Windows 8 defender won't turn on

I have only just realised that Windows 8 has a perfectly good antivirus and anti-malware features of its own. Not realising this before I have installed and uninstalled both AVG and Bit Defender. I tried to turn on Windows 8 defender but it refuses. It does not say that I am or am not protected against viruses. How can I tell whether I am protected and, if I am not, how do I turn on Windows 8 Defender?

[perfectly good antivirus and anti-malware features ]

That of course is open to opinion. It is certainly not my cup of tea regarding security programs.

You have uninstalled AVG and Bit Defender, You should only be running one anti-virus program and not two.

You will have to go to the AVG and Bit Defender security sites and download the proper removal tool from there for both of them and then run it.

Then if you want Windows defender go to Control panel and click on it from there to open it.

If it still does not open go to Services and scroll down to W/Defender and make sure it is set to automatic. See if that helps.

Thanks Jock1e for your advice. In fact I had AVG and Bit Defender sequentially and uninstalled them with Revo uninstaller which is quite thorough. I did though follow your advice and got uninstallers from their websites and ran them with what appeared to be little effect. Going to services turned it on for about 1 second and then off as usual. What seems to be going on is that once you have used an external antivirus (Macafee was on the Windows 8 DVD) it won't go back to Defender.

Any thoughts on a registry tweak?

Have a look in Action Centre and see what it says under security. Here's a handy link on security software uninstall utilites, click here.

I always run these utilities in safe mode. Revo isn't good enough for such cleaning and will help to corrupt the repository folder.

It's a registry corruption due to removing security software in an improper way I think. I deleted the repository sub folders and rebooted. I now have the flag showing a cross in the notification area even though I have full security, Defender in Win 8 is part of the OS and quite potent I think, backed up with another antispyware program. I even deleted the repository folder, rebooted, and still flagged as problems. So the old way of deleting the sub-folders (win 7) doesn't work with 8.

It's a registry problem, no doubt. Going back to a an image. Sorry I couldn't help further.

Now up and running and Defender as default and Malwarebytes pro. Flag running as no problems.

To be honest I've run Avast, then AVG, then back to Defender in Win 8.

If you're not a porno freak or serial killer then Defender is quite good enough if you follow safe searching.

Link I found for free version of McAfee SiteAdvisor, needs careful consideration as you will need to untick unwanted toolbars I think but worth while in my most humble opinion.

Back here and the link is C|NET, be aware to untick whatever toolbars are offered.

Thank you guys for your interest. I did try a registry and generally magic cleaner but the Windows Defender service would still not stay started. I think I am going to install a third party security program.

pangloss , installing some free security such as AVG will be OK. Add to that Spywareblaster (by Javacool only) free, Malwarebute and SAS. Safe browsing and you'll be OK.

Have you tried going to Action Center via the control panel and switching it on there then selecting update quickly? From here.
