    Default Windows Defender impossible to turn on

    Here's a new question that has not been mentioned on any of the forums before. Windows 8 Defender won't turn on.

    A Microsoft Agent could not do it. I can not do it. The next door neighbours dog cannot do it.

    I've even gone against the grain and completely uninstalled / removed Norton 360 and guess what - Windows Defender still won't come one. I uninstalled MalwareBytes / SuperAntiVirus software and nay, Windows Defender will not be turned on.

    Can someone on this happy forum please give me the secret of turning this thing on - the secret is about as secretive as getting the caramilk into the caramilk bars!!!

    You've obviously gone through quite a lot to attempt a re enable, but you do not mention trying to turn on the Servce? In case :: Open Services.msc and scroll down to Windows Defender and ensure it is enabled (Automatic). I have a feeling it will come on and immediately go off again. Before leaving the Services, make sure the Security Centre is also turned on.

    Open the Control panel - Action Centre. Hopefully, you will see a message there "Windows defender is turned off", with a small box to the right "Turn on now". Try this, reboot and see if you are back in business.

    One other thing, MalwareBytes & SuperAntiSpyware plays well with Windows Defender, as they're second line defenses. But Norton 360 is a first line defense, so is Windows Defender on Windows 8. Windows Defender will shut down is another app such as Norton is installed.

    Windows Defender on Windows 8 is an entirely different product than what ships with Windows 7 (& possibly Vista), & is an optional download for XP. From Windows 7 down through XP, Windows Defender is simply a spyware app, a second line of defense. On those, Defender may play well with Norton 360.

    Windows Defender that ships with 8 is a total AV/AM app, if it weren't to shut off when another first line of defense installed, there would be a serious clash going on, plus resource usage would run through the ceiling. Not to mention that protection would suffer, neither would properly work.

    So if you're going to run Norton 360 on Windows 8, forget about Windows Defender. It's one or the other, not both. If you're going to run Defender, then davehc's advise above applies.

    It is possibly unfair to either organisations, to compare a full fledged Security program with a basic Anti virus (Defender) product? I am happy to use Defender, but would only dare rate it against such free offerings as AVG and Avast, etc.

    You may not be happy to hear this but I suffered a similar problem this year with my 2 year old HP Pavilion desk top using windows 7.

    I have been hacked more than once. The best info is that there are some bandit Russians off shore hacking into steal E-mail addresses. Then they use my stolen E-mail to send out a website link to a Canadian Company that sells medication on line. Only problem is that the Canadian Company is a fraud, a scam, it doesn't exist. The photos, testimonials and website are all false creations. The addresses are bogus. People bite and order medicines. Pay with cc. But the product never comes. One has been caught, others are still at large. The woods are full of scammers.

    My Windows firewall, in my Windows 7 wasn't responding. I ran Norton scans and they did detect lots of malware, data miners and so on. But not this apparent embed problem. Things went from bad to worse. So in frustration I hired GuruAid a Connecticut based specialty outfit *( With Indian techs ) and they found the problem. It cost me $169 for a 1 year subscription. They took over my computer remotely and whizzed around for over 45 minutes. Apparently installed some vendor software that cleansed systems.

    I don't know how old your compute is or what type, desk top, laptop, or it's history.

    Now here's the clinker. In Microsoft's last go round they discontinued Defender back in the Vista or Windows 7 era. In Windows 8 they have enhanced it. In my book Windows 8 Step by Step, it says Windows Defender and Firewall are the best FREE protection but if you want better protection then outside vendor software is better. So - you don't actually need Windows Defender and Firewall if you have Norton. My computer said: Your security has been taken over by an outside vendor *( Norton ).

    Now it's the choice: Have the Russian scammers compromised your security or has Norton taken it over? Or both. If it's the Russians you will be getting mysterious E-mails using your name. Your computer will begin acting up, running slower and bogging down, become increasingly non-responsive over time.

    If you're not happy with Norton maybe try Kaspersky software.

    Actually you are probably fighting windmills like Don Quixote in the Spanish novel, persisting in trying to make Windows Defender and Firewall work simultaneously with Norton. It's like having two wife's. * ( Or a wife and a mistress ) !!! Unless you are a Mormon or a Muslim there will probably be trouble in the home !!! With Norton protection doing all of the heavy lifting, Windows D & F are spectators just taking up space and causing headaches.

    I don't run Windows Defender myself, though I do beta test the next version of MSE for MS. As soon as the new version is released to everyone, I get a new beta. I have test OS's for this & other purposes.

    The good news for those who runs MSE is that the next version will include AM as well as AV protection. The bad news is that, it's not much better than the stable version of today, which is why WD/MSE are middle of the road choices (at best). They are there because some users can't afford protection, but doesn't know what to get (the other Free choices). It also means that no one has an excuse not to run some form of AV protection, it's simply downright irresponsible not to run security, not only for the user's protection, but for the sake of others (our neighbors sharing the same lines).

    After careful consideration, I do have to agree with davehc. As much as MS has promoted WD as a next generation AV/AM solution, & against the backlash that I know is coming from Defender's loyal users, neither WD or MSE are on par with commercial AV/IS solutions. That is fact, one can visit any site that ranks security & see. ESET Smart Security 5 is my choice for Windows 7 & below, there's still a glitch in the Firewall that makes it incompatible with 8. Once it's fixed, I'll have it on both of my Windows 8 Pro installs. I even have another boxed version ready to roll once this one expires.

    For the reason that I listed above, I'm running Avast 7 Free until the issue is fixed. On one of my computers, AVG 2013 Free is a bit heavy, I'd prefer to run the same on each. Plus, for many years, I ran Avast with very few issues (from 2002 until 2009, when Windows 7 was released). I also run MBAM Pro as a second line of defense on all of my main installs. Wouldn't dare to run WD/MSE w/o MBAM Pro, have been burned once, but not again.

    Back to the OP's question & how to solve it. Has the info provided by davehc got Windows Defender up & running yet?

    And finally, which choice of security do you want to run? Norton 360 or Windows Defender? If you wish to run a commercial solution, why bother with Defender? Or has there been issues with Norton? If so, there are trials of other products available.

    We can better provide advise if we know what you intend to run. Please let us know, so that we can assist.

    Sorry guys for not getting back earlier. I've got this thread going on what I'll call Metro IE10. I overlooked this because I'm on IE10 Desktop most of the time. I just happened to catch this when I saw it coming up in one of the tiles.

    Anyway, I've used Norton products since '91. But because of the hanging on the Restart, Microsoft advised me to take out Norton. Even after uninstalling the product and using their removal tool, Defender would not work. I couldn't even find it in the Action center.

    So I rumbled off into the Registry and cleaned out remnants of Norton that even their removal tool didn't take out. But Defender still wouldn't come up. So I went back into the Registry and found traits of MalwareBytes, SuperAntiSpyware, AVG, and Avast. The latter I put on after having removed Norton.

    Anyway, after cleaning those out of the Registry, Windows Defender suddenly (and without warning) showed up in the Action center, so I turned it on and it's ok now.

    I'm doing all this to see if the System will hang on Restart. This is still difficult, because even with Norton 360 installed, it would only hang once a week or so and then, I don't restart this system much.

    So it's a wait and see game. If Norton is the cause, I'll leave it off till Norton fixes whatever the snag is. If it hangs again, I'll be slam dunking Norton 360 back onto this system.

    So the saga continues people - stay tuned to a computer near you for further updates. If either of you have suggestions, please advise. Thanks again for your feedback! :-)

    It doesn't really matter. Norton is a fine program, and far more comprehensive than Windows Defender. If it chooses to turn off Defender, sobeit!

    Though Norton did have a bad reputation for a few years (a known resource hog was the main one), that issue has been fixed as of a few versions ago. There's now a resource usage app in there, showing Norton's impact usually to be negligible. I've seen a few recent solutions (BitDefender/Trend Micro for two) to be far more power hungry than Norton ever was.

    The problem is, users tends not to forget the past & give apps second chances, especially security ones. Some, like McAfee, users has reason to be concerned, the crippling of many computers after an update that lasted for many hours, this was just a couple of years ago.

    Norton has to have something going for it, it's one of the top sellers in the US market. The others that I mentioned above, especially McAfee, I'd be concerned about having it on any of my computers. By a long shot, Norton is far better than Windows Defender will ever be.

    One reason for this is that paid security is usually always better than Free. This is true of other apps also, were it not for the fact that Windows Media Center is free (for now as part of the promo), few would buy it. PowerDVD 12 Ultra by CyberLink is on promo for $69, & is far more feature filled.

    Like everything else, one tends to get what they pay for, in most instances.

    Interesting. Worth expounding on more.

    The Russian bad guys could be a culprit. Norton could be too. And more parties too. Not necessarily malevolent's bent on harm but also "friendlies" !

    I have at times received popup's warning that I have some problem and it needs fixing. These seem to come from some vendors trying to sell something. I have also received messages promoting some freeware and some that is cheap. A couple of times I bit and really got burned. Changes were made to my registry. Often I am asked if someone can make changes to my registry and I can either accept or decline. So there are numerous "elements" some friendly, some not friendly that will tamper with the registry and mess things up.

    Surfing around for a long period of time has also loaded me up with things that bogged me down. More than once I have received updates. EVERYONE is always installing updates - really it seems DAILY. Some updates have sent my computer into a tails spin and almost caused crashes. I had to phone tech support to straighten out the messes.

    So a computer is constantly being assailed with changes. When trying to diagnose a particularly confounding problem it probably will pay to keep in mind all of the activity going on frequently when you are off line.
