Windows 10 Powershell keeps booting up when i turn on my computer

I've had my computer for a little bit over a year, and until recently every time I boot up my computer Powershell starts up and sits there for like 10 seconds then goes away, so i did what a regular person would do and checked the Startup tab on Task Manager, Powershell wasn't there. I go and scan for a virus on Avira, thinking it was some sort of virus, but nothing showed up. So i am lost and don't know what to do.
