Editors' Review

+

Looking to compete with both paid and free security suites, Avast wants to create a unified approach to your computer security. Long gone are the days of the quirky interface. Avast is accessible and robust, with an impressive list of free features and strong, though hardly stellar, performance benchmarks.

Installation
Avast has improved its installation process so it's faster than before. It's not the fastest on the market, not by a long shot, but a standard installation took us about three minutes -- around the same as last year.

Some items of note during the installation that will come up later in the review: To avoid the Windows 7 and Vista desktop gadget, or the WebRep browser add-on, you must choose the Custom install option and uncheck those here. Firefox and Internet Explorer will all block WebRep from installing by default, but it may be easier for some to cut it off here.

Automatic installation of these features is frowned upon, although Avast does provide a clear method for uninstalling them. It's 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.

Also during the install, you are opted into Google's Drive desktop manager. If you're a Google services addict, this is a good reminder to get the client app. If not, well, it's a small piece of bloatware to uninstall later. Such are the installation blues.

Unlike last year, installing Avast once again requires a reboot. Still, the uninstallation process left no detectable traces on the desktop or in the registry.

One installation option, available only from the custom install menu, lets you sideload Avast as a secondary security program to supplement your main one. We're not big fans of this option from a security point-of-view, because it can bog down your system resources without actually making you safer. However, as a way to see if you like Avast, it's not a bad thing as long as you remember to choose one security suite to go with.

Interface
After three years of nearly identical interfaces, Avast 8 brings an entirely new suit of clothes with it -- sort of.

While the underlying submenus and settings screens look and feel similar, there's a new home screen that emulates the Windows 8 blocky tile-and-icon style. A colored status box on the left lets you know in green or red whether you are secured or not, while six tabs to its right give you access to the suite's security features.

These tabs provide quick access to specific features: Scan, Software Updater, SafeZone, Browser Cleanup, AccessAnywhere, and the Market. With two direct links from the home screen, Avast is really pushing the market idea, which is basically a landing page from which you can purchase additional Avast-branded tools such as a password manager, data backup, or download the free Android and Mac suites.

At the top of the home screen are links to Security, Maintenence, Market, Recommend, and Support. Account and Settings access lives to the far right of them. The Security tab is the most important one, and gives you access to Avast's numerous shields, as well as a list of subcategories on the left nav: antivirus, anti-spam, firewall, software updater, and tools.

One smaller but noticeable change is that the free version now decorated with a white background, to separate it from the dark-themed paid upgrades. Yeah, it's a color scheme change, but since most of Avast's customers use the free version, it's a noticeable one.

Overall, the new interface is more user-friendly, and that's a plus. The workflow behind the touch-friendly large icons makes it easier to go directly to key features, such as Avast's popular shields, and much of the jargon has been replaced with more easily understandable terms.

It still runs in Windows 8's desktop mode, so it's not a true Metro-style app, but it has that look.

Features and support
Avast 8, comparable with the 2013 version of competing suites, includes several new features that directly affect your security. Changes to existing Avast features include increasing the number of virus definition file updates per day, from 20 or so in the previous version to more than 70 per day in version 8. When running on battery on laptops, Avast will automatically disable scans until the device is plugged in, and the suite now offers full IPv6 support.

Like both the paid and free competition, Avast has a file reputation system for evaluating downloads. The browser add-on WebRep for on-the-fly site evaluation that also checks for fake site certificates is lighter on your browser than competitors' heavyweight toolbars.

The free version of Avast is arguably the most comprehensive set of freely available security features on the market. There's a reason these guys have more than 170 million active users (at the time this review was written). The antivirus, antispyware, and heuristics engines form a security core that also includes multiple real-time shields. Along with the new features, it's got Sandbox for automatically walling off suspicious programs; a full complement of shields that guard against scripts, P2P networks, instant messaging, and potentially dangerous program behavior; a silent/gaming mode; on-demand boot scanning; and a healthy output of statistics for the data nerds.

Avast's Sandbox, by the way, 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, the 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 hasn't said whether the virtualized state begins after the program already has access to your system, so it's theoretically possible that it could be compromised. There's not a single security feature in any program that hasn't been been compromised at some point, though, so "theoretically hackable" is true of all security features.

But it's the new features that drive interest in the suite, and this year's got some very interesting improvements and one dud. The new Software Updater tells you when your programs are out of date, but it doesn't leave you hanging. It provides links to update them directly from within Avast.

This includes known security vectors such as Java, Flash, QuickTime, and PDF readers. In the free version, the updater will automatically download the software update, which then opens its installer. It still relies on user interaction to complete the install, though. In Pro and Internet Security, you get a one-click update that downloads and silently installs the update. The Premier version removes the requirement for any user interaction whatsoever -- updates happen automatically and silently.

The new Browser Cleanup tool is available as a standalone download that doesn't require you to use Avast, but it also comes baked into all versions of the suite. It checks the internal storage and registry of Internet Explorer, Firefox, and Chrome, searches for plug-in and toolbar references and helps you uninstall them.

Two entirely new features do the most to differentiate Avast Premier from its siblings. The suite includes a Data Shredder to ensure that deleted files and folders are unrecoverable using "conventional" techniques. It offers the industry standard three shredding options: a random overwrite, which overwrites files a user-specified number of times with semirandom bytes; a Department of Defense standard of overwriting; and the Gutmann method, the slowest of the three but the most secure.

You'll also be able to wipe only free disk space of remaining instances of data, or wipe an entire partition including on solid state drives, creating some nuance to its deletion options.

It looks like last year's Remote Assistance feature, for single-instance, friend-to-friend remote tech support, has been overhauled and turned into the new AccessAnywhere feature, the second Premier-only feature. It requires you to have Avast on both ends, which wouldn't be so bad, but the installation process for Avast is not as simple or fast as the installation for programs that focus on remote access, like LogMeIn or TeamViewer. Avast's installer alone runs more than 100MB, and the Avast requirement -- as opposed to gaining access through your browser -- hamstrings its utility.

Data shredding and remote access are interesting, but just not enough to get us to shell out for Premier. And sadly lacking from Avast 8 are any tools to directly address privacy concerns, a security issue which will only continue to grow as advertisers, network providers, and browser makers squabble over personal data collected and collated on people using the Web.

Avast also doesn't offer an on-demand link-scanning feature, as AVG and Norton do, although the company says that the way that Avast's 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.

Avast has plenty more nifty extras to help you out. 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.

While these tools are clearly nonessential, and some of the prices struck us as high -- $10 for a Rescue disc? $50 for an annual backup service? -- we like that Avast gives its fans a chance to stay in its ecosystem. The Avast EasyPass, for example, is an Avast-branded version of RoboForm's premium password manager and is well worth the $9.99 annual fee.

In a day's worth of testing, none of the new features appeared to cause any negative impact on computer or browsing performance. Assuming these technologies work as advertised, your computer ought to be a fair bit safer from malware than it would without them.

Performance
Avast was generally well-received by the independent testing organizations, AV-Test and AV-Comparatives.

AV-Test.org gave the previous version of Avast a passing rating in its most recent test, on a Windows 7 computer from December 2012. Avast 2013, the suite's name for version 7, passed handily with a total score of 14 out of 18. A year before, Avast 6 struggled to pass, hitting the bare minimum of 11. Avast 2013 reached 4.5 out of 6 in Protection, 4.5 out of 6 in Repair, and a 5 out of 6 in Usability, for a total of 14. Usability includes testing for false positives.

AV-Comparatives.org also saw room for improvement in Avast during December 2012. The suite blocked only 95.5 percent of threats tested during that month, but then you could kick those up to a more respectable 98.7 percent with some settings tweaks by the user. This user-dependent margin of around 3 percent to 3.5 percent was consistent throughout the year.

Basically, AV-Comparatives found that Avast will keep you reasonably safe, but significantly safer when you turned detections and blocks up high. The testing organization gave Avast its Advanced certification in both the first half of 2012 and the second half, a marked improvement from the lackluster Standard certification in the second half of 2011.

Note: All tests measured in seconds, except for Cinebench. On the Cinebench test, higher numbers are better.

CNET Labs system performance benchmarks show Avast 8 as being fairly middle-of-the-road. It's weak on startup time, generally adding 10 more seconds than average. Shutdown time impact was a bit faster than average, while virus scans were quite speedy and faster than many paid-suite competitors. Avast 8's footprint during common-use tasks such as MS Office performance, iTunes decoding, and media multitasking was average, as well. We'd like to see a much smaller hit on startup times, but other than that Avast 8 Free offers a reasonable trade-off. Avast 8's paid upgrades, however, could do much better.

As far as Avast's impact on system performance goes, in a real-world test Avast completed its scans in a timely yet not blazingly fast manner. A Quick Scan averaged about 28 minutes, slower than last year. The Full Scan averaged to 73 minutes. RAM usage was surprisingly light, with Avast only eating up about 16MB when running a scan.

Judging from these results, Avast has righted some of its benchmarking wrongs from the previous version, but we may adjust that judgment when CNET Labs' scores come in.

Conclusion
When it comes to your security, Avast 8 gets a lot right. It's got a usable, uncluttered interface, solid although not stellar benchmarks, and a set of features that keeps it at the forefront of Windows security.

We'd like to see the innovators at Avast HQ in Prague tackle the real privacy concerns of the modern Web, and the unimpressive AccessAnywhere keeps us from giving the Premier suite stronger marks.

Avast Antivirus 8 Free, on the other hand, continues to be a stellar choice for free Windows security, and we enthusiastically recommend it. Few people want security that turns a good machine into the malware equivalent of Swiss cheese, and on that count, Avast has your back.

"Finally #1....Deserves to be ranked #1 on CNET's list"

December 19, 2012  |  By AntivirusGeek

 |  Version: Avast Free Antivirus 7.0.1474

Pros

+Fast Updating
+Fast detection and blocking of threats also internet connection is aborted when a threat is blocked for maximum security.
+Sandbox
+Light on system resources
+Excellent protection from all 8 shields.

++Avast is so much better than AVG who tries to imitate Avast but is a failure. When Avast compres to Avira, it demolishes it since Avira free only offers system protection and not web protection unlike Avast.
Avast is the best free roubust protector for your system!!!!!!

Cons

None at all.

Summary

Avast detection rate on malware in the system is slightly higher as Avira or AVG (by about 3%)but Avast auto sandbox isolates the suspicious item automatically so no harm is done to the system. Also Avast new cloud feature automatically submits the suspicious item to their labs while keeping the file in the sandbox.This is done in the background so the user is not aware until the result has been made. Finally Avast web protection blocks 96% plus based on AV- COMPARATIVES. WEST COAST LABS and AV-TEST. AVG and Avira can't compare to the high quality standard set by Avast when it comes to PROTECTION and DETECTION as well as PREVENTION....

Always choose Avast

"USED to be good, now its just JUNK.windows 8 uses avoid"

December 18, 2012  |  By kyle3389

 |  Version: Avast Free Antivirus 7.0.1474

Pros

Great security, when its working. The safezone and sandbox modes are kinda cool.

Cons

DOES NOT WORK WITH WINDOWS 8. Blocks random websites. Uses lots of CPU(60-80%).

Summary

I recently got windows 8 on my computer and re-installed avast onto it, it used up about 60-80% of my computers CPU at all times causing it to be very slow. Also it would block almost every other website FOR NO REASON! unless i disabled the shields but that's not safe.. i contacted support and they sent me one email, i emailed them back and never got any responses back! Avast used to be the best not it sucks! I'm sticking with AVG for now on.

Before when i had it on my windows 7 o.s. it used to run great.. but now that i have windows 8 its all about AVG! sorry avast but you let me down.

"Nag nag nag"

December 17, 2012  |  By acord01

 |  Version: Avast Free Antivirus 7.0.1474

Pros

If you'd asked me six months ago? This area would have been full and the one below it would have been empty. Now? Not so much.

Cons

*Used* to be good AV software.

Now it's slower than hell and letting Firefox scan your downloads automatically with this results in lock-ups. Worse, it's consistently popping up with nag messages on the free home version to buy the pro version now. That's COMPLETELY UNFORGIVABLE.

Summary

Nagware that will interrupt every forking thing you do. Don't download it - you'll regret it.

No matter what I tried, this software that I paid for blocks any access whatsoever to my usb Verizon 5 spot 3G modem. It also installed Google Chrome without permission.

Summary

I had to uninstall it to access the internet.

"Potentially Lethal"

December 12, 2012  |  By sakulin

 |  Version: Avast Free Antivirus 7.0.1474

Pros

Attractive format and free.

Cons

The current version of Avast Free comes bundled with Chrome with no permission asked. It slowed my computer to a crawl with constant error messages while using either Firefox or Explorer. I uninstalled Chrome and even with the browser removed coninued to get Chrome Script error messages. I removed Avast and replaced it with Avira Free and my problems were resolved. Use this product at your own risk.

"how did this manage to get the top ranking?"

December 12, 2012  |  By mrambler956

 |  Version: Avast Free Antivirus 7.0.1474

Pros

It did catch some well hidden (though probably inactive) viruses, though those could possibly be false positives.

Cons

Huge, slow, crashed computer.

Summary

I've now tried all three of the major free antivirus programs (Avast, AVG, and Avira), and this was by far the worst. I used Avira for a long time but it got progressively more bulky and was slowing down my computer (plus I was getting sick of the popups) so I decided to switch. I put AVG on one computer and it was fine, and decided to try Avast on the other. Big mistake. It's huge (260Mb compared to 110 for Avira and 90 for AVG), slowed down everything even more than Avira, and then gave me a BSOD crash twice when I tried to install AVG. I finally just removed it before the AVG install and everything is working okay.

"Very nice AV software"

December 12, 2012  |  By aidan0203

 |  Version: Avast Free Antivirus 7.0.1474

Pros

Very fast, does not consume a lot of RAM while on the background (my previous AV almost took about 400 MB of RAM while in the background on my Windows 7 laptop).

Cons

None at all.

Summary

I highly recommend this completely free software to anyone that needs it. Great work Avast! :)
