: Double-clicking the file can execute malicious code that may steal your passwords, encrypt your data (ransomware), or install a backdoor.
: A genuine high-quality video file is usually large (hundreds of MBs). If the file is very small (under 5 MB), it is likely a script or executable.
: Run a full system scan using a reputable antivirus or anti-malware program (like Microsoft Defender or Malwarebytes) to ensure no secondary infections occurred. 3. Verification (If you must check)
: Only inspect such files within a secure, isolated virtual machine (Sandbox) that is not connected to your personal data or network. 4. Prevention Tips
: Never download files from unsolicited messages or pop-up ads promising "exclusive" content.
