How to Fix High CPU Usage

Please note that this article is for Windows Users ONLY.

Have you recently noticed your desktop/laptop becoming more noisy lately? Have you noticed that your desktop/laptop has been generating more heat than usual? If you have and you've checked a Windows Program called Task Manager you will probably see a similar image below:



There maybe a few reasons why this is happening when you have TotalAV open or idle in the background.

Scheduled Malware Scanning

This is a feature that we introduced so people can do daily, weekly or monthly scans during an appropriate time for them. If you feel like you need to adjust these settings:

  • Open TotalAV
  • Go to Settings
  • Go to Antivirus Scans
  • See which settings you would like to change/disable

  • We strongly recommend enabling Scheduled Scans to ensure your system is frequently scanned and well-protected.

    Restart Your Computer

    Restarting your computer can help resolve high CPU usage from antivirus software by clearing memory, terminating stuck processes, and removing temporary files.

    It also ensures that software updates are fully applied and resets the system state, which can resolve conflicts or inefficiencies causing excessive CPU usage.

    Overall, a reboot reallocates system resources evenly, potentially reducing the antivirus software's impact on CPU performance.

    Uninstall and Reinstall {!TotalAV}

    By uninstalling and reinstalling TotalAV, this can fix the High CPU Usage with the program that you many have been experiencing prior, as it completely resets the program for you.
