There were about 57,000 computers in 99 countries that were infected with a ransomware worm called "WannyCry" reports Aljazeera.
What the WannyCry ransomware does to your computer once it infected is encrypt or lock up your files on your computer that you won't be able to access them anymore.
For you to recover your files, you need to pay the hackers money in terms of bitcoin for you to receive a key use to decrypt your files.
Software security companies said that when your computer system is infected, "a pop-up window will appear with instructions on how to pay a ransom amount of $300." Ransomware victim will be given a deadline to pay the ransom, if not, all data will be lost.
