Windows Security identifies Powershell as Trojan. What do I need to do to resolve this issue?

I thought I solved this problem about 2 weeks ago. But unfortunately this issue has once again persisting where Windows Security will identify Powershell as Trojan. It keeps saying "Threat removed or restored", and what makes the whole thing strange for me is this same problem pops up at a fixed time at 2:04, 6:04, 10:04, and this on both AM and PM.

Detected: Trojan:PowerShell/TommyTech.C

Status: Removed or restored

This threat or app was removed from quarantine or restored to the device.

Date: 11/24/2024 6:04 AM

Details: This program is dangerous and executes commands from an attacker.

Affected items:

amsi: \Device\HarddiskVolume4\Windows\System32\WindowsPowerShell\v1.0\powershell.exe

When I go to hit click more, it sends me to this link (https://www.microsoft.com/en-us/wdsi/threats/threat-search?query=Trojan:PowerShell/TommyTech.C**)******and reads: Attention: We have transitioned to a new AAD or Microsoft Entra ID from the week of May 20, 2024. In case your tenant requires admin consent, please refer to this document located at Overview of user and admin consent - Microsoft Entra ID | Microsoft Learn and grant access to App ID: 6ba09155-cb24-475b-b24f-b4e28fc74365 with graph permissions for Directory.Read.All and User.Read for continued access. While the app may appear unverified, you can confirm its legitimacy by verifying the App ID provided.

By this point, you can say that I'm a bit of a tech illiterate. Because this is the part where I get stumped on as to what I need to do. If I can have someone give me step by step solution to the problem that I'm having, it'd be fantastic.

To thoroughly check for and remove any malware, please run a scan with Farbar Recovery Scan Tool (FRST) and share your logs.

Note: If you are using Edge, SmartScreen may initially block the download.

Click on the three dots next to the warning and select Keep => Show more => Keep anyway.

  • If your computer's language is not English, rename FRST64.exe to FRST64English.exe
  • Run the tool, leave the default settings, and press Scan.
  • Zip the logs, FRST.txt and Addition.txt, then upload to a cloud storage service like OneDrive, Google Drive or Gofile.
  • Post the share link.

    It looks like the task, ChromeUserAgentUpdater, that triggers the detection has been removed.

    That all looks good in the fixlog. Did you remove the proxy? Are there any related problems remaining?

    Thanks, It's working
