While the intentions of those who write and release worms are difficult to report without a representative sampling, much can be gathered based on the capabilities of the worms they create. These intentions are important to study because they help reveal the likely futures of worms and how much of a defense investment one should make against them.
There appear to be three overriding purposes to worms in their early incarnations. Some worms, such as the Morris worm, seem to have an element of curiosity in them, suggesting that the authors developed and released their worms simply to “watch them go.” Other worms, like the HI.COM worm, appear to have an element of mischievous fun to them because it spread a joke from “Father Christmas.”

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.

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:

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.

If your website sells products or service, you more than likely already know what website shopping cart software is. And if you do not, here is a brief overview explaining it all. Consider the following points.
1. For more of technical people, shopping cart software is a set of scripting instructions that monitors and records each item that a user selects to buy until he/she checks out. In simpler terms, it helps users shop on a website with convenience. Read the rest of this entry »
People want to see what they buy, try before they buy instead of taking your word for it and know where to turn to if something goes wrong. These are some of the things you should consider when thinking of how to sell software online and how to present it.
The list below offers tips on what you should do:
• Have real users test your software product. You may think you have created an easy-to-use intuitive piece of software, yet in the end it is not you who decides this. If you plan on selling software online successfully, you need to have real people test it to see how quick they understand how it works and learn how to use it. Not to mention their help in squashing the bugs you might have never noticed on your own, thus making your product as error free as possible.
