If you did not intentionally download this specific file from a trusted source, you should treat it as high-risk.
: A common tactic is to name a file video.mp4.exe . If your system hides known file extensions, it will look like a safe video file but is actually an executable virus.
: Ensure your operating system is set to "Show file extensions" to confirm it is a true .mp4 and not a .exe or .scr file.
: Use a dedicated tool like the NordVPN File Checker or VirusTotal to scan the file for malicious patterns.
