Windows 10: Powershell.exe virus

I have downloaded a virus that i believe is something to do with powershell as when I open my laptop it opens a blue screen tab labeled powershell.exe. When I googled how to delete it my serch automatically changed to 'classic cars'. I have downloaded avast antivirus, however it picks up nothing when I scan.This is slowing down my laptop and I have had the virus for a very long time, is there any way to get rid of it without reseting everything?
