Ransomware is a type of malware which denies users from accessing their own computers. Ransomware encrypts all the content in your computer and demands a sum of money in order to grant you access to your system.
What Ransomware does is that it shows you a popup when your computer starts. The popup is usually a fbi – type message which asks you for payment of a certain sum of money in order to unlock and decrypt your files. However there is no guarantee that your files will be decrypted even after you pay them the money.
