An unwanted program running on a computer is called
a: Pain
b: Sickness
c: Encryption
D: Virus
Answer: D: Virus
A virus is a surveillance software (malware), specially created to replicate and infect computer networks, frequently endangering consistency or carrying out bad deeds. The problem is that any computer that catches a virus is capable of copying itself and infecting other machines including the other on the network without the user’s expression of will or control.
Viruses have different injurious consequences, for instance, virus may destroy or damage files, take secret materials, reduce performance or completely take control of the experimented computer. They can move through a wide range of ways: emails with infected attachments, false websites or USB replicated storages.
Through the concepts “pain”, “sickness”, and encryption”, the user is supposed to be inflicted to refer to the unidentified programs running on computer. ‘Virus’ is actually a scientific term employed to denote a harmful program, which is self-replicating in nature and capable of invading and infecting computer systems.
