Windows Defender 0x800106ba error

For me it's both too. Not only full scan.

I am having the same problem: hope Microsoft will fix this soon

Also having the same issue, needing help Microsoft, not happy

Same error, but luckily i found this nice forum! Finaly no more digging through xp/vista threads

Yeah, same problem here too.

I'm not sure whether it's related, or just coincidence, but I noticed the last two days my DNS server has been resolving Windows Update queries to Akamai Germany (Akamai Technologies Duesseldorf / Deutsche Telekom AG), as opposed to the usual Akamai IP addresses. But, like I said could just be coincidence.

Thank you for starting this thread. I am having the same issue. I am running version: 1.145.1483.0. I really hope a fix is created soon!!

 

[Halleluja]

So new update and the same error again
This is my version:

Glad I found you all. A misery shared is a misery halved! I thought I had a virus but it seems that it's only an update glitch. Whew! Many thanks.

I'm going to install avast for a while untill this problem is fixed. I've received a new update today, but this didn't solve the problem. I still get the same error

Hi Guys
I have the same problem with the virus definition 1.145.1483.0 but this morning with the latest virus definition 1.145.1490.0 it's all ok!!

I haven't actually tried any scans.

However, the real-time service itself is terminating itself from time to time, giving this sort of thing in Event Viewer, System log:

The Windows Defender Service service terminated unexpectedly. It has done this 2 time(s). The following corrective action will be taken in 60000 milliseconds: Restart the service.

Only happening in the last day or so.

At the same time the Application log gets:

Faulting application name: MsMpEng.exe, version: 4.0.9200.16384, time stamp: 0x5010a938
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000
Exception code: 0xc0000005
Fault offset: 0x0000001b2291b30a
Faulting process ID: 0x1bbc
Faulting application start time: 0x01ce1d7b3018a577
Faulting application path: C:\Program Files\Windows Defender\MsMpEng.exe
Faulting module path: unknown
Report ID: c5998aa3-896f-11e2-bebb-f04da2547ed9

So I'd spent some time doing various checks of file system integrity and run a full memtest, but now it looks like the last update gave Windows Defender a poison pill

i noticed a couple of times yesterday that a pop up on the action centre flag saying turn on anti virus when i clicked defender it showed as protected , hopefully a new update will help

Yes, that's what prompted me to look in Event Viewer.

This forum has saved me from the pain of further investigation, resetting, reinstalling, hair pulling, swearing and making little effigies of people to stick pins in.

I, too, updated my definitions this morning, but no change to Defender behaviour. I've decided to get Bitdefender Total from Amazon and install that instead.

Many Thanks, indeed the latest definitions file does fix the issue...I wonder why Microsoft isn't pushing it out already!?

Thanks yeppe! The update must be downloaded and installed, an update via windows defender does not work.

 

[Kulana]

Thank you, Yeppe. I should have read your earlier advice more carefully. Downloaded, updated, ran scan and.......sorted.

Hi all, I've just done a clean install of Windows 8 and I updated the definitions via Windows Update. When I do a full scan or a quick scan, everything works. But I'm still on virus definition 1.145.1483.0. I've checked the Microsoft website and the latest defintions are 1.145.1490.0.

Strangely enough, Windows Update tells me everything is up to date.
