Review:
Avast made great strides in its previous update. Version 5 set the stage for the modern, massively popular, and free security suite with a new interface that ditched a quirky, late-90s jukebox style for a more polished look. Easier to navigate, it also became easier to add new features.
Make no mistake; Avast 6 adds features both big and small. Some that had previously only been available to paid upgrade users are now free for all versions, and newer features have been seamlessly added to the interface experience. If youre familiar with Avast 5, upgrading to Avast 6 wont be that big of a leap.
Installation
Installing Avast is a painless process that compares well against its free competitors like AVG, although--like those competitors--its much slower than installing paid programs like Trend Micro, Kaspersky, or Norton.
Some items of note during the installation that will come up later in the review: to completely avoid the new Windows 7 and Vista desktop gadget, or the new WebRep browser add-on, you must choose the Custom install option and uncheck those here.
Automatic installation of these features is frowned upon, although Avast does provide a clear method for uninstalling them. Its just not as simple as a check box that gets its own installation window, since you have to go through the Customize menu, which makes the auto-install sort of surreptitious.
On the plus side, installing Avast doesnt require a reboot, and using its uninstall tool we detected no remnants in the Registry or on the desktop. Avast has said that the installer has shrunk for all three versions by about 20 percent, although its still a large download at around 57MB for the free version.
Interface
Avast 6s interface is virtually identical to the previous versions. Perhaps the most major change, aside from a slight lightening of the gray in the color scheme, is the removal of the Windows Explorer-style forward and backward buttons. We actually liked those, since they made it easy to return to a previous pane, no matter how deeply into the settings you had explored.
The only other change is the addition of the Additional Protection tab to the left nav area, which hosts the new AutoSandbox and WebRep feature controls.
For users new to Avast, the sleek user interface is a change that came at the end of 2009. The gray-and-orange color scheme stands out well on the screen, and the tab-based navigation on the left makes it easy to navigate between features. Highlighted with the familiar security colors of green for safe and red for dangerous, the Summary tab gives up-to-date info on shield status, auto-updates, virus definitions, the program version, and whether the silent/gaming mode is on. Theres also an unobtrusive ad urging you to upgrade to Avast Internet Security 6.
The Summary tab contains a second submenu, Statistics. If youre curious to see how Avasts shields have been performing against threats, heres where you can get your math geek on. For each shield, it tells you how many files were scanned and when, and presents the data in a concise graph.
The scans live in the second tab, where you can choose and adjust four default scan types plus a custom scan option nestled into the bottom right corner. Real-time shields live in the third tab, and again the clean interface comes into play here as navigating what could be a mess of options and tweaks is instead dead simple. Click on a shield to reveal a real-time chart of what the programs been defending you against, with a Stop button and settings options at the top of the window. Another button at the top takes you to the advanced settings for that shield, and links at the bottom expose the shields history as a graph and export a log file.
Below the Additional Protection tab, which we covered above, the Maintenance tab contains the virus chest and manual update buttons. On the top right of the interface live the Help Center and the Settings, from which you can get much more granular control of Avast. This includes everything from toggling the system tray icon to managing updates to password-protecting Avast access. This is also where you can "uninvolve" your anonymously submitted data from Community IQ, the Avast crowdsourced behavioral detection engine.
One last change: a green Like Avast button has been added to the bottom of the left nav that expedites your Avast-related social networking. Fortunately, its unobtrusive.
Features and support
As mentioned, the two big new features in the free version of Avast 6 are the AutoSandbox and the WebRep add-on. The debut of the AutoSandbox makes Avast the second antivirus option to offer a sandboxing tool for free. Competitor Comodo introduced a sandboxing tool in January 2010. Avasts sandbox probably works differently, as Comodo has a pending patent on its version. And certainly, one of the most frustrating things about sandboxing technology is that there are some indications that it doesnt work perfectly.
Avasts version automatically places programs in a virtualized state when it suspects them of being threats. It walls off suspicious programs, preventing them from potentially damaging your system while allowing them to run. As the program runs, Avasts sandbox keeps track of which files are opened, created, or renamed, and what it reads and writes from the Registry. Permanent changes are virtualized, so when the process terminates itself, the system changes it made will evaporate.
The company hasnt said whether the virtualized state begins after the program already has access to your system, so its theoretically possible that it could be compromised. Theres not a single security feature in any program that hasnt been been compromised at some point, though, so "theoretically hackable" is true of all security features.
The AutoSandbox is different from Avasts paid-upgrade sandbox, and the paid upgrades to Avast Pro and Avast Internet Security include both the automatic version and the older, manually initiated version.
You can access the AutoSandbox settings from the new Additional Protection option on the left nav. It defaults to asking the user whether a program should be sandboxed, although you can set it to automatically decide. Theres a whitelist option for programs that you always want to exclude from the sandbox, and you can deactivate the feature entirel
Avast 6 also marks the debut of the program joining (or succumbing to) the browser-security add-on, with the new WebRep. Security add-ons have a long-standing word-of-mouth reputation for decreasing browser performance, although Internet Explorer 9 Release Candidates impact meter pegs Avasts plug-in at 0.07 second, well below the threshold of 0.2 second that IE uses as the default upper limit for browser performance impact.
WebRep works with IE and Firefox out of the box, and Avast says it plans to release a Chrome version soon. It supports a search result ranking and Web site reputation service that uses a combination of data from Avasts virus labs and user voting to determine a safety score for a site. User voting is a crapshoot for many security vendors, although Avast is known for its vast user base and their passionate support of the program, so the companys plans to give users incentives to vote could easily work in its favor. And make no mistake, Avast fans are truly fanatics: Avast Free has an average 4.5-star rating from Download.com readers, extremely unusual for a program with more than 15,000 votes.
Its important to note that the add-on installs to both Firefox and IE as you install Avast 6. If you dont want it, its surprisingly easier to remove from within Avast instead of from within the browser. Currently, removing the add-on using the browsers interface will cue Avast to reinstall the add-on the next time the computer is rebooted.
Many of Avast 6s small improvements are worth noting as well. The Troubleshooting section now comes with a "restore factory settings" option, which makes it easier to wipe settings back to a familiar starting point, and comes with the option to restore only the Shields settings, leaving other changes untouched, like permanently running in silent mode. Theres a new sidebar gadget for Windows 7 and Vista, and you now can set automatic actions for the boot-time scan. Available under the Scan Computer tab, the boot-time scan customizations give you far more flexibility in managing the lengthy and time-consuming boot scan.
Two features that have trickled down to the free version in Avast 6 are the Script Shield and site blocking. The Script Shield now works with Internet Explorer 8 and 9s protected mode.
Avast doesnt offer an on-demand link-scanning feature, like AVG and Norton do, although the company says that the way that Avasts Web shield behaves ought to protect you automatically from any malicious URLs by automatically preventing the URL from resolving in-browser. A page will appear letting you know that Avast has blocked the site because it is suspected to contain a threat.
If youre running Avast Pro Antivirus 6 or Avast Internet Security 6, the big new feature is the introduction of SafeZone, a virtualization feature that the company envisions people using for secure online banking. The basic difference between SafeZone and AutoSandbox is that the sandbox is designed to allow suspicious activity to run within a safe, walled-off, easily discarded environment, while SafeZone is the opposite. SafeZone creates a secure space that, ideally, prevents threats from getting in
