Whenever I start my computer, this box pops up. Is it a system error/ a virus? WindowsService.exe

It's a coin miner malware. Please run the following commands to remove it.

From the admin Command Prompt, run these four commands:

del "%LocalAppData%\Updates\Run.vbs"

schtasks /delete /tn "\Window Update" /f

schtasks /delete /tn "\Windows Service Task" /f

rd /s /q "%LocalAppData%\Updates"

Pls post a screenshot of the output window.

Note: Microsoft Defender needs to be fixed after doing the above. The malware would have deleted Defender in most cases.

And then do the following;

• Download Farbar Recovery Scan Tool (FRST64.exe) 

• Run FRST64.exe and click "Scan".

• Upload the two logs, FRST.txt and Addition.txt, to your OneDrive and share the link here.

I tried the commands you mentioned

The malware seems to have disabled UAC and deleted the Security Center. Please post the Farbar scan logs, as requested in my previous post.

how can i do so? The pop up is gone I tried different method from different post but now the only problem is of window security center service!

Instructions are in my post #1.

BTW, which methods did you try?

This method

How to send log?

That method can be used as well. But since you ran those commands already, Autoruns won't list those two scheduled task entries. they're already gone.

now no notifications and pop ups are coming but windows security is blank?

Let me ask one more time. Please upload the Farbar scan logs. See Share OneDrive files and folders - Microsoft Support: https://support.microsoft.com/en-us/office/share-onedrive-files-and-folders-9fcc2f7d-de0c-4cec-93b0-a82024800c07

If you don't want to upload it, then you may do the following

1) Download Malwarebytes and run a scan.
