Worm or Virus…What’s the Difference?
Everyone has been infected with a virus at one time or another either through the common cold or the flu. A virus attacks the human body by entering through one of the many openings and attaching itself to a host cell. It releases a piece of genetic information into the cell and recruits the cell’s enzymes to propagate the genetic information. Once the genetic code has been adequately replicated, it destroys the cell and attacks cells nearby.How does a computer virus simulate a biological virus? Just as a biological virus injects its own genetic information into a cell and interferes with the body’s normal operations, a computer virus is a program written to interfere with the proper functioning of a computer. It may damage programs, delete files, reformat hard disks and perform other forms of destructive acts.
What is exactly a computer virus?
” A program that can infect other programs by modifying them to include
a slighty altered copy of itself.A virus can spread throughout a computer
system or network using the authorization of every user using it to
infect their programs. Every programs that gets infected can also act as
a virus that infection grows “
