How secure is your PC?

avast! Free Antivirus


The install was relatively quick, with the option to install Google Chrome and setting it as the default web browser. I guess I can’t complaint much about this since it is a free antivirus after all. As soon as the install finished, avast! quickly updated itself in the background just as the main interface was loading up.


Overall avast! looks very simple and intuitive, with the main screen showing the currently activated features and further access to the features on the left tabs panel. On idle, avast! uses up around 8mb of system memory, while running full scan takes roughly 18mb of memory! The program version tested was 5.0.677 and virus definition version was 101226-0.


Since this is a free antivirus, it doesn’t come with the built-in firewall, so Windows Firewall needs to be enables, or any other third party firewall. The second issue, which again is not really a big deal considering this is a free AV, is that you have to install Flash Player 10.1 to check out the statistics graphs.


The first complete system scan took a time of 6:56 with 166276 files canned, while the second complete scan took 3:38 to scan 166255 files. During scan, avast! used 1 core and 2 threads using roughly 20% of CPU power continuously. That’s pretty impressive scan times considering how low the load on the system is.

As for the malicious website test, I looked at a Trojan file where avast! outright blocked the page from even loading.

From auditing to editing, I now test and analyze the latest gadgets and games instead of the latest financial statements. Both jobs are equally intense and rewarding. When I'm not burning up hardware in the name of science, you'll find me nuking in DOTA 2 or engineering in TF2.

    Wondering why you didn’t test MSE

    i have switched from kaspersky KIS to it about a year ago when my license expired and haven’t looked back.

    I agree. How can you not include the best av out there in your test? MSE.

  • Smeagol107

    personally I like Vipre-very fast and non intrusive

    I’m sorry but this article tests the AVs too briefly and superficially to make assumptions.
    It’s known that Avira Free has a higher virus detection rates than most (if not all) the freebies, and that’s pretty important when scanning for malware.
    I’ve already cleaned countless machines that had Avast! installed. Avira or MSE detected what Avast! hadn’t.

      Thanks for your insightful comment Tommy- is there a website or a file that we can download from somewhere that we can use for future testing of anti-virus applications?

        Try on eicar, although is pretty outdated. You should try with an infected machine, clone its HD and test with various AVs.

        Also, check this site:

    I have to agree with most of the post right now. IMHO Avira is a far better AV than avast, I’ve been using it for a while now and I’ve been protected by it countless times.

  • Wkarls

    I use Vipre period

  • Taimoor Hafeez

    Not using MSE was a result of a series of some seriously unfortunate events, it’ll be there next time for sure.

    I use a regular at ESET. Their software is very easy. While in office we use Norton, I know a website that offers up to 60% off for security software. Over the past two years I buy from them.
