I have a Toshiba Satellite running Win 10 with the latest update and Norton 360. At times programmes are unresponsive for some seconds. After startup but without running any programmes Task Manager shows spikes up to 100% of very high CPU and disk usage. This is mainly caused by powershell 32 bit which starts, spikes and disappears all the time. I have disabled powershell but it has not stopped it appearing and disappearing from the list of processes. Is this normal? I might be incorrectly attributing unresponsive programmes to powershell activities.
I have scanned, using Norton, for security issues but nothing has been revealed.
There was a similar question on this topic some years ago but the thread closed before a solution was posted. Can anyone enlighten me please?
