I get an error code 0x800106b5 while trying to start Windows Defender.

Original title : windows error: 0x800106b5 won't let me start windows defender, help and support, connect to the internet, etcetc

 

Okay, I'm on Windows Vista & I keep receiving the same windows error: 0x800106b5. I need help with this issue as I can't do anything!

I've searched on the internet, but nothing.

Everytime I try to start up Windows Defender it says "Windows Defender is turned off. Windows Defender won't provide protection against harmful or potentially unwanted software and it won't send you alerts because it is off. To help protect your computer against harmful or potentially unwanted software,Turn on and open Windows Defender."

So I click the link...takes forever to load and it says "Your computer is running normally." Well, it's not because when I try to connect to the internet when I scroll down to network it says "Connection Status: Unknown. The dependency service or group failed to start" When I right click and press "Connect to a network" it says "Windows cannot find any networks" and behind the Network, Windows Defender stops and says "Service has stopped. A problem cause this program's service to stop. To start the service, restart your computer or search Help and Support" It won't let go on Help and Support "Help and Support was not able to start. For more information contact your system administrator or visit http://windowshelp.microsoft.com."

I've searched on the internet and found this websitehttp://support.microsoft.com/kb/555962 but when I type in the commands it comes back with "WMI repository is consistent"

I don't know what to do! I've tried almost everything and running out of ideas. :(

Try the following: http://support.microsoft.com/kb/931849/en-us which addreesses Defender and this error code.

I hope this helps.  If not, what other security software do you have installed on your system (names and versions)?

Good luck!

Nope, i've tried everything, nothing seems to be working. When I go into services everything says Automatic and Started, Including Windows Firewall. It says it's automatic but the service status has stopped. When I press Start a pop-up comes up saying "Windows could not start the Windows Firewall on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 87."

When I go onto Windows Firewall with Advanced Security it says "Windows Firewall with Advanced Secuirty snap-in failed to load. Restart the Windows Firewall service on the computer that you are managing. Error code: 0x6D9."

Also, when I restart my computer, when I log onto my user it says Welcome for a long time (It didn't used to take so long) then it changes to a black screen for an extra 5 minutes and finally brings up my wallpaper and everything starts. But, something pops up everytime in the task bar when I turn on my laptop which I've never seen before. "Failed to connect to a windows service. Windows could not connect to the System Event Notification Service service. This problem prevents limited users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond." But it doesn't give me an error code to try and fix.

When I go into Windows Security Center, under Security essentials the four options which include Firewall, Automatic Updating, Malware Protection and Other security settings. Everything is set as OK apart from Automatic Updating. When I try to change the settings, I click "Change Settings..." and it pops up "Install updates automatically (recommended)" so I click onto it but nothing changes.

I do not have any other software any more as I've uninstalled all the limited time ones and the ones which aren't free. But I believe everything started happening after uninstalling these programs. I used to have PC Tools: Spyware Doctor, Malwarebytes: Anti-Malware: Malwarebytes, Fake Anti-Virus 1.64, McAfee and possibly more. (I recently removed a malicious virus/fake anti-virus software.)

 

Sorry about the long paragraphs, it's a  very stressful matter and I have a lot of things wrong with my computer and it's taking me around in circles!
