1A-21 14 November 2015 Computer Security: Worms and viruses Nowadays, in the domain of computer sciences, there is a big problem to face: Worms and viruses. Being in the technology is a good thing, but being n the technology without knowing how to avoid the consequences of the technology is worse. Viruses and worms affect the computer and damage, or in other words corrupt some files that are important to the good functioning of the computer. Viruses have many ways of penetration that computers
