If our computer system attacked by virus, it will be able to damage the operating system and causing the loss of our data or even destroyed our whole computer system. While a worm is a program which is able to duplicate itself and it is repeatedly. The repeatedly duplicated files use up the available space and slow down a computer operating speed.
