In the last years, cybercriminals distribute a new type of viruses that can encrypt files on your computer (or your network) with the purpose of earning easy money from their victims. This type of viruses are called “Ransomware” and they can infect computer systems if the computer’s user doesn’t pay attention when opening attachments or links from unknown senders or sites that have been hacked by cybercriminals. According to my experience, the only safe way to keep yourself protected from this type of viruses is to have clean backups of your files stored in a separate place from your computer. For example, in an unplugged external USB hard drive or in DVD-Rom’s.
This article contains important information of some known encrypting ransomware –crypt- viruses that were designed to encrypt critical files plus the available options & utilities in order to decrypt your encrypted files upon infection.
