Windows Defender won't start no matter what I try--a virus?

After I upgraded my main computer to windows 8.1 and finding that I had a conflict with Kaspersky and a few things I needed I decided to use Windows Defender on all my Win 8.1 computers as the subscriptions came up. 

 

So... now I was uninstalling Kaspersky and every other anti-virus I could find on a laptop so I could turn on Windows Defender. But, every time I tried to turn it on in the control panel, it would just take me to a windows explorer window.

 

If I try other methods to activate it I'm taken to a screen that gives this message:

"This app has been turned off and isn't monitoring your computer....

If you're using another app to check for malicious or unwanted software, use Action Center to check that app's status."

 

I found an instruction on a windows forum to turn it on from the command prompt using this command:

 

sc start WinDefend Enable

 

The result was this message:

"Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source."

 

Ultimately, I was going to come here anyway after I finished this task because this computer has been running terribly slow and I already suspected infections that weren't detected by running just the standard Kaspersky and Malwarebytes.

 

Any help is greatly appreciated!

Please download Farbar Service Scanner (FSS) and run it on the computer with the issue.

  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center/Action Center
    • Windows Update
    • Windows Defender
    • Other Services
  • Press "Scan".
  • It will create a log (FSS.txt) in the same directory the tool is run.
  • Please copy and paste the log to your reply.

Do you use Kaspersky as your AV program?

I was previously. But, the subscription expired and I'd decided to give Windows Defender a try since it's Windows 8.1 and I'd had some trouble with Kaspersky & 8.1 on my other computer.

 

I thought I uninstalled it correctly. Maybe not?

It looks like Kaspersky didn't remove one registry setting which keeps Windows Defender off.

 

Following steps involve registry editing. Please create new restore point before proceeding!!!
How to: http://www.smartestcomputing.us.com/topic/63983-how-to-create-new-restore-point-all-windows/
 

Press Windows logo key aa922834-ed43-40f1-8830-d5507badb56c_91. and start typing the following:

regedit

Press Enter.

 

Registry Editor will open.

Navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender

In right pane you'll see following line:

DisableAntiSpyware

Right click on  it, click "Modify".

Change the value from "1" to "0".

Click OK.

 

Exit registry editor.

 

Restart computer.

 

Press Windows logo key aa922834-ed43-40f1-8830-d5507badb56c_91. and start typing the following:

services.msc

Press Enter.

 

Services window will open.

Scroll down to Windows Defender Service.

Right click on it, click "Properties" and under "Startup type" select "Automatic" from drop down menu.

 

Restart computer and see how it goes.

I tried to create a restore point but got this error message:

 

"The restore point could not be created for the following reason:

 

The writer experienced a transient error. If the backup process is retried, the error may not reoccur. (0x800423F3)

 

Please try again"

 

So, I tried again... same result. I rebooted & retried... same result.

 

Could this be a disk drive problem?

 

Thank you.

I doubt.

In your case we're not making any serious registry change so skip creating restore point and go on with the rest.

OK. Tried that and got a message window titled:  "Error Editing Value"

 

"Cannot edit DisableAntiSpyware: Error writing the value's new contents."

 

Now... this looks like something's pretty fishy, eh?

Yes.

Before we run some more tools try the above again from safe mode.

Running Security Check and here's what happened:

 

' ' Preparing ' '   showed on screen then a small window popped up saying:

 

Autolt Error

 

Line-1:

 

Error:Variable must be of type "Object".

 

I just left that on that screen in case there's something more you want from there.
