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

[Santy]

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.

Some software use it to check for updates such as Lastpass. You could run procmon in boot logging mode, reboot and once you see the popup reopen procmon (this will take awhile) and review the output to see what launched powershell. Alternate would be download sysmon and install it as a service and reboot, it should log in the event log every process create.
