windows defender not working in my windows 8

Dear Sir,


My windows defender in windows 8 is not working and not turning on.I read through several links and answers in this community and other communities but nothing worked.I refreshed my Dell N5521 laptop but still problem remains same. When I go to control panel and try to click the defender icon, it says, ' defender is turned off and its not monitoring my pc'. and also asks me to check the status of other apps in action center but I don't see any change there.all are on and ok, except network access protection turned off and not able to turn it on. also my windows is not updating and says error and failed to install. I am worried with this windows 8. Kindly help me out.I am very basic to windows 8,so please guide me to make my laptop usable without any issues.Thank you. 

no, don't install anything else as long as you are running Windows Defender.They will conflict with each other and adversely affect your computer. Microsoft has greatly improved  their security with the improvements to Windows Defender, SmartScreen Filter, and other security in IE10. There are even more improvements in IE11 to be released with Windows 8.1 later this year. Hope this helps and if you need any further assistance post and we will be glad to help you.
