A computer system virus is a kind of malicious code or program that, when executed, reproduces itself by customizing other computer system programs and placing its own code. When this replication is successful, the affected areas are then stated to be infected with a virus. citation Viruses typically spread by producing a copy of themselves on a user's computer system without the user's knowledge or approval. Oftentimes, infections will be spread by email accessories or by files shared on peer-to-peer networks. When a virus has infected a computer, it can spread to other computers on the very same network. Some viruses are set to spread themselves in such a way that could cause major damage to a computer system. A virus may delete files, fill a tough drive with ineffective information, or corrupt system files. In some cases, a virus might even show a message or image that is designed to scare the user. A lot of viruses are relatively harmless, and only trigger small inconvenience to the user. However, some infections can be really unsafe, and can trigger widespread damage to computer system systems.A bug is a sort of harmful code or program that, when implemented, duplicates by inserting itself right into various other computer system programs, data files, or the boot industry of the hard drive. Because of this, virus can spread throughout a network of computers and cause significant damages.
