[Help] "Threat service has stopped" error on Windows Defender — even after a 100% clean USB wipe/reinstall following a malware incident

TL;DR:

Fell for a fake "human verification" clipboard scam (Win + R -> Ctrl + V -> Enter). Decided to completely nuke the drive and reinstall Windows 11 from a fresh USB. After a total partition wipe and running all Windows Updates, I opened Windows Security to run a scan, but I'm getting: "Threat service has stopped. Restart it now." How do I fix this, and is there any chance malware survived a full partition wipe?

  1. What Happened Initially

I fell for a malicious website prompt that asked me to verify I was human by pressing Windows + R, pasting (Ctrl + V), and hitting Enter.

Realized immediately what happened and closed it, but the malicious script had already executed, leading to a broken Windows Defender and malware alerts (like Wacatac / infostealer).

  1. The Clean Install Process I Did

To be 100% sure the system was clean, I performed a full wipe:

Created an official Windows 11 bootable USB using Microsoft’s Media Creation Tool on a separate, clean laptop.

Booted from the USB on my PC (Motherboard: ASUS TUF X670E-Plus WiFi).

Selected Custom Install, deleted every single partition on the drive until only "Disk 0 Unallocated Space" remained, and installed Windows directly onto that blank NVMe SSD.

Set up Windows and ran Windows Update through multiple restarts until it showed "You're up to date".

  1. The Current Problem

Now, on this brand-new, clean installation with nothing else downloaded yet:

When I open Windows Security / Virus & threat protection to run a quick scan, it displays:

"Threat service has stopped. Restart it now." (with a "Restart now" button).

Clicking the button either fails or the error persists / scan won't run properly.

  1. My Questions for the Community:

Given that I completely deleted all partitions to unallocated space using a clean USB installer, is the initial malware 100% gone?

What causes this "Threat service has stopped" glitch on a fresh Windows 11 installation after Windows Updates?

What is the most reliable way to force-restart or repair the Defender service so Windows Security works normally?

Thanks in advance for the help—I just want to get this sorted and use my PC in peace!

Does anyone know the exact episode this shot of Raoh and Kokuoh is from? I haven't been able to track it down.

First time watching the 1995 movie. I liked it, but... was that it? (NO SPOILERS)

Hey everyone,

I just finished the 1995 Ghost in the Shell (my first GitS experience). While I thought it was good, my immediate reaction when the credits rolled was: "Wait, is that all?"

It felt way too short. Honestly, it felt more like a single episode of a series or just one chapter of a manga rather than a complete movie. The ending felt abrupt and a bit anticlimactic.

To explain how it felt: imagine being given a taste of an incredibly delicious meal, only to have the chef yank the plate away before you can get full. I wanted the main course, but it feels like I only got the appetizer.

  • Is it normal to feel this way after the '95 movie?
  • Does the rest of the franchise step up and serve the "full meal" I'm looking for?

Please: absolutely NO SPOILERS for the rest of the series!
Just wondering if my reaction is common.

Thanks!

Movie vs. Manga: Best way to experience Akira for the first time?

Hi guys,

I'm finally ready to dive in, but I want to have the best first-time experience. Should I watch the movie first, or start with the manga?

I'd love your (spoiler-free) recommendations on which path to take and why!

Thanks!

Edit:

A huge thank you to everyone who commented and shared their advice!

I ended up watching the movie first, and wow, it is definitely a masterpiece. It was such an awesome experience, but the story totally hooked me and left me wanting more from this universe. I really need to know what happens next, how the characters develop, and where the story goes from here.

Because of that, I will definitely be reading the manga next. I can't wait to get my hands on the books!
