By reducing the frequency and timing of scans, you can minimize the impact on system performance while still ensuring regular protection against malware.

Exclude Files and Folders

If certain files or folders on your computer are known to be safe and don't require scanning, you can exclude them from the scan to reduce resource usage:

• Open Windows Security and navigate to "Virus & threat protection."
• Under the "Quick scan" section, click on "Scan options."
• Click on "Add or remove exclusions."
• Click on "Add an exclusion" and choose whether to exclude a file, folder, or file type.
• Select the specific file, folder, or file type you want to exclude from scanning, and click "Open."

By excluding files and folders that are not a security risk, you can reduce the scanning workload and improve system performance.

Optimize Windows Defender Settings

You can also optimize various settings in Windows Defender to improve its performance and reduce resource usage:

• Open Windows Security and navigate to "Virus & threat protection."
• Under the "Virus & threat protection settings" section, click on "Manage settings."
• Toggle off the "Real-time protection" option temporarily if you need to perform resource-intensive tasks like gaming or running demanding applications. Remember to toggle it on again afterward to ensure continuous protection.
• Under "Automatic sample submission," consider selecting the "Only send samples automatically when I click 'Send'" option to reduce network traffic and resource usage.
