Ransomware is a class of malware that can encompass any of the above vectors in order to be executed on a system, though ransomware is often deployed as a Trojan. Spyware: Spyware applications are malicious programs that spy on a user’s actions, and can record private data and send it to a remote server.To that end, Trojans are often voluntarily downloaded and executed by victims due to the seemingly innocuous nature of the application. Trojan: A Trojan is a program that appears harmless, but in the background operates in a malicious manner, such as by recording keystrokes (keylogger), setting up a proxy and sending data to a remote server, or encrypting files forcefully (i.e.Essentially, a worm can operate as a self-propagating, self-executing program that can remain undetected for some time, while it carries out its malicious activities.

Worm: A worm is one of the most powerful and malicious forms of malware in that worms do not require human actions to spread or execute.Virus: A virus is a malicious program or application that is deployed onto a system - typically spreading via a network or email-related social engineering attacks - requiring a user to both spread and execute in order for the malicious activity to be accomplished.Typically, malware is divided into four categories: Malware (malicious software) is classified as a software-based threat (program) that is deployed as a payload against a system that contains a vulnerability. While the occurrence of malicious data breaches has increased, and different forms of both active and passive security attack vectors and zero-days are on the rise, one of the most damaging and increasingly significant forms of malware is ransomware. In an age of increasing cybersecurity threats, it is of the utmost importance for SMEs - as well as large companies - to be fully aware of all Information Technology (IT) cyber-threats that may result in a costly data breach.
