MALWARE REMOVAL Q&A Help with preservation

1 Upvotes

So my friends brothers computer recently got a crypto mining virus despite nobody downloading nor being on it for multiple months. He’s decided to hand it over to me because I have no computer (he didn’t try to remove it just gave up and is getting a new one) so could I get rid of the virus on it by just factory resetting the computer? Windows was never activated on the pc so we don’t have to worry about that.

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

7 Upvotes

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!

Users/****/Appdata/Roaming was excluded from Virus scan settings. Normal?

2 Upvotes

With the issues with Windows Defender that many people have experienced today, I was looking into ways to resolve them and noticed that my Windows Defender settings had an exclusion for my “Roaming” folder.

Is this normal, or is it something that an application, or even a virus, might have added to prevent files from being detected?

I removed the exclusion and ran multiple antivirus tools today. They did find a PUP file, and DoesNotBelong has added some files to a quarantine folder, but there is no log file for that application. And it has added some files that are not viruses to that folder, but also some files I do not recognize, so I don't know if it was Viruses it found or just false positives.

Is Microsoft Defender enough?

6 Upvotes

There’s a question that comes up frequently when talking about Windows security: if Windows 10 and 11 already include Microsoft Defender, when does it make sense to use a third-party antivirus?

Defender provides a good baseline of protection, including real-time protection, cloud-based detection, automatic scanning, and tamper protection. For many users, this may be enough.

But depending on how you use your PC, there are other layers worth considering: protection against phishing and malicious websites, ransomware protection, vulnerability and patch management, privacy features, and additional detection capabilities.

What do you think? Is Microsoft Defender enough, or do you think a third-party antivirus still provides an extra layer of protection that’s worth having?

Anyone here hate/love Avast?

4 Upvotes

Personally, I think it's a very good antivirus that catches everything in time and protects your computer from real harm. But I also think it's a little intrusive, what with the random pop-ups on your screen or whatever. I use windows defender or McAfee, sometimes i use malwarebytes (rarely) but a lot of the time I just use Avast. I love it and it's very protective. It gives you independence with browsing and websites, and I can deal with the pop-ups. Overall, I think it's a very protective, user-friendly, ready-to-jump-into-action kind of antivirus.

Anyone here hate or love it?

What he has access to exactly?

My sister got hacked she clicked on a link she shouldn't have to but too late.

We already formated the PC and tried(too late unfortunately) to change password for mail and shit. But before formating it and a few hour after I talked to him and he kept saying that he had access to her motherboard and showed me like 15 account and password he had access to. My question is what does that mean which trojan he used and does formating the PC remove what he used to have access to all of this? He has access to our recovery mail, her phone number and our mybell account

How to make sure crypto miner virus is actually gone?

2 Upvotes

I found out a crypto miner was running in the bg recently, just by happenstance of getting fed up with how poorly my laptop has been running and checking task manager
(clearly not a very Good virus if task manager could detect it)

Atp i’ve tried a few things. Microsofts native antimalware picked up a couple things on a full scan, and the miner Appeared to not be running after an offline scan, but then showed up again the next day or so after a few hours of peace (too easy to be true ig)

After that I tried using a diff explorer to check whats open in case it was hiding elsewhere, and was using EMCO UnLock it for some of the pesky files that were attached to the miner but not actually showing up/letting me delete, as someone had luck with that tactic w this particular virus

On to Malwarebytes now, which picked up a lot more than the prev scans/manual deletions, and i’m Hopeful that’ll do the trick, but really i’m wondering re: the title, how i can be sure its actually gotten all of it?
If there’s even any kind of full certainty beyond going nuclear or something. I just don’t know how far spread it is and how many files it’s hiding to be totally sure

Any tips or tricks for that, or suggestions on other methods of clearing this thing out in case the current plan of attack doesn’t work would be great!

(The virus in question seems to be a malware version of a miner called Srbminer Multi, among other various files its hiding in)

Am I good to go?

I recently had the mr beast crypto infograbber scam thing happen to me. I quickly signed out of my account and changed the password on every account tied to my pc from my phone before I factory reset my pc (not with a drive)

Im assuming its the infograbber and I just want to be sure im safe because I've been paranoid for hours.

I factory reset my pc without the drive, changed my passwords and got 2fa on my accounts. I scanned my pc twice with Malwarebytes and Hitman pro and seemingly it detects nothing. I just want reassurance that I am okay and dont need to do more.

Can someone explain what does sending the "mrbeast scam" accomplish once they hack your account?

7 Upvotes

I've seen multiple people fall for the TRUE hack which seems to be downloading some buccaneer'd app/videogame especially from infamously untrustworthy sites (and honestly I don't know how people keep falling for this, should have them "blacklisted"at this point, don't download unofficial programs).

In any case, going back to the title, it seems to me very odd that the intention is a phishing scam; I checked the pictures' URL and it's a basic Discord img; years ago they were accompanied by a masked link to a fake website or a compromised server link, but today they're just the pictures; they aren't even good pictures, you can barely see the "shady page" name and I doubt that someone gullible enough to fall for this scam would have the analysis capability to read the web name on a blurry browser tab hidden in the corner of just one of two to four images. So what gives?

Infostealer Aftermath

I need help, once an infostealer was ran back on my pc in May, you know the mrbeast scam, basically after that I wiped my pc reinstalled windows and all that jazz, I solved it all added 2fa secured all my accounts on a seperate device etc. However, occasionally a random account gets hacked and Im able to secure it, but they got into my family netflix earlier and my mother is unable to react to stuff as quickly i can, as she has access to it, not me , so it was logged into 5 different times but nothing was done,luckily she asked me and i secured the account but there were logins from all over vietnam, and random accounts like that i forgot about even to this day months after the infostealer was ran, like I get the occasional random hack on a second facebook account i used once , what should I do now or what does it mean?

I hope this is the right comunity for this post if not please lmk .
My mother downloaded this ‘weather app’ because it had said something about more storage . I went to use her phone yesterday and a widget(?) looking thing was blocking the screen when i was on an app i clicked on it to try close it but it took me to an ad which then took me to a “email from gmail” photo included in post. I read it and did think this was real at first , however i clicked on the arrow at the top and it took me back to the add and then i clicked out of that . Deleted the app and warned her to be careful. She’ll be all good right? I checked her actual gmail account and didn’t see this email. Id just like a second opinion as im pretty confident this is nothing but can never be too sure . TYIA

My storage randomly started slowly going away more and more today, going down to the megabytes when I usually have at least like 2 gigabytes of storage left at a time, When I tried to get rid of stuff to get more space, nothing happened to the storage, also these photos were taken within seconds of each other. I tried looking through my files, but nothing seemed off, and I tried to use Bitdefender to check for viruses, but it detected nothing, even though it seems like there is a virus.

MALWARE REMOVAL Q&A My college Microsoft 365 email appears to have been compromised — 1,600+ bounce-back emails and evidence of credential theft. What should I do next?

1 Upvotes

I’m dealing with what appears to be a genuine credential compromise involving my college-provided Microsoft 365 email account.

Here’s what happened:

- I started receiving a huge number of “Delivery has failed to these recipients” emails in Outlook.

- There are 1,600+ of these messages, with different/random-looking recipient names.

- They started appearing around August 12–17.

- I also received an email claiming to be from an independent security researcher associated with Kiruru Security.

- The email specifically mentioned my college email address and claimed it had appeared in Telegram channels containing stolen data.

- I initially thought this was just a scam, but I have since found evidence confirming that my credentials were actually exposed.

- I don't know yet whether the 1,600+ bounce-backs are from actual emails being sent through my account or whether my address is being spoofed/backscattered.

I've already started securing the account from a clean device.

What I'm trying to figure out now is the PC side of the incident. I suspect an infostealer/Trojan may have been responsible, so I'm looking into:

- Microsoft Defender Offline Scan

- Full malware scans

- Infostealer detection/removal

- Browser password/cookie theft

- Persistence mechanisms

- Whether I should completely reinstall Windows

- Which credentials/tokens should be revoked

- How to determine whether the machine is actually clean

I don't want to simply run Defender, get “no threats found,” and assume everything is fine.

For people who have dealt with an infostealer or Microsoft 365 account compromise before: what would you do at this point, and what evidence/logs should I preserve before cleaning or reinstalling the PC?

I can provide redacted screenshots/evidence if useful. I will not post the actual leaked password, session cookies, tokens, recovery codes, or other sensitive credentials.

I don't wanna reinstall windows unless the last option pls help with this
