi-Fi networks like the ones you find at coffee shops, airports, and other public places. It doesn’t take much effort for a hacker to set up a fake free Wi-Fi hotspot in hopes that you’ll connect to his laptop instead of the real hotspot.
Whenever possible, try to avoid using someone else’s computer to check your webmail. Can you really trust that their system isn’t infected with a keylogger or a screen‑capture utility? It just isn’t worth the risk. If you simply must, don’t forget to log out.
Finally, check the file extension before you open what you think is a JPEG or some other picture format. We’ve seen dirty executables hide behind picture icons. Right-click and select Properties, or configure Windows to “Show hidden files, folders, and drives” by opening a folder and going to Tools > Folder Options > View.
