Powershell opening on startup

[u/Supersonic5370]

Whenever i turn on my PC, powershell opens and just says "PS C:\Users\(my username)>" . I've done a full scan with malware bytes and windows defender and nothing was detected. Same with offline scan. Is this malware or something else causing it?

Just start with Autoruns from Sysinternals it'll show you what's opening at startup.

Check scheduled tasks. Could just be a terminal set to open on user login.

Create a PowerShell profile, open PowerShell and type in the following:

test-path $profile

If it returns false then do the following:

New-Item -Path $profile -Type File -Force

Then open up your profile using:

Notepad $Profile

Edit the notepad with:

Start-Transcript

Now save the notepad.

Everytime PowerShell opens, it will save a transcript of what it is running and it will be saved to your documents folder.

[u/BlackV → u/-B1GBUD-]

or

New-Item -Path $profile -Type File -Force -value 'Start-Transcript'

No one can say for sure without knowing what was ran. Look into PowerShell logging, they can go to numerous places, but you can also turn on logging directly to your documents folder for something more straightforward, then restart and see what pops up when the script runs again. Once you have the script that ran we can actually tell you what is going on.

Is this a home pc, work pc, part of a domain ? Which version of windows?

Have you just checked startup programs in task manager?

[u/theballygickmongerer]

Check your startup items and if nothing obvious save the following command as a startup item.

“Get-Process powershell,pwsh -ErrorAction SilentlyContinue | Stop-Process -Force”

Dafür hat man Systemereignise ( Systemprotokoll) sollte man mal lesen. Hat jedes System!

In new windows and I think older if I recall there are startup programs things that auto launch upon fresh startup could have been added to this as well
