A network system is not only comprised of computers but also includes supporting equipment such as firewalls, switches, printers, scanners, handled assets such as CDs and DVDs, printers, wi-fi hot spots and not to forget security cameras. Worms are different from the standard computers and their drivers that run on the platform. Worms are the computer code, complete with all the programming and self-replicating ability which gives it the capability to virtually spread to every computer in a network. Worms may be present in secret compartments of a computer.
Some worms can replicate themselves
Worms, by definition, seek to replicate themselves from inside vulnerable systems and electronically transmitting their messages from a multicast loop to vulnerable systems in the form of data. Worms are small pieces of computer code designed to travel from one system to another through networks, infecting one or more target systems along the way. Because of self-replicating ability, a worm can plug and play, usually having no user interaction. Because of the capability to plug and play, a worm can multiple computers to a network and perform different functions without human intervention.
This ability makes them both viruses and Trojans. The difference between a computer worm and a computer virus is that a Trojan virus can perform certain tasks on multiple systems, whereas a computer worm can perform different tasks on multiple computers at once. A Trojan virus may spread by being sent to e-mails. Worms may be spread through the network. Because of their supporting abilities, viruses have high APFR importance, which indicates that they are capable of damaging other programs and files, corrupting data, and system software. It is therefore important to have a top-quality antivirus program to combat these computer worms.
Aside from viruses, a computer worm may also spread to and from other computers attached to the network. These worms can also spread to and from hand-held and other devices such as digital photo cameras and MP3 players. Some worms are even specific to certain types of operating systems, such as Windows operating systems and Apple operating systems.
Uses of Computer Worms
vicious computer worms are created to cause damage to a computer and allow unauthorized users or software to access the computer or data. Some worms even act as decoys, i.e. they act like a virus, but don’t require file Association for activation, thus allowing them to bypass antivirus protection. Many different computer worms such as Spread To Endpoint worms, E-mail worms (also called Email Virus aiding to send malicious attachments), and W32 (Win32). Worm made use of features such as loopholes, which allow them to spread automatically to all the computers in a network by automatically attaching itself to existing files on the computer.
How to Save a Computer From Hacking? As seen in the previous section, a computer worm is already capable of copying data from the infected computer to a remote computer. Some worms let the users download a self-extracting executable file from the infected computer. However, by using this function, a user can get an executable file that may require regaining control after double-clicking. This is one way of how to save a computer from hacking.
Antivirus software and conventional anti-virus software can protect a computer. However, there is much more one can do to protect a computer from hacking. Well, with the advancement in technology, the anti-virus software is taking far more sophisticated measures to protect a computer from hacking, and also to study the Techniques of how to attack the networks, how to stop the virus, and prevent the computer from becoming infected with the Virus.
There are three types of Anti-virus software:
- Antivirus Software
- Anti-ware software
- Botnet software
Antivirus software is far more complex as compared to anti-ware software to provide greater protection to a computer. Some anti-virus applications scan a computer in real-time as it works on gathering evidence of a virus attack in real-time.
Modern anti-virus software is capable of filtering internet content and blocking e-mails from correspondents. It remains in the memory of all the software that may be working at some remote corner of the globe. The new generation of anti-virus software has a sophisticated System protection module, which may notify the System Support if there is any threat from any outside source.
Botnet software and other malicious software are eliminated by the anti-virus software. They are specially designed to volk the security holes in the computer systems.
