Malware is a general term used to describe any malicious software, including viruses, trojans, spyware, adware, etc.
Here are some examples of malware:

Spyware - a type of malware that collects information about the user without their knowledge or consent.
Adware - a type of malware that displays unwanted ads on the user's device.

These are just a few examples of the many types of malware that exist. The threats posed by different types of malware can vary greatly, and it's important to stay informed and protect your devices and networks against these types of attacks.
Ransomware, on the other hand, is a type of malware that encrypts a victim's files and demands a ransom payment to restore access to the files. The key difference between malware and ransomware is that malware is a broader category that encompasses many types of malicious software, while ransomware specifically refers to a type of malware that holds the victim's data hostage in exchange for payment.
Here are some examples of ransomware:
WannaCry - a ransomware attack that spread rapidly across the globe in 2017 and affected hundreds of thousands of computers.
Petya - a ransomware attack that first emerged in 2016 and used malicious software to encrypt victims' files and demand a ransom payment.
Locky - a type of ransomware that encrypted victims' files and demanded payment in the form of the virtual currency, Bitcoin.
Cryptolocker - a type of ransomware that encrypted victims' files and demanded a ransom payment to restore access.
Ryuk - a type of ransomware that is known to target large organizations and government agencies.
These are just a few examples of the many types of ransomware that exist. Ransomware attacks can cause significant financial losses and disruption, and it's important to take steps to protect against these threats. This can include maintaining regular backups of important data, keeping software up-to-date, and using strong passwords and anti-virus software.
