Controlling Virus Infections In Internet And Web Servers A Triz Based Analysis, Umakant Mishra

Umakant Mishra

The viruses not only infect the stand-alone machines or client machines but also infect the web servers. When the web servers are infected with viruses, they disseminate infected content and thereby infect the client computers. The conventional anti-virus programs can run only on one machine. There is no way that an anti-virus in the client machine can determine whether the content of a website is virus safe or not. Hence, different methods are implemented to prevent the client computer from being infected by the infected content of a web server.

One proposed efficient method is to get scanned by the …

Inventions On Generic Detection Of Computer Viruses -A Triz Based Analysis, Umakant Mishra

Umakant Mishra

The conventional methods of signature scanning and heuristic testing depend on prior knowledge of individual virus signatures and virus behaviors. Hence these methods are capable of detecting only the known viruses or viruses behaving in known ways. Hence, these methods cannot detect the viruses unless they are created, released and infected the innocent users. This situation creates the need for generic detectors that can detect even the new and unknown viruses.

The generic scanning methods, in contrast, don’t depend on individual virus signatures or behaviors. Hence they are better applicable to detect the new and unknown viruses and viruses of …

Methods Of Scanning Email Viruses - Applying Triz To Improve Anti-Virus Programs, Umakant Mishra

Umakant Mishra

An email virus makes use of the email technology and attaches itself to an email to transfer itself from one computer to another. Some email viruses create and send new emails using the address book of the victim computer. The email viruses are a matter of concern as they can spread very fast via emails to different geographical locations.

The conventional scanners are file based and not good for scanning emails as the emails can contain different types of files as attachments. Besides they cannot detect viruses until the emails are downloaded and opened by the recipient in order to …

Implementing Virus Scanning In Computer Networks, Umakant Mishra

Umakant Mishra

Some viruses exploit the features and capabilities of computer networks to spread, operate and damage network environments. For example, the virus may copy itself to other computers in the network or may increase network activities congesting the network traffic. The conventional anti-viruses are not efficient enough to detect and control viruses in a network environment. As they are file based they cannot scan the data while being downloaded from the server.

Most of the drawbacks of conventional scanning are taken care by a firewall-based virus scanning. But this method requires high-end machines to withstand the load of centralized scanning. There …

Why Is It Difficult To Find A Good Free Web Host, Umakant Mishra

Umakant Mishra

This article illustrates how the advertisements on free hosts are deceptive, the evaluations are fake, and the user feedbacks are manipulated. As a search engine cannot differentiate between good and bad free hosts per se, it is likely to serve you a list of free hosts, which are discussed more or advertised more and not necessarily better. Searching a good free host is as difficult as searching a diamond in a coalmine.

Should You Use A Free Server For Hosting Your Site?, Umakant Mishra

Umakant Mishra

Contrary to the general belief that the paid servers provide better service, the services provided by paid servers are often horrible. The matter of the fact is that you may not need much of service from a well-configured server. But the service provider wants to provide you service in order to prove its service efficiency. But how will they provide service when there is no need of service? So they have to create many artificial problems for you (e.g., by changing server configurations etc.) and then solve those problems promptly on your request, in order to prove their service efficiency. …

Parameters Of Evaluating Free Hosting Solutions, Umakant Mishra

Umakant Mishra

Before choosing a free server, it is important to evaluate its features in order to test its suitability for your hosting. This is particularly important as more than 90% of the so-called free servers are run by commercial hosting companies in order to attract customers for their hosting business. These so-called free servers provide very limited and conditional free hosting services and intend to sell their premium hosting packages to the free hosting customers in due course. Hence, it is important to not get carried away by their alluring advertisements rather evaluate each important aspect of the host, including its …

Overcoming Limitations Of Signature Scanning -Applying Triz To Improve Anti-Virus Programs, Umakant Mishra

Umakant Mishra

A virus signature is a sequence of bytes that may be found in a virus program code but unlikely to be found elsewhere. Signature scanning is a method of detecting a virus by scanning a target program to detect the presence of any virus signature. If the signature is found then the target program is deemed infected, otherwise the target program is deemed uninfected.

Signature scanning is the most popular method of virus scanning and is adopted by all anti-virus programs. Signature scanning is capable of detecting more than 80% of viruses. It uses a simple logic and uses less …

Solving Virus Problems By Anti-Virus Developers- A Triz Perspective, Umakant Mishra

Umakant Mishra

The anti-virus developers play a very significant role in dealing with the computer viruses. They analyze the problems of different levels of users and find solutions for each of those problems. Their goal is not just to sell the product and make profit out of it. They undertake much greater responsibility to ensure that their product meets the expectations of the users and deals with the viruses efficiently.

Different levels of users dealing with computer face different types of problems. The developer must ensure that the product meets the needs of various levels of users and network administrators. The developer …

Detecting Macro Viruses - A Triz Based Analysis, Umakant Mishra

Umakant Mishra

The macro viruses are easy to create but difficult to detect. Even for a virus scanner it is difficult to decide which macro is a virus and which macro is not, as a user macro may also create files, send emails and do all such activities that a macro virus can do. It is difficult to differentiate a genuine macro and a virus macro as both of them do similar type of jobs. Suspecting a macro to be virus just because it is “writing to a file” may result in false positives. It is necessary to improve the emulation method, …

Improving Speed Of Virus Scanning- Applying Triz To Improve Anti-Virus Programs, Umakant Mishra

Umakant Mishra

As the number of viruses increases the amount of time to scan for those viruses also increase. This situation is worsened because of the increasing number of files typically stored in a computer system. Besides more complex tests are required to detect the modern day’s intelligent viruses. Thus a combination of all these factors makes a full virus scan very lingering and resource consuming. With thousands of types of viruses and gigabytes of storages, a typical virus scanning may take several hours. Because of this reason many users don’t like to virus scan their computers unless so required.

Detecting Boot Sector Viruses- Applying Triz To Improve Anti-Virus Programs, Umakant Mishra

Umakant Mishra

The boot sector virus infects the boot record of the hard disk or floppy disks. It gets loaded onto the memory every time the computer is booted and remains resident in the memory till the computer is shut down. Once entered it alters the boot sector of the hard disk and remains in the hard disk permanently until the system is totally damaged and fails to boot.

While analyzing the problem from TRIZ prospective we try different possibilities to avoid boot sector viruses, such as, Can we do away with boot record? Can we avoid booting from floppies? Can we …

Triz And Society: An Alternative Way Of Winning Enemies Without Fighting, Umakant Mishra

Umakant Mishra

Although we are born and brought up in society, we are sometimes hurt by the offensive behavior of some people in our family and society, may be by the so-called friends or rivals or enemies. If we suppress our anger and don’t fight with them then we suffer from depression, frustration and other emotional disorders. On the other hand if we express our anger to fight back then the situation may become worse by inviting bigger fights and more violence. The question arises, how to solve this problem?

There are both fighting solutions and non-fighting solutions to this problem. Non-fighting …

Solving Problems Of Virus Definition Files - A Triz Perspective, Umakant Mishra

Umakant Mishra

Signature scanning is the most popular method of virus scanning and is adopted by all anti-virus programs. Signature scanning is capable of detecting more than 80% of viruses. It uses a simple logic and uses less memory and system resources. Although it has a lot of advantages, it has one big disadvantage. It requires the virus signature to be extracted by the experts and stored in a database called “virus signature database”. This virus signature database has to be updated by the anti-virus developers and the end users periodically in order to deal with the latest viruses.

A typical virus …
