If you do not know the sender of an e-mail do not open the attached file or do not click the link inside the body of the mail.
Such attack is called “ransomware”, because once our data has been encrypted, it can only be used with a key.
This latter is only in the possession of the pirate who initiated the attack, he will only give it against a ransom (ransomware).
Due to the variability and diversity of attacks we are not able to technically intercept all despite our current security measures.
If it is too late, you have to disconnect your PC from the network (LAN cable / WiFi) or switch off the PC and contact the IT department.
