If you run MSE as AV program, that includes Defender. In fact it is the same process - MsMpEng.exe

 

[amir tava]

im sorry i dont understand what your trying to tell me..

 

[whs]

What is your Antivirus Program - is it MSE (Microsoft Security Essentials)?

 

[amir tava]

no its Kaspersky Internet Security 2012

 

[whs]

OK, I am not a Kaspersky expert. But I suspect that Kaspersky has shut it off because they have a similar function. But I am not 100% certain of this. Wait until some Kaspersky expert comes on.

 

[amir tava]

you might be right should i give a try to unistall Kaspersky Internet Security 2012 and see what happends?

 

[whs]

I would not do that. Kaspersky is an excellent AV program and protects you better than Defender. Besides, if they have shut defender off, it may not automatically come on when you uninstall Kaspersky.

 

[amir tava]

so what are you suggesting me to do fix the problem?

 

[whs]

I don't think there is a problem. Defender and Kaspersky may be mutually exclusive. But wait until a Kaspersky expert can confirm that. If I am wrong, we can see what can be done - e.g. a Repair/Install.

Since you are using a good AV and their might be a conflict you could always just turn Windows Defender off

 

[Ztruker]

I found this: Troubleshooting Windows Defender Conflicts

whs is correct that Kaspersky disables Defender and apparently this goes wrong sometimes. A fix for the error is included at the link.

 

[amir tava]

@ztruker thanks a lot ill come back with the reuslt ill try it out!

 

[amir tava]

@ztruker as i mention before i can't see Windows Defender list in my services list
Windows Defender services is missing.....
i just want Windows Defender work like a normal that's all

As stated in Ztruker's link, Kapersky disables Defender just like MSE does. The fix given is only for a recurring Windows Defender 0X80070006 error code at boot, not a 0x80070424 missing Service when you open Windows Defender.

Kapersky has disabled and likely hidden Defender as intended, just as MSE does by Disabling it. It isn't needed any longer when either of those AV's are engaged.

Well since you confirmed Kaspersky disables it why not leave it disabled. I assume there's a good reason for them to disable it in the first place. It must cause a conflict between the 2 programs.

Not to mention it doesn't much Defend. :huh:
