To create a virus, a user or attacker needs to create a code. In this code the attacker needs to express what type of virus, he/ or she wants to use. Once the attacker determines what type of virus is going to be used, then they must determine who they want to attack. Lastly, ask what type of data they want to gain from the attack. People write computer viruses. The person has to write the code, test it to make sure it spreads properly and then release it. A person also designs the virus's attack phase, whether it's a silly message or the destruction of a hard disk. .
There are at least four reasons why this is done. The first is the same psychology that drives vandals and arsonists. For ...view middle of the document...
Destroying everything on a person's hard disk is real damage. Forcing a large company to waste thousands of hours cleaning up after a virus attack is real damage. Even a silly message is real damage because someone has to waste time getting rid of it. For this reason, the legal system continues to develop more rigorous penalties for people who create viruses.
Computer viruses are called viruses because they share some of the traits of biological viruses. A computer virus passes from computer to computer like a biological virus passes from person to person.
Unlike a cell, a virus has no way to reproduce by itself. Instead, a biological virus must inject its DNA into a cell. The viral DNA then uses the cell's existing machinery to reproduce itself. In some cases, the cell fills with new viral particles until it bursts, releasing the virus. In other cases, the new virus particles bud off the cell one at a time, and the cell remains alive.
Similar to the way a biological virus must hitch a ride on a cell, a computer virus must piggyback on top of some other program or document in order to launch. Once a computer virus is running, it can infect other programs or documents. The is the analogy between computer and biological viruses.
It is important that antivirus software needs to be update. Types of Viruses: boot sector – sits in the boot sector of hard drive, begins as soon as the machine is booted up. Both MAC and windows can be infected. Program viruses – the virus is embedded into an application, and whenever that application is started the virus spreads. Script Virus – not commonly seen, but is normally found in the java script. Marco virus – commonly affected Microsoft Office, and once any program was ran, the virus attacked the operating systems.
Worms is also a type of malware and replicates itself, as long as your computer is...
