Set your computer to "Show file extensions" so you can see if a "Document" is actually a dangerous .exe file.
You can upload suspicious files or paste the MEGA link into VirusTotal to see if dozens of different antivirus engines flag it as a threat.
⚠️ , I recommend immediately disconnecting your computer from the internet and changing your passwords from a different, clean device. If you'd like, let me know:
Scammers use vague names like "Downloads 462" to spark curiosity or bypass automated filters.
While MEGA is a legitimate service, its end-to-end encryption makes it a favorite for hosting illegal content and malware because the platform cannot easily scan the files.
Where did you ? (Email, Discord, a specific website?) Have you already clicked on anything inside the folder? Are you seeing any strange behavior on your computer now?
