How to remove and decrypt files from a ransomware virus?

1. Isolate Infected Computer: Disconnect the infected computer from any network or external drives to prevent the ransomware from spreading.

2. Identify the Type of Ransomware: Determine the specific ransomware variant affecting your system. This information can help in finding specific decryption tools if available.

3. Backup Encrypted Files: Make a copy of the encrypted files as they are. Do not modify or delete them in case decryption becomes possible in the future.

4. Check for Decryptor Tools: Some ransomware variants have decryption tools available from security firms or law enforcement agencies. Look for these tools online.

5. Run Antivirus Software: Use reputable antivirus software to scan and remove the ransomware from your system.

6. Restore from Backup: If you have a clean backup of your files, restore your system from that backup after ensuring the ransomware is completely removed.

7. Consult Security Experts: If you are unable to decrypt the files or remove the ransomware, consider seeking help from cybersecurity professionals or reputable tech support services.

8. Update Security Software and Educate Users: Ensure your antivirus software and security protocols are up-to-date to prevent future ransomware attacks. Educate users about phishing emails and safe internet practices.

In case of severe ransomware attacks or if you are unable to decrypt the files, it is recommended to seek assistance from a professional cybersecurity expert.
