What Is Computer Worm, Spyware, Rootkits

Hi Search Freaks

Here i come up with the few other definitions of the terms used in the field of Virus, Antivirus, Hacking.

This is my last post about the brief explanations of the terms used in the world of Virus, Antivirus & Hacking, which I was posting from last few days. Here are fews...

What is Computer Worm :

A Worm is similar to a virus by its design, and is considered to be a sub-class of a virus. Worms spread from computer to computer, but unlike a virus, it has the capability to travel without any help from a person. A worm takes advantage of file or information transport features on your system, which allows it to travel unaided. The biggest danger with a worm is its capability to replicate itself on your system, so rather than your computer sending out a single worm, it could send out hundreds or thousands of copies of itself, creating a huge devastating effect. One example would be for a worm to send a copy of itself to everyone listed in your e-mail address book. Then, the worm replicates and sends itself out to everyone listed in each of the receiver's address book, and the manifest continues on down the line. Due to the copying nature of a worm and its capability to travel across networks the end result in most cases is that the worm consumes too much system memory (or network bandwidth), causing Web servers, network servers and individual computers to stop responding. In more recent worm attacks such as the much-talked-about .Blaster Worm., the worm has been designed to tunnel into your system and allow malicious users to control your computer remotely.

What is Computer Spyware :

Spyware is software installed on a computer that is designed to collect information about the computer user, often without their knowledge or consent. This can result in so called identity theft, or theft of valuable information (e.g. bank or credit card details) or proprietary business data. Spyware is often developed by organized crime rings rather than lone individuals and may be installed by a virus.

What is Computer Rootkits :

Rootkits are programs that install on your computer while keeping themselves and their activities hidden to remain invisible to theuse. They represent a significant security risk on both home computers and company networks and are notoriously difficult to find and remove. Rootkits themselves are normally installed by a virus or other type of malware infection and it is therefore highly recommended that computer users have up to date antvirus / anti-spyware software installed and running on their computer

So friends now this is the end of my brief writing about the terms used in the world of viruses, antivirus, hacking, which I was writing from last few days ……. So friends enjoy the life; because “Life Is Like That”.
