Windows 10 W Defender popped message that my pc is disabled detected Trojan spywareup message

Hello, thank you for using Howly.
The “Threat Detected: Trojan Spyware” fake error message is a scam that pretends to be from Microsoft to trick you into thinking that your computer has crashed or that a virus has been detected. It does this to try and scare you into calling one of the listed numbers to receive support.

Could you specify, what page are you referring to?

if the PC freezes up, open Task Manager Then white box saying Win Def Sec Center

Could you try to restart your computer, please?

Probably, it was like a link or advertisement which you followed.

If it happens next time, please, follow these instructions:
1. Open the “Task Manager” by pressing the Ctrl + Alt + Del keys on your keyboard and then selecting Task Manager.
2. Scroll through the list until you see your web browser’s process and left-click on it once so it becomes highlighted. Once you have selected the browser’s process, click on the End Task button as shown in the image
3. Your browser window should now be closed. The next time you open your browser, do not allow the browser to open the last opened page.

Thanks, you too!
Please feel free to contact us at any time. We'll be happy to help you. Have a nice one, Alice!
