    Hi, I am having problems with my computer. Whenever I boot onto Windows, it starts with a message stating “Windows Defender error code 0x80093acf”¬†and it is asking for password.

    This is the first time I encountered such an error since I activated Windows Defender more than a year ago. The security program is updated regularly and is working fine since then. I really have no idea why I am receiving “Windows Defender error code 0x80093acf” each time I open my computer. Please help me.

    Thanks a lot in advance.

    Jane W.

    I can’t get into the system to perform a malwarecleaner. I’m stuck on fake page & can’t get past it. I’m know the scams. I’m not calling for help hoping you can suggest something? Thank you in advance.
