Virus stands for Vital Information Resources Under Seize. A virus is a malicious program or software whose aim is to harm or damage the data. It is a type of malware that can be compared to any biological virus. Just as biological viruses range in severity and type of infection, computer viruses follow a similar trend. It can display annoying pop-up messages computer system. Computer viruses need a host program. As we all know that virus is a code so it writes the code on the host program. When the host program gets executed, the infection starts. Viruses can replicate themselves using the host program. The study of computer viruses can be traced back to 1949 and the first virus was developed in 1971, also known as the ‘Creeper Program’.
