Hello David, 

We will check and help you to resolve it.

  • Could you please confirm whether you are using AVG Anti-virus free or paid subscription?
  • Also, please share us the screenshot of task manager which shows high CPU usage. 
  • Does CPU usage always shows high or only during startup?
Keep us updated. Thanks in advance.
