How did ransomware infect my computer?

Cybercriminals use various methods to spread threats like D0nut Ransomware. Spam emails are one of the most used and effective ways of distributing malware. They carry malicious attachments and links that instantly trigger the download of infection on opening.  Apart from that, bundled freeware programs, peer-to-peer (P2P) file-sharing networks, cracked software, and fake updates are also used.
