Windows 10: I have an @echo script running on a computer daily, want it OFF

I found something that look like it may pertain to shutdown. In C:\Windows\Tasks, there's a file At1, which isn't in scheduled tasks.....
upon opening with notepad+
<!-- Copyright (c) Microsoft Corporation -->
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
version="5.1.0.0"
processorArchitecture="x86"
name="Microsoft.Windows.Shutdown"
type="win32"
/>
<description>Windows Shutdown and Annotation Tool</description>


<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">

/>
</requestedPrivileges>
</security>
</trustInfo>
</assembly>


looks like something shutdown related to me... will delete that file and set time to 8:59 again.

UPDATE:
Still shutting down...

 

It mentions shutdown so could be it but the name AT1 seems to ring a bell with some kind of virus / malware.

It may be worth running a scan with malwarebytes Malwarebytes | Free Anti-Malware & Internet Security Software

Downadup is the virus, it would be worth runing a virus check to be sure

 

Oh No! tbh, I think tomorrow is the day to 'redo' that computer and check the rest of the household computers!

Thanks for all your help throughout Jamie!

I will update thread after I do virus scan though.
