WannaCry is a type of ransomware that is evolving as an extremely heinous malware. Once, your system becomes a victim of this attack, the ransomware locks up your system, encrypts the files and then demands a ransom (in Bitcoin) from the owner to get back the access. Most ransomware gets into your system if you download Word documents, PDFs and other files sent via unsolicited emails unknowingly. These also spread through computers that are already affected or are victims of malware that offer backdoor for other malware or viruses. The best way to get complete protection against ransomware is to download and use a strong antivirus or anti-ransomware software with powerful ransomware removal tools.
