    Computer viruses have a life cycle that begins while they are created and come to an end when they are totally destroyed The following information explains each stage. Until a few years ago, making or you can say coding a virus needed knowledge of a computer programming language. But in today’s world a little programming language is more than enough Generally, though, viruses exist by unwise individuals who desire to cause widespread, casual damage to computers.

    Viruses that have damage routines will make active when a few conditions are satisfied , for instance, on a particular date or when a particular action is performed by the user. Viruses without damage procedures do not trigger, instead causing harm by stealing storage space. Then after the activation the Virus is being discovered , but often this does not happen very early . To prevent your system from a virus you need to keep a copy of updated AntiVirus installed in your system .

    Re: Life cycle of a computer virus

    Boot sector viruses were the most common virus type, scattering principally in the 16-bit DOS world through floppy disk. Boot sector viruses contaminate the boot sector on a floppy disk and multiply to a system’s s hard disk, and can also infect the master boot record (MBR) on a system's hard drive. Once the MBR or boot sector on the hard drive is comes under the impact of the virus , the virus tries to infect the boot sector of each floppy disk that is put into the computer and being used Removing up a boot sector virus can be done by booting the system from an virus free floppy system disk rather than from the hard drive .
