If you are looking for a way to fix the Kaspersky Lab launcher’s high CPU usage on Task Manager, I will tell you everything you need to know about this issue.
This issue has been around for more than one year, but so far, Kaspersky still needs to release a fix and give an official explanation of why this happens. Here is what I found:
Kaspersky Lab launcher uses so much CPU because Kaspersky runs an automatic scan in the background whenever your PC is inactive. You can fix this issue by disabling Kaspersky’s Background scan.
To disable the Background scan, follow the steps below:
- Open the Kaspersky main window, and click on the Scan button:
- In the Scan window, click on the Settings icon in the Background scan tab.
- Under Background scan settings, turn off Background scan.

The Best Method to Fix Kaspersky Lab Launcher High CPU/Disk Usage
The best way to fix this issue and to free up your PC resources (while avoiding Kaspersky’s lackluster customer support) is to uninstall any Kaspersky application.
You don’t need Kaspersky to keep your PC protected. Windows Defender, plus a powerful anti-malware tool, offers better protection while using fewer resources.
(I’ve written a whole article on why you don’t need Antivirus software when you have Windows Defender.)
Most Redditors also share this opinion:
To complement Windows Defender protection while having manual scans, download Malwarebytes.
Download: Malwarebytes
(I’ve written an article on how to run Windows Defender and Malwarebytes at the same time without conflicts, make sure to check it.)
Conclusion
The Kaspersky Lab’s high CPU usage is likely caused by the Background scan feature of the Kaspersky application.
Until now, Kaspersky didn’t release an official fix to the Kaspersky Lab’s high CPU usage. So, you can only fix it by disabling the Background scan, as I explained at the beginning of this article.
The recommended solution, however, is to uninstall Kaspersky. Use a combination of Windows Defender and Malwarebytes for better protection and a faster PC.
