Windows Defender: Error Code: 0x80080017

Split from this thread.

Windows 8.1

The Action Center flag in the notification area has a red X. In Action Center it says "Windows Defender is turned off".

When clicking "Turn on now", the Windows Defender app opens and I seemingly can do a manual quick scan.

Definitions last update is from this morning, but I cannot manually initiate an update. The error is  "Virus and Spyware definitions couldn't be updated. Check your internet connection ....". "Connection failed".

However my Internet and Network connections work as intended.

I have gone thru each single step outlined in Problems starting Windows Defender ..., to no avail.

CBS.log (sfc /scannow) indicates the following errors:

REPOSTING...

1. Did you (a) uninstall the McAfee free-trialware AND THEN (b) download/run the McAfee Consumer Products Removal Tool & reboot (c) BEFORE you installed ANY updates (including KB2919355)?

  • Fact: McAfee (and Norton) applications are notorious for not uninstalling (or upgrading) cleanly. The "leftovers" may be playing a role here.

2. When & why was IObit Malware Fighter installed? Is it the free or paid version?

<QP>
There's absolutely no reason to buy or even try IObit Malware Fighter...It doesn't function as an antivirus and doesn't effectively fight malware. In testing, it reported seven thoroughly infested systems as perfectly clean. Avoid it.

3. Do you have backups of ALL the changes Advanced SystemCare has EVER made to the computer? [1

===========================================================
[1] Injudicious use of registry cleaners may be playing a role here. TIP: If you ever again think your Registry needs to be cleaned, repaired, boosted, tuned-up, cured, tweaked, fixed, maximized, "swept" or optimised (it doesn't), read this article (and related links cited therein) then draw your own conclusions.

Answer

Windows Defender Service is running.

The Windows Defender reports "Definitions last updated" just a few hours ago and virus definition version 1.195.3756.0 

However when I hit the button for manual update I get an error "This app couldn't check for.definition updates. Check your Internet connection".

And in the action center I'm still stuck with this:

There you are... Did you mention IObit Malware Fighter in this thread before? Well, I guess you did: You told PA Bear on April 13 that Advanced System Care (ASC) was installed.

The real-time protection components of both these programs might be the culprits.

Please remember that Windows Defender on Windows 8.1 will turn off its real-time protection automatically once another security program is detected as installed. So no matter whether ASC's real-time protection (It's supossed to use BitDefender's antivirus engine technology) is ON or Off, Windows Defender's real-time protection will be OFF in Windows 8.1, and this is what Action Center is telling you.

Would suggest you now proceed to uninstall 'everything' IObit, i.e., ASC, Malware Fighter, Driver Booster, etc..

Also, please reply to PA Bear's question concerning the removal of potential leftovers of your McAfee free-trialware. If you didn't run their 'Consumer Products Removal Tool' when you first uninstalled the product from the Control Panel, do it now.
