Overview of Ransomware
WannaCry is still one of the biggest ransomware that has infected more than 200,000 PCs in 150 countries. It spreeds in the form of email, program trojans, and web pages, and has the ability to infect, encrypt and delete files on the attacked computers.
If unfortunately, your files have been encrypted by ransomware, you may be asked to pay the ransom, please don't do so. Since it is not the only option, there are 4 methods that you can try to recover ransomware encrypted files.
How to recover Ransomware encrypted files
