Choose Your Defender! 10 Anti-Virus Programs Reviewed and Compared
AVG Anti-Virus Free 2012
The king of free AV is back, baby!
The latest version of AVG gets medieval on malware in the same unrelenting manner Duke Nukem hunts down alien scum, only without all the R-rated sound bites (that’d be rad though, wouldn’t it? Hold that thought…). Part of the reason it’s so effective is because of all the weapons it brings to the fight. This is an exciting trend we’re seeing in the free AV field and a marked departure from the days when no-cost security software only provided basic protection.

Too many of AVG's menus include upgrade offers, marring an otherwise awesome (and free) antivirus program.
In this case, AVG hunts down viruses, spyware, Potentially Unwanted Programs (PUPs), rootkits, email‑borne threats, suspicious registry entries, boot sector viruses on removable media, and tracking cookies. AVG proved especially skillful at stopping unknown threats dead in their tracks. This is commonly known as behavior-based scanning, though for whatever reason, AVG chose to attach the moniker “Identity Protection” to this component, a peculiar and confusing choice of terminology that we initially thought was referencing some form of built-in ID theft protection. That isn’t included here, and neither are many of the extras typically stuffed in a complete security package—things like a firewall or parental controls. We did eventually manage to overwhelm AVG’s defenses, so it’s still a good idea to seek a second opinion from a dedicated spyware scanner on occasion. This holds true for all three free AV apps included in this roundup.
AVG’s dashboard is slightly chaotic, and it doesn’t help that it’s littered with upgrade offers. An abundance of tweaking options sits beneath the surface (Tools > Advanced settings), some more fleshed-out than others. And those R-rated sound bites you’re holding on to? You can attach them to a handful of events via a customizable soundboard. Way cool.
If you’re trying to save a few pennies by rolling your own security suite, this is a good place to start.
Avast Free Antivirus 6
Better than basic protection without the price tag
Let’s get one thing straight: Avast’s free antivirus software isn’t going to keep your PC squeaky clean if you’re determined to run reckless on the web and click every download that comes your way. Few programs can. But where Avast shines is in blocking most bad downloads from reaching the desktop in the first place. In our tests, Avast performed at least as well as some of the full-blown security suites, and in some cases did a better job screening websites.
Avast provides real-time protection against an assortment of malware, not just viruses, through eight configurable so-called “shields” you can fine-tune to your specific setup. Heavy file sharers will want to spend some time polishing the P2P Shield, for example, and there are other shields for instant messaging, email, network activity, and more.

Avast's boot-time scan option helps rid your system of deeply rooted malware by attacking infections before they're able to dig their hooks into Windows.
Be careful not to let the sheer number of shields lull you into a false sense of super-security. They weren’t strong enough to prevent every piece of malware from penetrating our test bed, though Avast did an above-average job minimizing the damage from unknown threats. One aspect of Avast we really like is that you can choose to have Potentially Unwanted Programs (PUPs) load in a sandboxed environment. By keeping suspicious programs at arm’s length of the OS, Avast adds another layer of security. Should that not be enough, Avast also includes a boot-time scanner to scrub out stubborn malware before it has a chance to load and defend itself. This was effective in removing some, but not all, of the infections Avast failed to prevent in real-time.
The notion that you always get what you pay for completely ignores the potential value inherent in free security software. More specifically, it disregards the level of protection that programs like Avast provide gratis, at least when combined with safe computing practices.
