possible incorrect DEP warning, persistent DEP Warning in Avast Free Antivirus on Windows 11

I am using Avast Free Antivirus on a Windows 11 computer. Avast Smart Scan repeatedly displays the following warning:

“Malware or other threats could be running in your PC memory. Turn on Data Execution Prevention to detect malicious codes (it will turn on after restart).”

However, I checked the Windows security settings and found the following:

  • Windows Security → App & browser control → Exploit protection: Data Execution Prevention is set to “Use default (On).”

  • PowerShell command Get-ProcessMitigation -System: DEP Enable is NOTSET, and Override DEP is False.

  • Command Prompt command bcdedit /enum {current}: nx is set to AlwaysOn.

  • Windows Security reports Avast Antivirus is turned on.

  • Avast Firewall is also enabled.

  • Avast’s Viruses & malware scan section reports “Looking good.” No specific virus, malware name, or suspicious file is identified. The only persistent warning is the DEP warning.

I have not changed Windows boot settings or disabled any security protections.

Could you please investigate whether this is a false warning or a compatibility issue between Avast Smart Scan and Windows 11 DEP settings? Please advise how to resolve it without purchasing Avast Premium Security.

Thank you for your assistance.
