avast’s constant use of disks is a problem that could adversely affect the performance of your PC. It can cause slowdowns in your applications and could cause crashes if it is not addressed. There are several methods to resolve this issue, including virus scanning and resetting your virtual memory and running a fresh boot. You can also uninstall any programs you don’t require and delete temporary files that consume RAM and CPU. You can do this by hand or with a program such as AVG TuneUp which will take care of it.
Modifying the frequency of scanning can reduce avast’s high disk usage. This will stop background monitoring and checking, but it should decrease avast service high CPU usage.
Try updating the antivirus software if you are still experiencing avast high disk and CPU usage. You can open the Avast interface by clicking the icon in the system tray or by looking for it under the Start menu entry. Then, click Menu, and select Settings from the drop down list.
You can view the list of scans that are running on your computer by right-clicking a file located anywhere on the drive and choosing Scan using Avast in the context menu. You can then find an active scan that is using too much memory and then disable it by clicking the Stop button. After that, you can test to see if the CPU and disk usage is back to normal.
