100% Disk usage

Hi,

Since yesterday my disk usage is around 100% all the time. I tried uninstalling Avast then the disk usage returned to normal. After i installed the latest version of Avast from this website, the disk usage returned to 100%. Even when the scanners are disabled. How can i solve this issue.

OS: windows 10 home. Version 1607, build 14393.693

Kind regards,
Nebu
