Hey everyone, I need some advice because I'm honestly pretty stressed about this.
I was browsing moviesmod.com when a fake Cloudflare/human verification popped up. It instructed me to press Win + R, paste something using Ctrl + V, and hit Enter. Unfortunately, I followed the instructions without thinking.
Nothing obvious happened immediately, but I got worried and started checking Windows Security.
Here's what happened afterward:
A Quick scan initially showed no threats.
I tried running Microsoft Defender Offline, but my laptop's battery died during the process. After rebooting, I got a BitLocker recovery screen, entered the recovery key, and Windows booted normally.
Later, Windows Defender detected TrojanDropper:PowerShell/Cobacis.B, marked as Severe, with its status showing Quarantined.
A subsequent scan detected PUABundler:Win32/MediaGet, marked as Low and initially showing Active in my Chrome cache. I removed the unwanted item through Windows Security.
I've also enabled potentially unwanted app blocking and run a scan afterward.
I haven't logged into any accounts or entered any passwords since following the fake verification.
My questions are:
Does the quarantined Trojan mean that specific file is contained, or could it have executed other things beforehand?
If the scan has finished and I've removed the unwanted item, is that generally enough, or should I do anything else?
Is there any reason to suspect my personal files or accounts are compromised?
Do I need to complete another Defender Offline scan, or is that unnecessary if everything looks okay?
I'm using Windows 11 with Microsoft Defender. I'm hoping to avoid reinstalling Windows or factory-resetting my laptop unless there's a genuine reason to.
I'd appreciate practical advice from anyone who's dealt with this. Please be honest, but I'd also like to avoid unnecessary panic.
