Detailed explanation-1: -Malignant computer programs are often called viruses because they share some of the traits of biological viruses. The computer virus requires a functioning “host machine” to replicate, works only with the proper “host, ” and passes from computer to computer like a biological virus passes from person to person.
Detailed explanation-2: -A computer virus passes from computer to computer like a biological virus passes from person to person. Both types of viruses are nothing without their host. Their hosts are their means to both increase their numbers and spreading to other hosts. Both viruses decrease the performance of their hosts.
Detailed explanation-3: -Viruses replicate by creating their own files on an infected system, attaching themselves to a legitimate program, infecting a computer’s boot process or infecting user documents. The virus requires someone to knowingly or unknowingly spread the infection.
Detailed explanation-4: -A computer virus works in much the same way: A computer virus requires a host program. A computer virus requires user action to transmit from one system to another. A computer virus attaches bits of its own malicious code to other files or replaces files outright with copies of itself.
