I thought this was just a MS problem but its becoming a real pain.
With nothing running ( that Im aware of ) the system just seems slow. I have a constant CPU usage of around 70% and have no idea why.


Everything is up to date but I am at a loss as to where to start looking.
When I check the running processes, I see sytem monitor at about 25% Firefox-bin similar and plugin-container also about 25-30%.

Has a recent update caused any issues with firefox or is something weird just going on with my system?
TIA.
