Why is Avast Using So Much CPU? Unveiling the Reality
Avast has tried to optimize its software’s performance impact on system resources. While it may still use CPU resources during scans and real-time protection, the effect is often minimal compared to other antivirus software options.

There are several potential reasons why Avast antivirus software might be using a significant amount of CPU resources:

  1. Scanning processes: Avast regularly scans your system to check for viruses, malware, or other security threats. During these scans, it may use considerable CPU power to analyze files and processes.
  2. Real-time protection: Avast’s real-time protection monitors your system for suspicious activity or threats. This continuous monitoring can utilize CPU resources, mainly when it scans incoming files or checks running processes for potential threats.
  3. Updates and background activities: Avast periodically updates its virus definitions and software to stay updated with the latest security measures. These updates and other background activities can temporarily increase CPU usage.
  4. System specifications: Avast’s resource usage may vary depending on your computer’s specifications. Avast could have a more noticeable impact on CPU resources on older or less robust systems compared to more advanced hardware.

If you find that Avast is consistently using a high amount of CPU resources and it is significantly impacting your system’s performance, you can try the following steps:

  • Ensure that Avast is current: Keeping Avast and its virus definitions updated can help optimize its performance.
  • Customize Avast’s settings: Check Avast’s settings for options to adjust the level of scans or real-time protection. You can reduce the intensity of scans or limit the number of files scanned to minimize CPU usage.
  • Consider alternative security software: If the CPU usage of Avast remains problematic, consider exploring other reliable antivirus software options with lower system impact.

Remember that maintaining a balance between system security and performance is crucial. If you have persistent concerns about Avast’s CPU usage, please contact Avast support for further assistance.
