Know yes I know this problem has been solved to death and I want to get some stuff out of the way.1. This is a brand new laptop I just bought from Bestbuy I received it yesterday, the 30th of January2. I have no 3rd party antivirus installed3. I have tried doing the deleting registries thing, in fact I did it twice but after the restart it was the same as before4. Just in case it helps, I have a Lenovo Slim 7 ProX 14ARH7Please help, this is driving me crazy

Windows defender false positive - forced to allow threat

Windows defender has started to identify C:\Windows\System32\mshta.exe as a threat [normally reported as a Trojan Powessere.G]. I use mshta.exe to run an hta custom MsgBox - I have been hoping to keep using my current CustomMsgBox tool [batch file calling a vbs-hta file] until later this year when I hope to have had enough time to replace it with a PowerShell alternative.

Windows defender's notification lets me "allow the threat" but that seems to me to be a bigger security hole than is necessary - it will now ignore a potentially real intrusion when all I want to run is a genuine Windows component. My immediate problem is fixed but I would prefer to fix the false positive using the exclusions list.

I cleared the 'Allowed threats history' so I could use the exclusions list instead. I added C:\Windows\System32\mshta.exe to the file exclusions list and I checked that it had taken properly by checking the exclusions list both in the UI & in the Registry. But the exclusion made no difference, it continued to detect and block the exe.

I have repeated the attempt several times [by clearing the allowed threats list & exclusions list beforehand] and the results are the same every time
- allowing the threat works,
- using the exclusions list has no effect.

I studied the relevant tutorial but have not spotted an error in what I have been doing - Add or Remove Windows Defender Exclusions

Does anybody with experience of using the exclusions list to counter false positives have any suggestions for me?

Virus and Threat Protection "Limited access by IT Admin" WINDOWS 11

I cannot access the virus & threat protection section of Windows Defender and get a popup that says my IT Administrator has limited access. I'm on a personal Desktop running Windows 11 Home, Version 22H2, OS build 22621.2861. I have tried Hkey_Local_Machine\Software\Policies\Microsoft\Windows Defender\Policy Manager and default is the only thing there. I have also tried all of this (Settings -> Go to Accounts -> Select Emails and Accounts, if there is a work or school Email listed there, remove or disconnect it. Select Access Work or School, if there is a work or school Email listed there, remove or disconnect it. Close the Settings App and restart (not shut down) your Computer.) but I do not have a work or school email/account linked with this device. Also I have reset my computer and do not have a 3rd party antivirus installed.

Can someone help me I am at a loss and it is sort of time sensitive as this is a computer for my father as a present and I am leaving the country soon.

 

Windows Defender/Security - no option to "Allow" potential threats?

If you want to control what does defender do to threats you can do it trough GPO in the following location: Computer configuration\Administrative templates\Windows components\Microsoft defender antivirus\Threats Here configure option: Specify threats upon which default action should not be taken when detected Threats are categorized by level, you assign default action per threat level.

EDIT: Btw. to open GPO (Local Group Policy) follow these steps: 1. click on start button 2. type: gpedit.msc 3. right click on gpedit.msc and run as Administrator
