Malicious software includes worms, the classic network viruses, Trojans, hacking tools and other software, causing deliberate harm to a computer on which they are executed, or to other computers on the network.

Network Worms.

This category includes programs that spread its copies to local and / or global networks in order to:

? Penetration of remote computers;

? The launch of its copies on the remote computer;

? Further spread to other computers on the network.

In order to spread worms use a variety of computer and mobile networks: electronic mail, instant messaging, file sharing (P2P) and IRC-network, LAN, network data exchange between mobile devices (phones, PDAs), etc.

Most of the known worm spreads in the form of files: the attachment in an email, a link to an infected file on any web or FTP-share in the ICQ-IRC-and communications, file in the exchange of P2P, etc.

Some worms (“packet” worms) are distributed in the form of network packets to penetrate directly into the computer memory and activate their code.

To penetrate the remote computers and the launch of its copies the worms use different techniques: social engineering (eg, text, e-mail, calling to open the attached file), failures in the network configuration (eg, copy to disk, open for full access), errors in the security services of operating systems and applications.

Some worms also possess the properties of other types of malicious software. For example, some worms, Trojan horses contain a function or can infect executable files on local disk, i.e., they have the property of the Trojan program and / or computer virus or other malware.

Classic usual viruses.

This category includes programs that spread its copies to resources on the local computer for:

? Follow up your package at any action of the user;

? Further implementation in other computer resources.

A copy of this virus damages the remote computer if the object is started on other PC, for example:

? Infection of available drives – virus penetrated the files located on a network resource;

? The virus copied itself to removable media or infected files on it;

? User sent an email with an infected attachment.

Some viruses contain the properties of other types of malicious software, such as a backdoor procedure or Trojan component of destroying data on disk.

Trojan programs.

This category includes programs performing various unauthorized actions of the user: information gathering and transferring it to an attacker, its destruction or malicious modification, any malfunction of the computer, the use of computer resources in the wrong purposes.

Certain categories of Trojans cause damage to the remote computers and networks, not affecting adversely the ability of the infected computer (e.g., Trojans, designed for massive DoS-attacks on remote network resources).
