1. Uninstall the Suspicious App:

    • Go to your device's settings.
    • Find the list of installed apps.
    • Locate FMWhatsApp and uninstall it.
  2. Scan Your Device for Malware:

    • Install a reputable antivirus or anti-malware app from a trusted source (such as from the Google Play Store if you're on Android).
    • Run a full system scan to detect and remove any malware on your device.
  3. Change Your Passwords:

    • Change your passwords for your email accounts, social media accounts, and any other sensitive accounts. This is a precaution in case any of your login credentials were compromised.
  4. Check for Unauthorized Activity:

    • Review your accounts for any unauthorized or suspicious activity, such as unusual logins or changes to your account settings.
  5. Update Your Apps and OS:

    • Make sure your device's operating system and all other apps are up to date. This can help patch any security vulnerabilities.
  6. Install a Trusted Version of WhatsApp:

    • If you want to continue using a WhatsApp mod, download one from a reputable source and verify its legitimacy to avoid malware.
  7. Use Official Apps:

    • It's recommended to use the official WhatsApp application from the Google Play Store or Apple App Store to ensure your security and privacy.
  8. Report the Incident:

    • If you suspect that the malicious FMWhatsApp update is widespread, consider reporting the incident to the platform where you downloaded it and, if necessary, to law enforcement.
  9. Be Cautious in the Future:

    • Avoid downloading apps or updates from unverified sources or sources outside official app stores.
  10. Backup and Restore Data:

  • If you have backed up your data, you can restore your chats and information to the official WhatsApp application after ensuring your device is secure.

Remember that using unofficial WhatsApp mods can be risky, as they may not undergo the same security checks and oversight as official apps. It's generally recommended to stick with the official WhatsApp application to ensure the security and privacy of your communications.
