    October 24, 2014  |   By acollardeau

    Version: Microsoft Security Essentials 4.3.216

    Pros

    CANNOT BELIEVE IT HAS REMAINED FREE FOR SO LONG! MICROSOFT LACK OF GREED AMAZES ME IN THAT INSTANCE, THANK YOU & PLEASE, KEEP IT FOC AND KEEP UP THE GOOD WORK !!!
    WORKS VERY WELL FOR ME SO FAR (I REPLACED NORTON 360 WITH IT)

    Cons

    CANT FIND A 'REAL' FLAW, COULD PERHAPS BE GEARED TO TURN OFF THE MACHINE?

    Summary

    GO FOR IT REST OF THE WORLD !

    "It worked for a while but now?"

    September 1, 2014  |   By juditte

    Version: Microsoft Security Essentials 4.3.216

    Pros

    Runs very quietly - no stress on system

    Cons

    No longer seems to provide the best security. I got hit by some small stuff it did not identify. Fortunately no serious trojans or the like. So I think it is no longer doing the job it did before.

    Summary

    A reasonable search showed that a lot of people are finding that MSE is no longer keeping up with the need. So the next question is go with what? The c*&p I got I used Malwaarebytes free to get rid of. Now of course it wants me to buy it - but is that the right choice? sigh.

    "Worse than Worthless - It's a False Sense of Security"

    August 27, 2014  |   By j-a-lind

    Version: Microsoft Security Essentials 4.3.216

    Pros

    None -- ZERO!

    Cons

    Consistently ranked as the WORST AV software in effectiveness since 2012.
    In Feb 2014 tests by AV-Test, an independent AV testing and evaluation organization:
    Failed to detect 29% of zero-day attacks!!
    Failed to detect 20% of known widespread and prevalent malware!!

    Summary

    M$ Security Essentials may have had a strong beginning in 2009, but M$ has been grossly negligent in maintaining it, particularly in updating its ability to detect, prevent and clean up viruses, Trojans and worms. Its performance sank so low two years ago in 2012 that AV-Test, an independent AV testing and evaluation organization, REVOKED and REMOVED its certification of MSE. It has yet to be restored in the two years since then, in spite of repeated testing by AV-Test.

    MSE is the rock bottom worst AV software, paid or free, for WinXP, Vista or Win7. Note that MSE cannot be used in Win8. It was replaced by Windows Defender in Win8 (and Windows Defender only works in Window 8). Like MSE, it also ranks rock bottom among AV software. It's as bad if not worse than MSE.

    There are substantially more effective FREE AV solutions. Among them are Avast!, Avira, and AVG. All three consistently rank in the upper tier among free and paid AV software for effectiveness.

    "better than nothing."

    August 2, 2014  |   By ChoiceVoice

    Version: Microsoft Security Essentials 4.3.216

    Pros

    -no false positives
    -fairly light on system
    -non intrusive
    -easy interface
    -does not identify competitors as malware
    -no bsod

    Cons

    -very poor detections/protection as testified by all independent testing laboratories (it is now only used as a bottom baseline to order all the better detectors/protectors).
    -not supported on windows xp (figure that out, all the other private antivirus companies support xp, but microsoft doesn't support its own operating system.
    -not for other os (mac or linux)

    Summary

    there is far better freeware out there.

    "useless!!!"

    July 26, 2014  |   By lizb1972

    Version: Microsoft Security Essentials 4.3.216

    Pros

    it is free, that's all i can say about it.

    Cons

    i'm not a novice, or a reckless internet user, this didn't protect from viruses, trojans, worms, etc. sorry MS fanboys/girls, this just does not cut it. there are better free antivirus out there, like avira, avast, malwarebytes, etc.

    Summary

    i'm back to paying for norton 360, my pc is worth paying for real protection.

    "Best when customized"

    July 6, 2014  |   By tomysshadow

    Version: Microsoft Security Essentials 4.3.216

    Pros

    Really good and thorough scanning, has actually protected me against various viruses, very few false positives, is included in Windows 8 as Windows Defender, realtime protection is not slow, does not return false positives, and is almost instant

    Cons

    Default settings are poor. Enable archive and disk drive searching. Lower CPU Usage if necessary.

    Summary

    Good after you tweak it correctly.

    "False Sense of Security"

    April 18, 2014  |   By Krupotkin

    Version: Microsoft Security Essentials 4.3.216

    Pros

    None, really.

    Cons

    Microsoft Security Essentials offers only a false sense of security. It has been flunking independent tests for the past year. Rather than fix the problems, Microsoft has made excuses. First, it was: "These tests don't measure protection against realistic threats." Then, it was: "People don't seem to understand. Microsoft only provides baseline protection." Bottom line, in a recent test, this service finished dead last of those tested, missing 41% of threats. I just ran AVG Free and found that there were two Trojan Horses that MSE scans have been missing for God knows how long.

    Summary

    Get good third-party protection if you value your computer.

    "PAYING FOR ANTIVIRUS SOFTWARE IS LIKE BURNING MONEY"

    April 5, 2014  |   By eon17

    Version: Microsoft Security Essentials 4.3.216

    Pros

    It provides a decent security blanket over human error. The only software that tops this is malwarebytes. This is nice however because its FREE and does not practice in the arts of fear mongering like ALL of the paid for antivirus.

    Cons

    None. Honestly. It does what anti male-ware software is supposed to do. It provides a real time security blanket to assist you while your educating your self on how to not use the internet like a complete idiot. There is not one, and when i say one I literately mean there is not a single antivirus that you can pay for that will run better.

    Summary

    HEED MY ADVISE. THE PEOPLE WHO COMPLAIN ABOUT THIS SOFTWARE TITLE ARE THE SAME IDIOTS WHO FEEL ENTITLED TO ACT COMPLETELY RECKLESS ON THE INTERNET BECAUSE THEY JUST INSTALLED AN "ANTI-VIRUS" SOFTWARE TITLE. THERE IS NO SUCH THING AS "ANTI-VIRUS". IT IS 100% FEAR MONGERING MARKETING GENIUS BY THOSE WHO RELEASE THE PAID FOR TITLES. TO GIVE EVIDENCE LOOK UP THE REVIEWS ON ANY OF THE PAID FOR TITLES. THEY WILL BE EVEN WORSE THAN SOME OF THESE REVIEWS FOR A FREE... COMPLETELY FREE... WORKING... EFFECTIVE TITLE... WHEN PEOPLE BUY SOMETHING THAT IS MARKETED AS AN "ELECTRONIC DEFENSE BARRIER" THEY FEEL LIKE THEY ARE FREE TO ACT HOWEVER BIG OF A FOOL AS THEY WANT. THEN THEY REALIZE THAT THE SOFTWARE THEY PAID FOR IS COMPLETE GARBAGE. SO THEY GO BUY ANOTHER TITLE. RINSE AND REPEAT. FUN FACT FOR ANYONE WHO CARES. THE ONLY ANTIVIRUS... TRUE ANTIVIRUS.... IS EDUCATING YOURSELF BEYOND THE BASICS. IF THE PROSPECT OF NOT RUNNING ANTIVIRUS PROTECTION TO GUARD YOU ON THE JOURNEY TO YOU FAVORITE FACEBOOK GAME SENDS PEE RUNNING DOWN YOUR LEG YOU ARE DOING NOTHING BUT MAKING YOURSELF STUPID. YOUR STAYING NAIVE. ALL OF WHICH IS IN COMPLETE VAIN. LIKE I SAID, THERE IS NO SUCH THING AS ANTI-VIRUS. IF THERE WAS, THERE WOULD NOT BE 20 TITLES TO CHOOSE FROM AT YOUR LOCAL OVERPRICED RETAIL TECH BIG BOX STORE. DO YOUR SELF A FAVOR AND WAKE THE HELL UP. EDUCATE YOURSELF. EVOLVE. THIS COMPUTER STUFF.. ITS NOTHING TO BE SCARED OF. SHOW SOME DIGNITY. LEARN FROM YOUR TRIALS AND ERRORS. STOP BEING SUCH CONSUMERS IN A MARKET YOUR NO NOTHING ABOUT. YOUR GOING TO GET BURNED AND YOU WONT EVEN KNOW ITS HAPPENING.
