The setup routine reported a crash on one system, but it recovered and managed to complete the installation without further incident. The product offers several different scan types; for testing I chose the full system scan.

I also turned on the option to scan for PUPs potentially unwanted programs , which was disabled by default. In every case, avast! When the boot scan came first, I ran a full scan afterward just to be sure. On my standard clean test system the full scan alone took 21 minutes, well below the current average of 30 minutes. However, running a boot scan added over 20 minutes more.

If you set up a boot scan and walk away, it can take a lot longer than 20 minutes. As soon as the scanner finds a threat it halts, awaiting your choice of action. You can delete, quarantine, repair, or ignore either the threat or all found threats. If you don't choose an option that applies to all threats the scanner will stop and wait for your response for every threat it finds.

I choose "move all to chest" quarantine in every case. Even after that, if the scan finds a threat locate in the Windows folder you'll have respond to another confirmation prompt. Boot-time scanning is smart, as it lets the antivirus do its work with no possibility of a rootkit or other devious threat interfering. You'll probably want to configure the boot scan settings to automatically move all found threats to the chest, thereby avoiding any possible hangup.

Effective Malware Cleanup Avast! With 6. Some of the malware samples are rootkits, threats that interfere with Windows to hide their traces. Like many of its competitors, avast! It did leave behind some executable rootkit components, but its rootkit-specific score of 7.

I also break out a separate score for removal of scareware, also known as fake antivirus. Less Effective Malware Blocking In my malware blocking test avast! Webroot aced this test with a perfect 10; Comodo Antivirus free, 3 stars came in second with 9.

Looking specifically at blocking rootkit threats, avast! It detected all the rootkits, but one of them managed to plant executable files on the system and another actually launched its rootkit technology. On the plus side, a full scan did remove the offending rootkit.

Webroot, Comodo, and Norton blocked rootkits perfectly, thereby achieving the maximum score of 10 points for rootkit blocking. As for blocking installation of scareware, avast! Eight "shield" modules provide avast! The web shield was particularly effective at preventing access to known malware-hosting sites.

When I tried to re-download my malware collection it blocked most of the still-extant URLs and killed off one threat immediately upon download. With 89 percent of downloads blocked avast! In theory, the web shield should also block access to phishing sites, but I didn't see that at all. I ran my usual antiphishing test long enough to accumulate 25 verified and very new fraudulent sites. Norton blocked 88 percent; avast! Given that my antiphishing test is quite time-intensive, I didn't continue.

Good Lab Results Avast! In on-demand testing by AV-Comparatives. AV-Comparatives also runs a whole-product dynamic test; avast! To understand the difference between good lab results and great ones, consider Bitdefender. It, too, passed nine of the last ten VB tests. Automatic Sandboxing The full avast! A program running in the sandbox can't make permanent changes to the system, which means you can run suspect programs without worry.

With avast! Of course, other program components will handle known malware. Autosandbox only kicks in when an unknown program seems suspicious. New in this edition, you can fine-tune the way avast! For example, if you're a developer or someone who uses many uncommon programs, you might set it so it doesn't sandbox a file merely due to low prevalence. In my testing, the only program that triggered this feature was an analysis tool that I wrote myself.

Naturally such a program has very low prevalence—nobody has a copy outside my office.
