--> Worm <--

Usually the worms do not need, such as classic viruses, bind to executable files but require user intervention to infect the system.

This barrier, however, is falling for some time because many worms to start self exploit vulnerabilities in the operating system that does not solve the user through the application of appropriate security patches.

Like viruses, worms contain a piece of malicious code (payload) and increasingly trigger a backdoor or a keylogger opening the door to other types of attatto from Network.

--> Trojan <--

The Trojan Horses ono a digital avrsione of stratagem used by Ulysses to enter the city with his soldiers.

The Trojans seem to want information that is not in order to force him to launch a program actually harmful.

This is one more reason for matenere always constantly updated the software used (starting from the operating system).
