Some worms are made for criminal purposes. Lots of these parasites are designed to collect valuable user information like passwords, bank account details, credit card numbers, or identity data, and silently transfer it to the attacker. The remote attacker can use these pests to gain unauthorized access to a compromised computer, steal user's sensitive information or totally destroy the entire system and all user data.ДЄs you can see, aВ worm by itself means a significant risk to your privacy and security. Some parasites can infect a computer with the most serious security and privacy threats, such as various backdoors or trojans. Most of worms can also decrease the system's security by modifying security-related application settings and disabling antivirus or anti-spyware protection. Moreover, the computer becomes the source of viruses and can pose a serious danger to other hosts and networks. The infected PC user can also suffer from web surfing problems, system instability, and softwareВ functionality issues. The infiltration of a worm noticeably decreases overall computer performance and degrades the speed of the Internet.

However, today they can also affect Mac OS X and other systems. Worms have been capable of infectingВ only those computers that run Microsoft Windows operating system. Once the user opens a file, the worm silently infects a computer. Such worms spread the infection in files with meaningful names in order to trick the user into executing them.

Many worms distribute themselves in infected files that arrive attached to instant messages or can be downloaded from file-sharing networks or unprotected network shares.Such parasites spread on their own and therefore do not require any user interference.

#HOW DOES WORM VIRUS WORK SOFTWARE#

Widely spread worms infect vulnerable computers on the Internet by exploiting the known operating system and installed software security vulnerabilities.

The user cannot notice anything suspicious, as a parasite does not display any setup wizards, dialogs, or warnings. Once the user opens such a letter or file the worm silently installs itself to the system. They arrive in files attached to e-mail messages or come embedded into letters.

Some parasites, called mass-mailing worms, propagate themselves through e-mail messages.

There are three major ways these unsolicited parasites can get into the system. Worms replicate themselves and infect a computer without the user's knowledge and consent. How do wormsВ spread and promote themselves? Worms are very similar to regular computer viruses and, therefore, canВ rely on differentВ functionality.

#HOW DOES WORM VIRUS WORK INSTALL#

Most worms can infect files, degrade the overall system's performance and try toВ steal sensitive user's information or install other dangerous parasites, such as backdoors or trojans, on it. Widely spread complex parasites usually propagate themselves by exploiting certain security vulnerabilities in the targeted remote system. A typical worm spreads via e-mail messages, file sharing networks, or through open network shares.

A worm is a malicious self-replicating computer program designed to infect computers in an attempt to deliver a destructive payload.
