Windows 11 Defender unable to scan and other issues with it

The_Nephilim · May 13, 2023

Hello Everybody,

I just installed Windows 11 Fresh install from a mediacreation USB Install. I have had Win 11 for about a month now but this latest reinstall. and I am having issues with Windows defender.

I got it to a point where it is at least showing it is on, Currently I am unable to do any type of a scan it just does not Run a scan.

I have tried updating windows and DISM, SFC/Scannow fixes all have not fixed it. I also tried to repair it in the apps section. but nothing has fixed it and I am unsure why the scan ability is not working.

I have my system specs and here is my Win 11 version:

Version 22HS(OS Build 22621.1702). like I said this is a brand new fresh install not an image and I also wiped my M.2 drive with a nvme delete built into the Mobo and using Parted Magic..

Not sure what else to add but I am really trying to figure out why the scans will not scan, perhpas I have a malicous virus or worm??

Execute the following PowerShell command to re-register Windows Security app.

Code:

Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SecHealthUI*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Did you open the PowerShell with an administrator privileges?

IS that script thingie 3 parts or do I copy the entire thing into PowerShell and I am getting some hits in Maleware Bytes wierd as this is a fresh install. could the windows ISO that I used be corrupted somehow?

FreeBooter · May 13, 2023

You need to copy and paste the entire code to the PowerShell and press Enter key.

OK I did that the first time and got multiple red messages. I am also getting trojan hits called "Torjan.FakeMS.ED?? any idea what that is?

The_Nephilim · May 13, 2023

I ran that command no problems this time I think I missed the last bracket :) Also I found a few trojans and just got back from a reboot but Defender is still not able to run a scan and I am on a clean boot..

Trojan.FakeMS

Trojan.FakeMS is a generic detection for Trojans that try to pose as legitimate Microsoft files.

In this guide, i will show how to fix typical issues if you cannot open the Windows Security in Windows 10 and Windows 11.

As you can see from above video PowerShell command works but i have no idea why it does not work for you.

Yes no go. I also am getting a errer when running Power shell

Have you executed Sfc /Scannow command?

Windows 10 DLL File Information - atl.dll

windows10dll.nirsoft.net

You should try in-place upgrade your settings, files and programs won't be affected by it.

Yes I had stated all I did in my OP..

I think I have a corrupted ISO from my own doing. I am going to go on another PC and get the Media tool from microsoft. I appreciate all the help but I think this install is beyond saving and corrupted real bad..

I understand, good luck!

Hello Everybody,

from a mediacreation USB Install.

Was this from the MSN site, an official download ?

May be a corrupt download. Consider another clean install and fresh download.

The_Nephilim · May 15, 2023

Yes it was the official MS site and my trouble began with trying to get a slimmed install of Win11 and I used NTLite and this other program from CTT which I think had a bad link to a nefarious copy of one of the softwares I could auto install..

I finally found a hidden partition on the flash drive that I was using during all this. I did delete it but when I was Formatting the flash drive it failed with a error -1 error so I ditched it and I reinstalled Win11 and all seems fine now..
