Malicious Code

Malicious Code
Malicious code is generally described as a file or type of software that interferes with the normal function of an operating system. It can be used to compromise a computer to participate in zombie attacks, steal sensitive information or install other types of malware. Common malicious code classification Virus - a program or file that can attach itself to other programs when executed. Worm - a program or file that replicates itself into the nodes of a network. Unlike a virus, a worm does not rely on host files to carry the infection. Trojan - a program that portrays itself as a genuine program. While they appear legitimate, Trojans have another agenda, usually one of malicious intent. Unlike worms and viruses, a Trojan is the type of malicious code that doesn’t replicate. In many cases, the most common elements of malicious code have been combined to inflict considerable damage. For instance, a user may unknowingly install a Trojan by clicking on a tempting image. The Trojan can then download a virus which can leave the system vulnerable to worms and other security threats.
