Microsoft Security Essentials fails to gain certification from anti-virus testing company


AV-TEST Institute is an organization that runs anti-virus/anti-malware tests. During AV-TEST Institute’s latest Nov/Dec 2012 anti-malware testing, 3 out 25 anti-virus software failed to gain certification. One of those 3 is Microsoft’s popular Security Essentials. (The other two are AhnLab V3 Internet Security and PC Tools Internet Security 2012.)

According to AV-TEST Institute, Microsoft Security Essentials failed to satisfactorily protect against 0-day malware attacks, scoring only 71 percent detection rate. The reason why I say only is because the industry average sits at 92 percent. Microsoft is, of course, none too pleased with the outcome and conducted a “rigorous review of the results” plus protested that only 0.0033 percent of Security Essentials users were affected by the malware that went undetected by their software in the tests.

It appears that the company is not just challenging these particular results, but the usefulness of testing against anti-virus in general. They claim that it is “difficult for independent anti-malware testing organizations to devise tests that are consistent with the real-world conditions.”

You have to wonder, would their statements sound like this if Security Essentials simply passed the test with flying colors? We’ll never know. Despite all that, Microsoft says they are “committed to reducing” the 0.0033 percent of users affected to zero.

    Been using Avast! free for years, but due to the good things I’ve read about BitDefender I decided to try it on my new Win8 system. So far I’m impressed… fast, light on resources, and a simple interface.

    Hello, all.
    Well, DAGNAB-IT!
    AND I just completed a 2-days&1-nite complete system scan w/ “MSE”!
    Now I gotta’ try some other programs.
    Which, actually, I intended to do, anyway.
    Last couple ‘o days, I’ve had 2 different browsers and 2-3 other programs just up & crash.
    So, that’s a ‘sign’ that its time to scan the daylights outta’ my system.
    I just dwnldd a whole slew of softs, to try out.
    Here’s the list; see if any are potentially as ‘useful’ as “MSE”.
    a-squared Free.exe
    Malwarebytes Anti-Malware 1.70.01100.exe
    Ad-Aware Antivirus Free.exe
    Spyware Terminator.exe
    Spybot Search & Destroy 2.0.exe
    I’ve used almost all of these, at some point, but I haven’t keep up w/ them, so I’ll appreciate the input.
    Have a GREAT day, neighbors!

    @Enrique: Absolutely–and whatever will get tech. companies to improve their products is great with me . . . .

    @Mike: It’s bad press, so that’s probably why they’re concerned :)

    MSFT is about hype and sales; quality and performance are afterthoughts, if considered at all. Their destiny is obvious… Too big to fail???

    Come on all you programmers, where’s your winOS alternative??

    I had MSE on three computers in my home. The only times that it ever found anything on my drives was after I began to run a manual scan with another program like Malwarebytes Anti Malware. Partway into the scan, MWB would find something, and then out of nowhere MSE would pop-up with a quarantine message. Anyway, I had to get rid of MSE. I now use Avast (free).

    Personally, I am impressed that Microsoft is concerned.
