🛑 Can PDF, MP3 & other files contain viruses? YES!

Here’s how 👇

📄 PDF Files
PDFs can contain JavaScript like this:

app.alert("You are infected!"); 

⚠️ They may:

• Run scripts automatically
• Redirect to phishing sites
• Contain hidden EXE/BAT files

🎵 MP3 Files
MP3s are audio, but still risky!
Example: song.mp3.exe
If file extensions are hidden, it looks safe — but it's actually a virus.
Some media players also have bugs that can be exploited via corrupted tags.

🧾 Other risky file types:
• .docm, .xlsm → Macros (malicious code)
• .zip, .rar → Hidden payloads
• .scr, .bat, .cmd → Scripts

🔐 Stay safe:

✅ Show full file extensions
✅ Don’t open unknown attachments
✅ Keep antivirus up to date
✅ Disable JavaScript in PDF readers
✅ Avoid double extensions


💡 Even files that “look normal” can be deadly.
