Disconnect your computer from the network or the internet to prevent further spread of the ransomware. Report the incident to your organization's IT department or contact a professional cybersecurity service for assistance. Do not pay the ransom. There is no guarantee that the attacker will provide the decryption key, and paying encourages further criminal activity. If you have backups of your data, restore your files from a clean backup source after removing the ransomware from your system. Strengthen your security measures by updating your software, implementing stronger passwords, and enhancing your overall cybersecurity practices to prevent future attacks.
