Detailed explanation-1: -A computer virus is a piece of code embedded in a legitimate program and is created with the ability to self-replicate infecting other programs on a computer. Just like how humans catch a cold or flu, it can remain dormant inside the system and gets activated when you least expect it.

Detailed explanation-2: -Think of it like the common cold, often a computer virus can simply slow down your device, whereas like the flu, things can become more serious and your device may stop operating altogether. Much like the common cold or the flu virus, a computer virus can also replicate itself and spread from one device to another.

Detailed explanation-3: -A computer virus is malicious code that replicates by copying itself to another program, computer boot sector or document and changes how a computer works. A virus spreads between systems after some type of human intervention.

Detailed explanation-4: -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-5: -While biological and computer viruses have similarities, there are, of course, significant differences in how they behave and how they can be tackled. It’s important to remember that humans come with a built-in, self-enhancing “antivirus, ” but most devices don’t.
