Ransomware is malware that will prevent you from accessing your computer by blocking access to your system or encrypting your files. To regain access to your files, apps or computer, this type of malware will ask you to pay a ransom or will pretend that it acts on behalf of law enforcement and demand payment of a fine. Legitimate law enforcement will never use these tactics. If you think you are infected by this type of malware, run a trusted security and antivirus software and seek help from an expert.
It’s important to keep in mind that even if you answer all requests, it’s possible that you will never regain access to your files, apps or system without formatting your entire machine.
