Thanks, I have used avast one in past. It was okay, but processor choked to 100%.
If you experienced high CPU usage with Avast in the past, it's possible that it was conflicting with other software or there may have been an issue with your specific system configuration. In that case, you can try some alternative lightweight antivirus options that may have a lower impact on your CPU usage:
1. Windows Defender (Microsoft Defender Antivirus): As mentioned before, Windows Defender is a built-in antivirus solution in Windows 11. It is designed to have minimal impact on system resources, including CPU usage. It provides real-time protection and regular updates from Microsoft.
2. Avira Free Security: Avira is known for its lightweight nature and efficient resource usage. It offers real-time malware protection, web protection, and a VPN for secure browsing. Avira has a small footprint and should have a lower impact on your CPU.
3. Panda Free Antivirus: Panda is another lightweight antivirus solution that offers real-time protection against malware, phishing, and other threats. It uses cloud-based scanning to offload some of the processing to the cloud, reducing the strain on your CPU.
4. Sophos Home Free: Sophos Home Free is a lightweight antivirus program that provides real-time protection against malware and other threats. It has a minimal impact on system resources and offers additional features like web filtering and parental controls.
Remember to uninstall any previously installed antivirus software before installing a new one to avoid conflicts. Additionally, keeping your operating system and software up to date, practicing safe browsing habits, and regularly scanning your system for malware will further enhance your overall security.
