Ransomware has grown to be one of the biggest issues on the web. Its a malware which upon being launched, encrypts files on a PC or on the network.These encrypted data will be recovered (decrypted) only when a ransom is paid to the perpetrator in the form of bitcoins. However there are cases where data is never decrypted even when the ransom was paid. A ransomware infection often starts when a user clicks a malicious attachment, malicious email ink or if the user visits a compromised website.
