Explanation:

Spamming is when one person or company sends an unwanted email to another person. Spam emails are the computer version of unwanted "junk mail" that arrives in a mailbox, such as advertising pamphlets and brochures. Spam emails are usually sent to try to get the person to buy something or do something else that will cause gain for the sender.
A Trojan horse, often shortened to Trojan, is a type of malware designed to provide unauthorized, remote access to a user’s computer. Trojan horses do not have the ability to replicate themselves like viruses; however, they can lead to viruses being installed on a machine since they allow the computer to be controlled by the Trojan creator. The term gets its name from the Greek story of the Trojan War, when the Greeks offered the Trojans a peace offering in the form of a large wooden horse.
Phishing is the attempt to obtain sensitive information such as usernames, passwords, and credit card details (and, indirectly, money), often for malicious reasons, by disguising as a trustworthy entity in an electronic communication. The word is a neologism created as a homophone of fishing due to the similarity of using a bait in an attempt to catch a victim.
Phishing is typically carried out by email spoofing or instant messaging, and it often directs users to enter personal information at a fake website, the look and feel of which are almost identical to the legitimate one. Communications purporting to be from social web sites, auction sites, banks, online payment processors or IT administrators are often used to lure victims. Phishing emails may contain links to websites that are infected with malware.
Ransomware is a type of malware that prevents or limits users from accessing their system, either by locking the system's screen or by locking the users' files unless a ransom is paid. More modern ransomware families, collectively categorized as crypto-ransomware, encrypt certain file types on infected systems and forces users to pay the ransom through certain online payment methods to get a decrypt key.
