Urgent Help Needed: Possible Win32/Expiro Infection

I am experiencing repeated alerts from Windows Defender about Virus: Win32/Expiro, Virus: Win64/Expiro.DA!MTB and Virus: Win32/EK!MTB. Every time I try to open Defender, it closes immediately, and attempting a Windows Defender Offline Scan results in an error stating the system path is not specified. I am running a 64-bit version of Windows 10/11, and the virus seems to be affecting critical files in System32.

I am concerned that my system may be actively infected, and normal scans inside Windows are being blocked. I need urgent guidance on safely scanning, removing the virus, and recovering my system without further damage.

Thank you for your assistance.

    If Microsoft Defender Antivirus and Defender Offline cannot find any threats or finds but cannot remove threats, there are various secondary opinion scanners which can be used to supplement your existing antivirus.

    I provide a more detailed list of malware removal tools with scanning instructions in Supplementing your Anti-Virus Program with Anti-Malware Tools (Post #4)...just scroll down near the bottom of that post.
