Detailed explanation-1: -Definition: A computer virus is a malicious software program loaded onto a user’s computer without the user’s knowledge and performs malicious actions. Description: The term ‘computer virus’ was first formally defined by Fred Cohen in 1983. Computer viruses never occur naturally. They are always induced by people.
Detailed explanation-2: -Spyware is a type of malicious software–or malware–that is installed on a computing device without the end user’s knowledge.
Detailed explanation-3: -A virus, on the other hand, is a type of malware. Its definition is limited only to programs or code that self-replicates or copies itself in order to spread to other devices or areas of the network. Based on the above definitions, the word malware can be used to refer to any type of virus.
Detailed explanation-4: -A computer virus is a type of malware that attaches to another program (like a document), which can replicate and spread after a person first runs it on their system. For instance, you could receive an email with a malicious attachment, open the file unknowingly, and then the computer virus runs on your computer.
