The avast program that constantly uses disks is a problem that may negatively affect your PC performance. If not fixed it could cause your software to slow down, or even fail to function. There are many ways to address this issue, including virus scanning as well as resetting your virtual memory, and running a fresh boot. Additionally you can also remove programs that you do not require and delete temporary files that are eating up RAM and CPU. You can do this manually or with a software like AVG TuneUp that can perform the task for you.
The change in the frequency of scanning could reduce avast’s disk usage. This technique will shut off background monitoring and checking, however it will decrease avast’s CPU usage.
It is possible to try updating the antivirus program if you are still experiencing high disk and CPU usage. To do this, you will need to start the Avast user interface by clicking the icon on your system tray, or by locating it in the start menu entry. Click Menu, then choose Settings from the drop down list.
You can view the current scans running on your PC by selecting Scan with Avast from the context menu when you right-click a file on the drive. Then, you can locate one that is using excessive memory and deactivate it by clicking the Stop button. You can then determine whether the CPU usage and disk usage has returned to normal.
