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:

We all know that many viruses or worms or spam continuing and repeatedly booming the internet network. For us who already know their existing, installing anti virus or anti spam system is the primary solutions.
Although how powerful your anti virus system is, but if you do something such as letting those spam in, it means your data is in high risks. So how to solve the problems? lets find out below.

Another malware we would like to discuss are hybrids, droppers, and blended threats. The common making of software also generate ease of creating hybrid malware as well.
A classic hybrid example was presented by Ken Thompson in his ACM Turing award lecture. He prepared a special C compiler executable which, besides compiling C code, had two additional features: Read the rest of this entry »
Malware can be roughly broken down into types according to the malware’s method of operation. Anti-”virus” software, despite its name, is able to detect all of these types of malware.
There are three characteristics associated with these malware types.
1 Self-replicating malware actively attempts to propagate by creating new copies, or instances, of itself. Malware may also be propagated passively, by a user copying it accidentally, for example, but this isn’t self-replication.

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.

A reverse firewall filters outgoing traffic from a network, unlike a normal firewall which filters incoming traffic. In practice, filtering in both directions would probably be handled by the same software or device.
As with firewalls, the key to an effective reverse firewall is its policy: what outbound connections should be permitted? The principle is that a worm’s connections to infect other machines will not conform to the reverse firewall policy, and the worm’s spread is thus blocked. The decision is based on the same packet header information as was used for a firewall, including source and destination IP addresses and ports.

In the world that change quickly, its important to gain and increasing your knowledge. This is also applied in computer knowledge, think outside of the box is way to do it.
Remember the big names such as Steve Jobs and Bill Gates, they start it from zero, Mark Zuckerberg (facebook) and Larry Page and Sergey Brin (google inc.) comes with existing concept that already there, but renew and more better.
