Having used Avast Antivirus on a number of Windows computers for many years, I can tell you that it does provide really good protection for your computers. It is one of the security products that adopted the web scanning practice very early compared to some other antivirus vendors. If you are looking for free antivirus protection then you can close your eyes and trust Avast Antivirus without thinking twice.
But the newer versions of Avast Free Antivirus scan not only for the malware and other threats, but they also scan for the PC performance. Now if Avast determines that your PC is slowing down for some reason – it shows notifications in the system tray icon just as it would show notifications when it has blocked malware infection.
It also suggests some ways to improve the PC performance and you can go through them if you want. But if you do not care for these performance improvement options from Avast, then you can disable this option in the settings. Here is how:
- Double-click on the Avast icon in the notification area of your Windows desktop.
- When Avast Antivirus window opens up, click on the Menu and then select Settings.
- From the left select the General category.
- Turn off Scan for performance issues from under the sub-category Smart Scan.
- Click on the OK button to save the settings.
After making these changes, Avast Antivirus will no longer scan your PC for slower performance and show any notifications to the effect. This performance scan is a part of smart scan and tells you about the various things that can slow down your system. It is able to find the junk files, redundant apps, inefficient system settings, obsolete registry settings and more. Removing these items can improve your system performance a little, but there are many other applications like CCleaner that can perhaps do this job better.
