Among the malicious code, three large families are dominant threats: viruses, worms and Trojans. By definition, the purpose of a computer virus is contagious, like a real virus. It uses so many processes that have evolved over time to facilitate its spread. Originally, the first virus is conveyed via removable storage disk in a second stage disks, then CD.

With the spread of Internet viruses networks have multiplied and now constitute the main transmission route chosen by their authors. For these network viruses, experts talk about them. A worm is based primarily on flaws in the browser or operating system to settle and contaminate all positions of a network (LAN or internet). Email worms based on their share on the mail relay to spread.

Finally, the Trojans are viruses disguised as ordinary applications to cheate the security of the user. A Trojan horse usually mimics the name of the application but also its installation process, its logo and goes to confirm the user installing the application. When present on the job, the Trojan leaves entering the system that a hacker could exploit to gain access.

Most hackers are not intent on destroying your system. they just want to use your system for storage of malicious things. they usually use a trojan becuase it allows them access to go back to your system and view their stored information on your system.
