Warding Off Viruses

March 10th, 2010

Shielding your computer from viruses is becoming more and |more difficult each day. While it may sound a bit paranoid, it is true that you cannot let your defense drop for one second. Even corporate giant Microsoft has found its own computers compromised on more than one occasion.

Do you remember the ‘good old days’, before the arrival of the Internet and downloadable programs? Life was simple then in terms of computer viruses. The primary way to catch a virus then was via floppy disks. By today’s standards, it used to take quite a while before a virus was able to infect a computer and slow down the system. The antivirus software of that time was usually able to identify and eliminate viruses before they caused too much harm. Additionally, computer users were fairly knowledgeable about how to defend themselves by scanning all floppy disks before using them.

The Internet changed all that. The Internet provided a conduit by which viruses could move from host to host with lightening speed. A computer user had to begin to think about email, email attachments, peer-to-peer file sharing, instant messaging, and software downloads as virus entry points. Today’s viruses can attack through multiple entry points, propagate without human involvement, and take full advantage of vulnerabilities within a system or program. With technology advancing everyday, and the convergence of computers with other mobile devices, the potential for new kinds of threats also increases.

Luckily, the advancement of antivirus software has kept up with the virus threats. Antivirus software is essential to a computer’s ability to ward off viruses and other malicious programs. These software products are designed to guard against the ability of a virus to enter a computer through email, web browsers, file servers and desktops. Moreover, these programs offer a control feature that handles deployment, configuration and updating. A computer user should remain diligent and follow a couple of simple steps to guard against the menace of a virus:

You should evaluate your current computer security system. With the danger of a new generation of viruses being able to attack in a multitude of ways, the tactic of having just one kind of antivirus software has become obsolete. You have to be sure that you have protected all aspects of your computer system from the desktop to the network, and from the gateway to the server. Think about a more wide-ranging security system which encompasses several features including antivirus, firewall, content filtering, and intrusion detection. This type of system will make it more difficult for the virus to penetrate your system.

You should install antivirus software created by a well-known, reputable company, because new viruses erupt daily, so it is important that you update your antivirus software daily. Become au fait with the software’s real-time scan feature and configure it to start automatically every time you start up your computer. This will protect your system by automatically checking your computer each time it is powered up.

Set your antivirus software to scan all new programs or files no matter from where they originate from and exercise caution when opening binary, Word, or Excel documents of unknown origin particularly if they were received during an online chat or as an attachment to an email.

Make sure you perform regular backups in case your system is corrupted. It could be the only way to retrieve your data if you computer becomes infected.

There are many applications available to consumers, so with a little research, you should be able to pick the program that is right for you. Many programs offer a trial version which allows you to download the program and test its capabilities. However, be aware that some anti-virus programs can be difficult to uninstall, so as a precaution make sure you set up a System Restore point and take back-ups before installing it.

The High Tech Notebook

March 6th, 2010

Nowadays, the majority of people know all about the importance of computers. These technologies can be found almost anywhere from coffee shops to internet cafs. A lot of businesses don’t matter if they are big or small companies make use of the computer and some people use it ever for personal use, to chat, to surf, or to type some important documents. But with the growing demand of computers, people also demand more portable and movable computers. And for that reason, they created the notebooks.

Notebooks or what is also known as laptop computers are small, compact and portable computers. A notebook computer is a very lightweight personal computer. Notebook computers characteristically would weigh around two to eighteen pounds but that would depend on the size of your notebook computer in addition to that it is also small enough to put in a briefcase.

Aside from being portable and small, the foremost dissimilarity of a notebook and a personal computer would be their display screen. An external adaptor is used to operate a notebook and a single battery as well. The battery pack used by a notebook needs to be recharges once in a while.

Through these battery packs, a person with a notebook computer will be able to operate the computer with no external adaptor. Plus, you can also make use of the notebook just about everywhere you want to go.

The method used to in favor of notebook computers or laptops are the flat panel technologies. Through this method they are able to generate a lightweight computer and a screen that is not massive. The quality of the notebook computer would be radically different. A great number of the display screens of the notebook are limited to VGA resolution. Even though active matrix screens are competent to generate exceptionally clear imagery, they do not restore as rapidly as the full sized monitors do.

Regarding the computer power, new notebook computers are practically the same with a personal computer. They have very similar memory capacity, disk drives and CPUs. On the other hand, all this power contained in a small package does not come without a price. These notebooks are quite expensive.

There are numerous types and prices of notebook computers. A few of these are: o Mini Notebook – small and portable. Starting price of $299 o Ispiron – value and style. Starting Price $399. o Studio – design and performance. Starting price $599 o Alienware – ultimate gaming laptop. Starting price $1,199

There are a lot of choices to choose from. You can also look for available notebook computers with the use of the every reliable World Wide Web otherwise known as the internet.

If you are searching for high superior Netbook Computers for professional or home use make certain check up on various types of Laptops to guarantee that you will find the best deal possible.

What Makes Hadoop Tick?

March 5th, 2010

A lot of people value the importance of programming when doing some applications. This is due to the fact that it is important to know how to run the codes for the application. Aside from this, the code listings can also trigger questions that deal with the possibility and operation of various business and games software. Hence, they serve as good business tools for each business operation to be a success.

For leading search engines like Google, they utilize MapReduce for indexing purposes. This is a dynamic application that can improve the task of searching in a faster rate than it was before. MapReduce is made up of two important parts which are called Map and Reduce. Map is the data processing where the information would be assigned to be gathered in the form of clusters. Reduce would separate the date to be able to arrive at an individual value.

Nevertheless, Hadoop is also very helpful to MapReduce. It serves a very crucial role in the process of the MapReduce. Hadoop is included in the project of Apache that was made by various contributors worldwide. It is a great example of Java software skeleton that can be beneficial for the processing of software that is data-extensive.

Upon hearing the term Hadoop, a lot of people may start to ask what it really is. What characteristics can describe it? Overall, there are three primary characteristics that it is comprised of that can help people understand it better. These characteristics will also be helpful in how it is connected with MapReduce in terms of running it.

The main characteristic of Hadoop is its data parallelism through the entire process. For instance, the parallelism can occur in two processing systems. It is essential that it is not entirely possible for it to occur all at the same time. This just means that it is very crucial for the completion of the Map before the occurrence of the phase for the Reduce.

The next characteristic is that Hadoop will process the needed information in chunks or batches. Again, the Map process should be finished first before starting the next phase. The data would be frozen until the whole Map process is done.

The final characteristic would be the distribution file system needed for the communication of the data. The response time for this phase may take some time since the acquisition of data is needed to have the data to be moved around inside the system as it duplicates with synchronicity.

For indexing purposes, Hadoop is very essential in terms of framework to help in finishing the tasks properly. There are lots of computer experts that will see the relevance of this framework due to its amazing benefits.

Hadoop technology is a program specially designed to support systems that require a large amount of data. Although possibly confusing at first, working side by side with MapReduce technology, which ensures the tasks you have designated are completed properly.

The Benefits Of Data Mining And Data Analytics

March 1st, 2010

Nowadays, it is true that research has been one of the processes that made a difference to a number of industries and companies. The reason for this is that research helps companies to improve their products that they produce or the service that they render. Primarily, this will tell them when the product would need some improvements since it causes some problems or whether the services have not reached the appropriate standards set whether by the companies or the authorities.

Research has two factors that make it work properly for different industries. It utilizes both data mining and data analytics to help them arrive on important decisions within the company. Data mining means important raw data that would be taken from certain tests and make them useful for their companies. This data is taken from a number of test results that companies usually do.

Once the data is taken out, the research professionals will now do data analytics. This is the procedure where the drawn out data will be used to draw out conclusions for the industry. These conclusions will dictate whether there is still a need for them to improve the things that they currently do like manufactured products and service.

It is very important that any data be as accurate as possible. With this, you can have the simple data as your proof already. Hence, if a test product does not reach a certain standard for quality, then it can be concluded that it won’t be able to serve the customer properly.

Take for instance that a product will be tested to determine it is being effective. Once the product being tested passes their standards, then the company can precede manufacturing the product. If it won’t pass the test, then it must go through another set of improvement processes during production.

Another possible thing about testing is to get the data that the company will know whether they can continue on doing the same thing in production or company system or not. This will prevent the company from incurring problems if the product or service has not served the clients properly.

Data mining and data analytics are not just useful when it comes to testing procedures but also in other aspects of the industry. It can be used to double check the performance of various equipment, machines, manpower and other resources being utilized by the company.

So In conclusion, doing data mining and data analytics is certainly helpful for company improvements. This is a way of knowing if they maintain the important factors that will contribute to their success. As long as they do a number of testing, they will have enough information to draw out accurate conclusions in the process.

Understanding The Functionality Of The MapReduce Framework

February 25th, 2010

Google developed the MapReduce programming framework as a means to process massive amounts of data in a fast and effective manner. Originally it was created to help deal with so much data that it had to be spread out across thousands of individual machines.

This kind of data processing doesn’t always have to be on such a large scale. Smaller companies can also make good use of this framework to organize data and discover new statistical relationships. MapReduce functionality will provide a method to analyze your data no matter how much or how litter there is.

Whether your data set is large or small, you can use a MapReduce application to query the system for very specific information. With the right information to work with, you will be able to manage fraud detection, work with graph analysis, explore sharing and search behavior, and monitoring the transformations. These are functions that were hard to manage, especially in data sets that were continually growing.

When you submit a MapReduce job it will be split up into more manageable jobs that can be processed when it is assigned by the map task. It will work in a completely parallel manner to accomplish this. The program will then output the maps into a reduce task, which, in the long run, will help you use all the resources of a large, distributed system.

When the system has split up the information and it has been reduced, users can employ MapReduce functionality to handle the rest of the process. This includes the scheduling, the monitoring, and any necessary re-executions of failed tasks. When these tasks can be automated, it will lighten the burden of your data mining activities.

One option is to use the Hadoop API to interact with MapReduce functionality. You need to make sure that all data transfers and job configurations are correct and consistent in order to maintain the integrity of the data base. The API is the way that many companies are developing new and reliable methods to discover important facts in their data.

When you use the Apache Hadoop API, you can submit and configure a job to the job scheduler which will then distribute the tasks to the worker nodes or systems within the cluster. The master system (job scheduler) will then schedule and monitor the necessary tasks and even provide status and diagnostic information as you go.

By using the functionality built into MapReduce applications, you will be able to effectively process your data, even if it is set up on thousands of different machines. You might consider this as an option if you are looking for a way to track customer behavior or just to transfer data from one system to another.

Working along side with MapReduce, Hadoop API technology is a framework designed to support applications that require lots of data. This technology can be confusing at times but ensures the work is completed properly.

The Distinction Between Hardcore And Casual PC Games

February 25th, 2010

A lot of people like to argue about the difference between “casual” and “hardcore” gaming. Any new PC game is likely to claim to be one or the other in order to fit into the current marketing efforts. But is there really much of a difference? Does your current interest in PC or online games really classify you as one or the other? Why not just play what you feel like?

What does it take to make a PC game casual or hardcore? It wasn’t that long ago when a “casual game” would have simply been called a “family game.” However, that kind of branding doesn’t sell as well anymore. Still, a casual PC game would have to be defined as the ones that appeal to the widest demographic (or every part of the family).

On the other hand, hardcore games only need to appeal to a specific group – generally the kind that likes to watch things blow up. If nothing seems likely to explode any time soon, they will settle for a high fantasy or hard science fiction theme. Hardcore gamers also like online games that offer a certain amount of competition.

Then there are the Massively Multiplayer Online Games. These came out a number of years ago and were quickly taken over by the hardcore gamers. People spent hours on end just hunting down angry rats in an attempt to “level up” once more before signing off. Now, though, these games have crossed over into mainstream popularity, so does that mean they can be considered a “casual” PC game?

There’s no real reason to group gamers like that. The gaming industry keeps growing and turning more mainstream, and the line between the two classifications will keep blurring. Hardcore gamers will satisfy their competitive nature on the simplest games, and casual gamers won’t be able to resist the chance to blow up virtual items for entertainment.

Where would you even classify things like sports or racing PC games? These don’t quite fit so easily into one category or the other. They appeal to a wide audience, but they can also meet the needs of die-hard sports, racing, or gaming fans. These games can also help move one type of gamer to another category for a while.

As the gaming industry develops, more and more people will get involved with it and then no one will be able say whether the hardcore gamers or the casual gamers will dominate the market. Lately, that position seems to go back and forth quite often.

In the end, it will always be about your own preferences. After all, there’s no reason you shouldn’t try putting down the guns for a while to challenge your brain with a puzzle game, or to set aside the cute minigames to try your hand at the newest shooter or strategy PC game on the market.

As gaming becomes ever more popular, people are turning to online games as a major source of fun. Not only that, a PC game willgive you hours on end of fun. Don’t miss out on gaming. Grab a totally unique version of this article from the Uber Article Directory

Securing Your Computer System

February 19th, 2010

Today, more and more people are using their computers for everything from communication to online banking and investing to searching. As we do these things on a more frequent basis, we open ourselves to prospective hackers, attackers and crackers.

While some may be looking to phish your personal information and identity for resale, others want to use your computer as a platform from which to attack other unsuspecting targets. Hereunder are a few easy, cost-effective steps you can take to make your computer more secure.

1. Always make backups of important data and store it in a safe place away from your computer.

2. Update and patch your operating system, web browser and software frequently. If you have a Windows operating system, start by going to windowsupdate.microsoft.com and running the update wizard. This program will help you find the latest patches for your Windows operating system. Also go to officeupdate.microsoft.com to locate possible patches for your Microsoft Office programs.

3. Set up a firewall. Without a good firewall, viruses, worms, Trojans, malware and adware can all access your computer from the Internet easily. Thought should be given to the benefits and differences between hardware and software based firewall programs.

4. Check your browser and email settings for maximum security. Why should you do this? Active-X and JavaScript are often used by hackers to plant malevolent programs into your computer. While cookies are relatively harmless in terms of security matters, they can still record your movements on the Internet to build a profile of you. As a minimum precaution, adjust your security setting for the ?Internet zone? to High, and your ?trusted sites zone? to Medium Low.

5. Install antivirus software and set for automatic updates so that you get the most recent versions.

6. Do not open unidentified email attachments. It is simply not sufficient that you may know the address from which it originates because many viruses can be spread from a familiar address.

7. Do not run programs from unknown sources. What is more, do not send these kinds of programs to friends and colleagues because they contain funny or amusing stories or jokes. They may contain a Trojan horse just waiting to infect a computer.

8. Disable hidden filename extensions. By default, the Windows operating system is set to ?hide file extensions for known file types?. Disable this option so that file extensions show in Windows. Some file extensions will, by default, continue to remain hidden, but you are more likely to see any strange file extensions that do not belong.

9. Switch off your computer and disconnect from the network when not using the computer. A hacker can not strike at your computer when you are disconnected from the network or the computer is off.

10. Create a boot disk on a floppy disk or CD in case your computer is damaged or compromised by a malicious program. Clearly, you have to take this step before you are subject to a hostile breach of your system security.

If you are looking for new custom PC cases, or any other type of computer case, just go over to our website now at Clear Computer Case for more information.

The Antivirus Industry

February 15th, 2010

Most computer enthusiasts in the United States have heard of the foremost American antivirus vendors. Manufacturers such as Symantec, McAfee, Computer Associates, and Trend Micro. These organizations have a market leading presence in the United States. Microsoft, too, has plans to become a major player in this huge growth industry.

In fact, Microsoft bought intellectual property and technology rights from GeCad software in 2003, a company based in Bucharest, Romania. They also acquired Pelican Software, which had a behaviour based security product, as well as the Giant Company Software for spyware and Sybari Software, which managed virus, spam, and phishing filtering.

A great deal of discussion centered on whether Microsoft would end up in a dominant place in the antivirus market by merely bundling its newly acquired software technologies up with its Windows operating systems at no charge. This is a comparable technique that has been applied in other markets such as word processing and Internet browsers. In fact, this is exactly what did take place. Microsoft has come out with a free product called Microsoft Security Essentials.

It is too soon for me to advise whether MS Security Essentials is a world-class antivirus product, but it is not free to everyone. Microsoft has been battling Windows piracy for a while now with its Windows Genuine Advantage sneaky download and sure enough, this new product from Microsoft will only work on Windows systems and even then, only with operating systems that pass the Windows Genuine Advantage test. (Please click the link at the bottom the page to find out more).

There is nothing wrong with that per se, but it does mean that hardly anyone in the Third World will be able to make use of it, because a pirated operating system comes bundled with every computer that I have ever seen in Asia and probably elsewhere too. People save for years in order to afford a computer and the last thing they worry about when they plug it in is whether the operating system is genuine or not.

Of course there is a number of other antivirus manufacturers prominent in this market. There are many companies with great market presence in other countries that are beginning to become more widely recognized. These vendors include GriSoft from the Czech Republic, Sophos from the United Kingdom, Panda Software from Spain, Kaspersky from Russia, SoftWin from Romania, F-Secure from Finland, Norman from Norway, Arcabit from Poland, VirusBuster from Hungary, Nod from Thailand and AhnLab from South Korea.

It is not yet apparent where the industry is heading and everyone in this market is confronted by a swiftly changing landscape. The amount of effort necessary to discover and deliver updates for new viruses is quite staggering. Malicious programs are getting more and more complex and the quantity of them is increasing.

Many companies may find themselves without the resources to match the efforts of those truly determined to create havoc. The antivirus companies are getting hundreds of new examples of viruses a day! What is more, the new viruses are getting “cleverer” in that they propagate themselves quickly and they often hide themselves too. Some are even smart enough to move around in a system by renaming themselves in an effort to make it hard to remove them.

Owen Jones, the author of this article, writes on many subjects, but is currently involved with researching the Microsoft antivirus software. If you have an interest in such software, please go over to our website now at Computer Antivirus Software
