Hi vichetsim

Powershell should not be running in the background by itself, that is generally a sign of a problem with your PC . . .

You need to find what is running in Powershell . . .

First let us rule out malware . .

You should run a scan with the free version of MalwareBytes to see if it can find any malware that may have escaped Symantec

https://www.malwarebytes.com/

When that scan completes, restart your PC then you can uninstall MalwareBytes . . .

Then, if Powershell is still hogging your resources, look for any reference to Powershell on your Startup processes and delete any you find . ..

Task Manager and indeed Msconfig offer only limited control over Startup items . . .

Click the link below to download a small free utility that does not require installation

When the file downloads, unzip it.

Depending on your system, run Autoruns or Autoruns64 as Administrator

With that utility, you can right click and delete any startup item in Windows

Check in the initial lost and also on the logon tab for any reference to Powershell, right click and delete any you find . . .
