Windows 10: TiWorker.exe is intentionally hiding itself from being seen.

I knew TiWorker.exe is associated with Windows Updates, but I wonder if there is a trojan disguised as TiWorker.exe.


I noticed sometimes my Task Manager would be shut without me closing it, after reopening it, TiWorker flashes past and disappear from Task Manager. After a little investigation, I found that every time Task Manager shuts suddenly, I would see TiWorker just for a second after reopening it, TiWorker won't show up if I have Task Manager on but it would force shutdown Task Manager when it runs. It appears TiWorker is trying to run every few minutes, So the conclusion is,TiWorker —— or the trojan that's pretending it —— is intentionally hiding from being seen and being traced.


It always occupies around 30 - 40% CPU usage, and never stops, despite the countless restart attempts I tried.


I took this screenshot by setting Task Managers' refresh speed to "pause", so I could see what's up with my PC immediately after the moment the program was run andTiWorker will not be able to disappear without a trace. However, when I tried virtually any operation on it, including open the location of the thing, it just doesn't work.




Another thing is, TiWorker doesn't pop up whatsoever when my computer is offline, it is only in effect when I'm connected to the Internet.This along with the high CPU usage raises concern about if it was mining my CPU when I was not paying attention.


No virus found in anti-virus software


My whole weekend was haunted by this, please, anyone give an explanation. Is it malware, why are this thing's deeds so deceitful, or why does this thing even exist?


My greatest appreciations.

Hi,



Thank you for writing to Microsoft Community Forums.



We understand your concern and we appreciate you for the detail information with the screenshot.



The TiWorker system process is related to Windows Update. This is one of the critical process included on in Microsoft Services and must not be mistaken for any malware issues. If there are any updates happening or if the computer
is scanning for any update release, this system process may use resources on your computer, the reason why you see it has high CPU usage under task manager.



However, we would suggest you to perform these steps and check if that helps you.



Method 1: Run the System Maintenance troubleshooter.

1. Right click at Windows Start menu icon and select Control Panel.
   
2. Set the View by to:
   Small icons.
   
3. Click on Troubleshooting,
   then click on View all from the left pane.
   
4. Double click at System Maintenance.
   
5. Press Next and then follow the onscreen prompts to run the System Maintenance troubleshooter.
   

Method 2: Provide file exclusion in Windows Defender.

1. Type in Windows Defender in Windows search.
   
2. Select Virus & Threats protection from the left pane.
   
3. Click on Manage settings under
   Virus & Threats protection settings.
   
4. Scroll down and click on
   Add or Remove exclusions under Exclusion.
   
5. Click on the + sign beside
   Add an Exclusion.
   
6. Select file and go to this location:
   C:\Program Files\Windows Defender\msmpeng.exe
   

We await your response.

how to effectively hide or disable the taskbar?

Hi,



Did you try the “Auto-hide the taskbar” option from Taskbar properties?



If you have not tried it, I would suggest you to follow these steps and auto-hide the taskbar:

• Right click on Taskbar.
• Click on Properties
• Check the box Auto-hide the taskbar.
• Click on OK.

Hope this information helps.
