uh, yeah much like the many, many others who have tried this USELESS advice of typing in 'windows defender' in windows 8 - the ONLY response is a message saying 'windows defender is turned off' and the message box closes - that is the ONLY message - there is no 'settings' option - there is no dialog box - there is ONLY the message 'windows defender is turned off' - as usual - i remain completely underwhelmed by these advertisement updates.

OMG!

Can you people READ?

Microsoft Windows Defender is built-into Windows 8. PERIOD.

What is so complicated about typing in the Search Page, 'defender' ? Disabled or not by other pre-installed crapware so-called antivirus, Windows Defender is still there.

Click on [Settings] (as administrator)

Is this checkmark ON? Duh!
Posted Image

Well you can't turn-on this checkmark (it is grayed out) unless the OTHER ANTI-VIRUS is completely UNINSTALLED, and the system REBOOTED, TWICE!

There are two kinds of people on this Earth. Intelligent ones, and Stupid ones. That is why the average IQ is 100. Which half do you belong into?

Microsoft free support Windows 8 Windows Defender

Rightly, those who bitch and complain, should first call the company where they bought their computers from and ask for support to solve this issue.

But just in case 'the computer dropped from a truck' and found its way into a seedy bar for cash, even Microsoft would support security issues for free!

The only reason for not calling the right source for support is if the unit was 'stolen', since Microsoft and other OEM will ask for your name, contact email, telephone #, address etc... And if the unit was reported stolen (easily tracked by its serial and license number), then tag, you're it!

Buying stolen merchandise or goods is considered criminal activity in most civilized jurisdictions, don't you know?:ph34r:

I'm not saying whether these are genuine units or not BTW. I'm just wondering why people won't call the place where they legally bought their merchandise for technical support? Best Buy? Wal-Mart? Or Samsung or HP? WTF (Where To Find)?;) What have you got to hide?

Microsoft free technical support regarding updates and security issues

For those of average intellect with an IQ of > 100, please go back to the article, and also the top of the thread and please re-read the step-by-step instructions carefully, if you can understand what you are reading.

Others, get lost! You are just wasting our time and bandwidth, trolling or worse...

Have you uninstalled Norton? Well if Norton is turned off, that means it still is installed? Have you completely uninstalled Norton? And then rebooted TWICE?

You might try this first? That is the most difficult part after all.

What's the point of reading I suppose?

Windows Defender works great for me. In fact, it's so flawless, I almost forget it's there. I haven't had to mess with it once. The only issue is that Microsoft Security Essentials (which Defender is based on) failed the latest AV-test mostly because of it's inability to catch any zero-day malware. http://download.cnet...latest-av-test/ Though Defender is suppose to be a bit better than MSE, until they start showing some improvement there, I wouldn't be able to sleep easy.

You really should read the articles you site. It says that MSE stopped two-thirds of the zero-day malware. Which is the first time I have ever heard of MSE not being one the best AV software packages out there. Makes me question the tests.

Just got an Asus Taichi with Windows 8 and, of course, a McAfee trial pre-enabled. I tried the process outlined above but when I clicked on the Windows Defender icon, a small window popped up saying Windows Defender has been inactivated. Period. No options whatsoever. So, I uninstalled McAfee completely and tried again. Same result. How can I get at Windows Defender?

Well, unless your system is already infected with something nasty, perhaps you could try these additional steps?

Unfortunately, malware has a tendency to go and screw up the system so the built-in protection becomes unusable.

Regardless, on a proper, non-adulterated system, Windows Defender is built-in, and can work provided there are no other Anti-Virus running.

Please go to the computer management screen, and click on Services, then look for Windows Defender Service:
Posted Image

Make sure the service isn't disabled. If it is, simply force it to start:
Posted Image

Then also change the startup parameter to automatic, and restart the computer.
Posted Image

Assuming all other anti-virus are completely purged from your Windows 8 system, then after the restart, you should be able to access Windows Defender as per the methods described earlier.

Then please come back and tell us if this works?

Thank you and Good Luck!

In case your system is already compromised by these 'trial' anti-virus expiring, then leaving your PC unprotected, and subsequently are having issues starting any anti-virus package whether from Microsoft or other brands, here is some useful info that might help.

Microsoft said:



There are many benefits from booting a clean OS, before attempting removal of any active virus fighting for its life! If booted clean, then the virus is dormant, and not active. This facilitates the detection and eradication of malware with extreme prejudice and efficiency.

Of course Microsoft Defender, online or offline versions are completely free. Think of it as a goodwill gesture from Microsoft.

The astute won't create the bootable offline version, from the same infected or suspected PC, of course? I mean, how difficult is it to get your hands on a PC nowadays?

When I follow your advice to open Windows defender to activate all I get is a warning that defender has been turned off on my computer, and to go to the app now monitoring my computer. How do I change this? The device has Norton Trial bundled on it and it is about to expire. I have windows 8.

First, head to the modern-style Start screen and type "Windows Defender" to have Windows search for the program, then click on the Windows Defender icon when it appears in the results. A Windows Defender window will appear on the classic desktop.
"No it doesn't!" Only a box stating defender has been turned off and to go to the current app monitoring the computer.

  • You cannot enable or 'activate' (the article title is a misnomer) Windows 8 Defender if there are other third-party security software running installed.
  • Since your device got the Norton Trial bundled as 'bloat-crap-ware' by the OEM factory installed, then you cannot enable Windows Defender-->
  • Until you completely uninstall the offending and incompatible antivirus, and reboot TWICE.

Then enabling Windows Defender becomes child's play.

For the benefits of those who do not go back to and read the beginning of a thread (where solutions are usually found on the first page on post #19), here it is:

I have a new computer with Windows 8 that came loaded with a heap of Norton 'stuff'. I cannot turn on Windows Defender - Control Panel - Security - offers no mention of it (that I can see) and Search - Apps - Windows Defender - only says 'Windows Defender is turned off' and offers no way to access it to 'turn it on'.
Any suggestions?


Unfortunately, Norton is the virus. Or is malware at the very least, since they purposely make it so hard to uninstall. But it is possible.

  • First thing to do is to Google uninstall norton:
    Posted Image
  • REBOOT!
  • Verify Norton is gone, with all the accompanying crapware. It usually leaves some Symantec/Norton stuff like auto-updaters etc... If not entirely clean from this bloatware, go back to step 1 and 2, until finally disinfected clean.
  • REBOOT again! Why not it only takes six to twelve seconds or so on a clean Windows 8 system. Even a low-end one.
  • Go into Start Menu (lower left corner) and type Windows Defender (as administrator meaning login with your admin account, not the regular non-admin one)
  • Click onto the filtered search results (Windows Defender application)
  • Navigate to {settings}
  • Checkmark Turn on real-time protection (recommended) and save changes then you're done!

The most difficult part will be to uninstall the bloat-crap-malware from Norton.

Good luck, and Happy New Year everybody!

PS: a properly configured Windows 8 system will cold boot in six to twelve seconds, from initial power-on of the system. Anything above that mark is caused by bloat-crap-ware. Unfortunately.

I'll show you mine, then you show me yours...

  • I type defender in the start screen:

  • After I click on the Windows Defender found in the context sensitive search I get this on the Full Desktop mode:

  • Perhaps you should follow exactly all the instructions, step-by-step in the prior post #57?

Welcome Carlo, please read the posts on this page (for brevity) and follow the steps-by-steps, precisely. Do not skip any steps! Or it won't work for you.

Now if you had McAfee instead of Norton, then simply uninstall McAfee first!

Good luck!

My computer came with McAfee trial installed. Any ideas? or if I uninstall McAfee, will that solve my problem? That will probably solve the problem. It is considered bad practice to have two AVs running at the same time (they tend to fight with each other).


I have this same problem. I uninstalled McAfee trial and restarted the laptop, but I till get the same message. I don't understand what I'm supposed to do now to activate Windows Defender! I am left with NO virus protection. Please help.
