A virus hoax is essentially the same as a chain letter, but contains “information” about some fictitious piece of malware. A virus hoax doesn’t do damage itself, but consumes resources – human and computer – as the hoax gets propagated. Some hoaxes may do damage through humans, advising a user to make modifications to their system which could damage it, or render it vulnerable to a later attack.

There are three parts to a typical hoax email:
1. The hook.
This is something that grabs the hoax recipient’s attention.

There are several methods in detecting viruses, is it already infecting your computer or not. Today, lets discuss the first method, which is detecting through behavior monitors or blockers.
A behavior blocker is anti-virus software which monitors a running program’s behavior in real time, watching for suspicious activity. If such activity is seen, the behavior blocker can prevent the suspect operations from succeeding, can terminate the program, or can ask the user for the appropriate action to perform. Behavior blockers are sometimes called behavior monitors, but the latter term implies (rightly or wrongly) that no action is taken, and the burglars are only watched while they steal the silver. Products cables for the sound system. Cheap audio cables.

With the exception of companion viruses, viruses operate by changing files. An integrity checker exploits this behavior to find viruses, by watching for unauthorized changes to files.
Integrity checkers must start with a perfectly clean, 100% virus-free system, it is impossible to understate this. The integrity checker initially computes and stores a checksum for each file in the system it’s watching. Later, a file’s checksum is recomputed and compared against the original, stored checksum. If the checksums are different, then a change to the file occured.

Anti-virus software can employ static heuristics in an attempt to duplicate expert anti-virus analysis. Static heuristics can find known or unknown viruses by looking for pieces of code that are generally “virus-like,” instead of scanning for specific virus signatures.
This is a static analysis technique, meaning that the code being analyzed is not running, and there is no guarantee that any
suspicious code found would ever be executed. Static heuristic analysis is done is two steps:

Since computer technology were introduced, the other related supportive tools are also improving. One of it is Network, with network we could travel the world less then a second, there are no limit to far and no obstacle to hard.
Network itself rely on connection quality, which the first and still being used until now is cable. Cable itself also being used for common electric peripherals.

In computer world, performance is something needed in order to get the job done more quickly, while precaution is something we need to do to avoid unwanted files.
Scanning an entire file for viruses is slow, and resulting on the computer performance itself. So how to solve it, because we do know scanning is also important things to do. It is referred to using the derogative term grunt scanning. There are four general approaches to improving scanner performance:

In previous articles we have discuss about browser battle, thus the battle are effecting on web design. Those browser development are potentially effecting on web design in both positive and negative side.
The browser war results in newer, better features that you can implement on your Web sites. The blistering pace of development leads to regular updates and bug fixes in browsers, as well as timely changes in the user interface, brought about by consumer comments. If you’ve spent much time surfing the Web, you’ve probably seen excellent uses for advanced HTML capabilities, such as tables, frames, and forms. The features allow users to view information in columns or cells, navigate sites using toolbars, and give and receive feedback.
