    "Most likely a fail"

    May 19, 2013  |   By VulpeX

    Version: Microsoft Windows Defender 1.1.1593

    Pros

    + promises additional protection
    + included in the recent Windows systems

    Cons

    - full scans take literally hours
    - many here report they never get any results (what could be a good thing but most likely isn't ;))

    Summary

    As many other reviews indicate, this little security tool is not really doing you a favour. It may be an additional protection against malware from installed programs. If you install a lot of apps regularly the features make sense. However it is not a replacement for a virus scanner!

    Updated on May 19, 2013

    After some additional research, I need to add a bit of information.

    Alas, the MS team has decided to give the Windows Defender a full virus protection - but only under Windows 8. This may lead to further confusion and people may believe they got a virus protection while they have not.

    "Waste of resources"

    April 7, 2013  |   By JoelCairo

    Version: Microsoft Windows Defender 1.1.1593

    Pros

    None that I can see

    Cons

    Uses tons of resources and never finds and spyware.

    Summary

    As a systems administrator I have come across windows defender many times and I have never seen it do anything useful. It's like having a button that uses 15% of your system resources, pointless.

    I don't use an anti-virus or anti-spyware program, a firewall is all I need. Those 2 programs eat resources and slow down your system ten fold. Ignore, disable and mock.

    "Seems to work fine."

    October 3, 2012  |   By BobV4244

    Version: Microsoft Windows Defender 1.1.1593

    Pros

    I had it installed for 2 years then decided to install Kasperky. After a 12 hour scan Kaspersky found no threats so Defender must have been working perfectly. I may have wasted money on it.
    Please comment.

    Cons

    I wish it had been on xp all those years.

    "It does nothing."

    September 13, 2012  |   By Mar_Enz

    Version: Microsoft Windows Defender 1.1.1593

    Pros

    It's free and from Microsoft.
    On second thought, I'm not sure this is a pro.

    Cons

    Windows Defender is just like the proverbial goggles in the Simpsons episode: it does nothing!
    I work servicing computers. I have seen DOZENS of PC's infected with all kind of malware, that have Windows Defender installed and running. Neither the alleged real-time protection, nor the scan detect any malware. And the only time I saw it detect something, it turned out to be a clear and cut false positive.

    Summary

    Don't waste your Pc resources with this. Get a real Antivirus and a decent Antimalware protection. There are many applications that are effective, and still free.

    "Resource Hog and useless"

    September 6, 2012  |   By Vanillaman

    Version: Microsoft Windows Defender 1.1.1593

    Pros

    None that I have found over a long period of use

    Cons

    Devours resources. Has no uninstaller. Zero results

    Summary

    Totally pointless waste of time and resources

    "Works as Described"

    May 23, 2012  |   By SixT7VDub

    Version: Microsoft Windows Defender 1.1.1593

    Pros

    Works just as it's supposed to.

    Cons

    None so far.

    Summary

    I'm not sure what everyone is complaining about. I use my computer pretty much all day everyday and have never come across as many Trojans as everyone is talking about.

    Cons

    Summary

    Pros

    I can't find anything as I can't tell if it actually doing anything.

    Cons

    Never found anything in all the time its been installed. It came pre-installed with my computer. Keeps telling me to set a scheduled when I have done it many times.
