Are computer viruses spread by the media?


If you believe what you hear in the media, there is a large amount of circulating virus. No, I'm talking about the guy-you-sick of the virus, even if you get plenty of airtime, too. I'm talking about the type of virus that enters through your Internet connection instead of the nostrils.

What the media often do not tell you - at least in most radio and TV news and headlines and excerpts of critical newspaper articles - is that many of these "viruses" are viruses all.

What viruses really

The main reason for the media are always on alert for viruses is that they tend to call any malicious program virus. In fact, there are at least eleven different types of malicious software, or malware, which usually affects computers today. The most common of these are worms, Trojans and spyware.

So, what is the difference between viruses and other malware? The difference is that computer viruses are almost the only ones that regularly shut down computers and cause visible damage. The most common types of malware - worms, trojan horses and spyware - are usually only be detected by a special examination.

The real danger of computer viruses

If other types of malware are so unobtrusive that can only be detected by a special examination, then what to worry about? For starters, these programs are called malicious for a reason: they are designed to cause no harm, if not at the computer, and then to another person.

Worms are the most popular used to damage, destroy or damage the computer to the network where the host. For example, the worms were used by website owners to close rival sites by sending a huge number of applications for the computer hosting the site. Worms have also been used to send viruses to other computers, often without infecting the machine - after all, what benefits the worm to turn off the computer?

Trojans, in turn, are often used to insert worms and other malware on your computer, even if the Trojan horse does not hurt.

But even if you do not care what happens to anyone else, you should be concerned about a type of malware: spyware, a type of malware that, true to its name, collects the data from the computer and sends it to a remote host remotely.

Most spyware is only interested in monitoring your internet usage so you can tell other programs, called adware, what advertising to appear on your computer. However, there are criminal spyware programs to steal financial data, or perform a deep identity theft. I do not think you have personal or financial data on your computer? Some spyware programs contain a keylogger, a program that copies everything you type, usually to get the passwords. Even if you do not keep financial information on your computer, if you ever buy something on the web, the keylogger that allows its owner to buy things with the same information you typed in to buy things for yourself.

Why blame the media?

Faced with the danger of all these different types of malware, not a good thing that the media are becoming hysterical about it? It can be forgiven the sloppy reporting of calling Trojans, worms, spyware and other malware "viruses"?

No, no, no.

This is a classic case of disinformation do more harm than no information. In this case, the damage report has done wrong is to promote a common myth that goes something like this: "The malware is just a virus damage your computer viruses, so if my computer is working fine, my computer .. no malicious software. I just have to scan your computer for problems when there is a sign of trouble. "

Thanks to this myth, many people complacent that their antivirus software go months out of date, did not want to be bothered with scheduling an automatic update. Equally bad, many people do not have any additional software to combat other types of malware that can not be covered by antivirus software.

In fact, it is not uncommon for people who have found malware on their computers after a scan to say, "but I never had malware on your computer before!" But how to know if he had never acquired!

Even the largest mainstream media - especially television - start educating the public about the need to have their computers automatically scanned at least once a day, the world will have big problems and prolonged contact with the malware could not be eliminated as soon as possible When the producers of anti-malware software detection.

And until that day, the media will have more opportunities to run hysterical stories of "viruses", forcing you to sell more newspapers and television for an even wider audience of people who suck in the information channel but somehow never so full.

Get The Facts About Wireless Laptops


Laptops provide portability incredible for all your computing needs, but as the need for communication grows more each day I need a team that will keep in touch. There are many options for mobile computing. Laptops now available in many different formats to meet your specific needs.

Screens big and small are the main factors influencing the size of a laptop. Optional accessories such as support units and larger batteries add the total weight of the laptops. The current trend for any traveler is to get the smaller computer to do the job. Airports have wireless internet, so a wireless network or wi-fi card is a good option. Large screens used to be popular but strict travel instructions have caused many people to get a small screen. In this way, make the computer easier to deal with security checks.

Main reasons for the trend of "less is more" with laptops is that they have become more than just a tool and less of a novelty. Most computers are very capable base in the management of all business applications and have the necessary options for general use. Base laptop also dropped in price dramatically. The options have become expensive than the competition grows fierce for the lowest price available on your computer. 

People are buying computers more frequently, with fewer options, because it is cheaper than buying new technology. Fast processors and large hard drives are initially very expensive and quickly become standard features on basic laptops. You can stay informed as to get a new laptop every two years instead of getting the latest technology and trying to make a duration of 4 years. However, most notebooks show a loss of performance after two years if the hard drive defragmentation and formatting. Can not seem cheaper than buying a computer more often, but what you buy. Doing a little shopping around and evaluate what you really need a computer can save the money you need to buy one more often.

Computer Printers - Cut Your Costs


When you buy a new computer is almost always provided with a free printer. The printer is almost always a free inkjet model. The printer manufacturer gives these to the computer manufacturer for a low blow losing money as a leader. What most people do not take into consideration is the cost of replacing inkjet cartridges in a few weeks, and on a monthly basis thereafter.

The real laser printer is now down to a price where it is comparable to an inkjet printer, even for domestic use. Many families have 2 inkjet printers for color work, and a laser printer as the default.

Even if you have to pay for a laser printer operating costs will run much less than the ink free. Once people take into consideration the cost of a laser printer ink is dull only about one third the annual cost of an inkjet printer. The best thing you can do is set the laser printer and inkjet free. Make sure that the laser machine is set as the default printer. Disconnect the ink to prevent it being used unnecessarily.

What about filling inkjet cartridges? Forget it, the quality of the charge is simply unacceptable.

Remanufactured laser cartridges are to be taken into account, especially for daily use as a printer and internal as the Internet. Laser toner cartridges are highly engineered for use in precision. Yet, many people simply throw away, rather than send them away for reuse. Reuse is always less expensive for our environment recycling. Re-use is to replace worn parts and refill the cartridge with toner powder. Recycling provides breaking the cartridge and the merger of various plastic down separately.

There are many companies that offer this service and once you find one that offers a quality of remanufactured cartridges for your printer model, you would do well to stick with that company. You can always find cheap, presumably remanufactured laser cartridges, but these are just filled, and often none of the worn parts replaced.

Insist on a "money back if not satisfied" guarantee.

Tips On Buying Software


DON'T BUY ON PRICE

Unfortunately, there is no corellation between price and quality of software. Expensive software may or may not have features found or not found in less expensive software. Decide how much you can afford, then evaluate the software you can afford on it's own merits. Don't buy software because of its purchase price. Look at what it will do for you and the long term costs.

DO EVALUATE THE SOFTWARE

Be sure to try a demo of the software before you purchase it. Only you know if you can run the software and if it'll do all you want. Beware of slide show demos that don't let you run the program. Don't let claims and fancy brochures sway you. Insist on working demos so you can evaluate the software. While you may be able to learn the software, you don't want to spend days teaching new employees. Look for ease of use. Software is a tool to make life easier and more productive. You're not purchasing software to waste your time. DON'T BUY UNSEEN! 

Our demo programs are the actual program with obvious limitations built in. Unlike slide show demos where you cannot interact with the program, our demos allow you to see exactly how the program works and how it works on your printer. You should never have to purchase software unseen. Only you know if you can run the software or if it will do what you want. Software is a tool to make life easier and more productive. Don't buy sight unseen.

DO SEE HOW LONG THE SUPPLIER HAS BEEN IN BUSINESS

Software suppliers come and go like flies. While you can't be sure the supplier will be around 10 years from now when you need him, the longer he's been in business, the better the odds. 

DO READ THE FINE PRINT

Look for catches like: versions, maintenance fees, tech support charges, upgrade options, forms costs, networking charges, etc. Read the warrantee.

DON'T LET THE MONEY BACK GUARANTEE FOOL YOU

Ask for names and telephone numbers of some customers who got their money returned. See how easy it was to get the refund. Evaluate the software before you part with your hard earned cash. Do not buy software you haven't tried just because of a money back guarantee. 
We offer free working demos so you can evaluate our software before purchase. Because software can be copied, all sales are final. We do not inflate our prices to cover the cost of software theft. 

Data Recovery and Your Computer


Have you ever wondered if you know what data recovery is accurate? Consider the following paragraphs and compare what you know the latest information about data recovery.

Sooner or later, your company could become the victim of a natural disaster, or something much more common as a storm or power lines down.

The fact that your company may be a small business does not mean it is immune to data disasters. If a small business does not have a disaster recovery plan and a good test in place when disaster strikes you never fully recover and can also make it off the market. Sometimes, even a data recovery service may be of some help.


Here are some questions that should be resolved in order to give you an idea of ??what you need to do to help you if you have a data disaster situation.

Do you know where the files are the most important company data?

These files are backed up and by what means?

How often do you perform these backups and data are verified and tested?

Automated checks that you have correctly and consistently doing backups?

Your backup tapes off-site data to go and how often?

Do you have any kind of security against tampering or theft of data backup?

Do you keep your servers, routers, hubs and controllers telephone system in enclosed areas to keep them safer?

He just anyone to access the server and the technological resources and limited access to at least two but no more than four people?

It prevents unauthorized boot-up or tampering with configuration settings through the BIOS power-on password?

On your desktop and notebook PCs, as are major upgrades, service packs and releases constantly updated?

The bottom line is that you can not plan when a disaster can strike data but taking a few steps before it can help with the survival of your company in the days and weeks following a disaster.

A Look At The History Of Notebook Computers


A notebook computer is a term used interchangeably with laptop computers. For those of you not familiar, a notebook computer is one that is smaller and lighter than a personal computer. You can take it with you anywhere so it offers you more access to the internet, a way to watch movies, and even a way to work while you are away on business trips.

The first notebook computer was introduced in 1981 but they were very expensive and not as versatile as they are today. IBM and Epsom both placed versions of portable laptops on the market in 1983. Even with more models emerging, notebook computers were an item often associated only with high profile businessmen.

It wasn't until 1995 when Microsoft introduced their operating system Windows 95 that the world of notebook computers exploded. This operating system along with advances in technology that allowed notebook computers to function in the same ways as a personal computer led to them dropping in price and more consumers buying them.

Some of the improvements that occurred around this time were a better battery that no longer included acid. Power saving notebook computers were introduced so the life of the battery lasted much longer. They also were now able to hold more data so they could be used for more concepts at any given time.

Today you see people of all ages carrying their notebook computers to the office, home, on airplanes, colleges, and hotels. Many public places are set up with areas for individuals to conveniently use their laptops. Since we live in such a computer age having a notebook computer can help you stay on top of things for work and pleasure no matter where you go.

You can find notebook computers in a variety of sizes and from multiple manufacturers. They come with a good price, plenty of storage capacity, and warranties. If you are in the market for a notebook computer you will have no trouble finding exactly what you are looking for.

Monitor Buying Guide Tips


Panel technology 
CRTs have effectively been replaced by their thinner and brighter sister, the LCD. Under the umbrella of LCD technology, there are a few choices to consider before buying a monitor. First, you'll have to decide which panel technology is right for you.
The three main panel technologies currently used in LCDs are: twisted nematic (TN), vertical alignment (VA), and in-plane switching (IPS). Manufacturers make the vast majority of consumer monitors using TN panels.
Not surprising, TN panels are the cheapest of the three technologies to make. With a few exceptions, monitors that cost $300 or less will likely have TN panels. The main advantages of TN panels are their fast--usually 2ms--response time and, of course, low price. Their major disadvantages are narrow viewing angles, relatively low brightness, and inaccurate color reproduction.
Next up are VA (mostly seen as S-PVA) panels. VAs have improved viewing angles compared with TNs, better color reproduction, and they typically have a much higher maximum brightness. Also, they tend to have the lowest black levels of all three panel technologies. Unfortunately, a VA panel's response time and input lag are not quite as fast as a TN panel, and they can cost anywhere from $400 to $800, and sometimes more depending on the panel's size. Also, you can expect a VA-based monitor's profile to be wider than a TN's.
Lastly, we have IPS. IPS-based monitors are usually the most expensive; however, the new e-IPS panels cost as little as $300 for a 22-inch model. They also have the best viewing angles of all three technologies and produce the most accurate colors; however, their blacks are not as deep as VA panels'. IPS monitors are the slowest of the bunch in both response time and input lag.
Backlight
Let's clear this up right away: LED and LCD technologies are not mutually exclusive. To ask what their differences are is like asking what the difference is between Vibram Five Finger shoes and rubber soles.
So let's break down what LCDs and LED backlights are, as they relate to monitors, and delve into the real advantages of LED backlighting technology.
The term LCD stands for liquid crystal display. LCDs are an upgrade (in most respects) from tube-based CRTs (cathode ray tube) from years of old, although some still prefer CRTs over LCDs. In short, LCDs use liquid crystals to express what you see on the screen. The crystals act as a shutter for the backlight, and, depending on the type of charge given to them by the monitor's built-in electrodes, the crystals will either allow light through to the user or shut it out, thereby allowing the pixels to express their appropriate colors, making up what you see on the screen.
LED-based monitors are still LCDs (they still use liquid crystals to express images onscreen), but they use a different type of backlight than what is normally used. Most monitors of the last few years have used cold cathode florescent (CCFL) tubes as their backlight of choice.
Today, more monitor vendors are fully embracing LED backlight technology, with Viewsonic recently announcing that it's shifting its entire monitor line to use LED backlights.
To understand LED backlights, you must understand the three types currently being used in modern computer monitors.
Types of LED backlights
First up are edge-lit backlights using white LEDs (WLED) or EL-WLED. This is the type of LED backlight most commonly used in today's monitors. This entails white LEDs aligned along the edge(s) of the monitor matrix, right behind the liquid crystal array.
Using a special diffuser, the light is spread to cover the entire screen. Monitor vendors have recently refined the technology so that only one edge (not four) need be outfitted with LED lights.
The EL-WLED solution is the cheapest and smallest of the three technologies, which is why it's the most widely used. The advantages of its small design can be seen in displays like the superthin AOC e2243Fw and Samsung PX2370. You'll also see these used in many notebook and Netbook screens, and recently HDTVs have begun adopting the technology as well.
Our next technology is RGB LED. Instead of using white LEDs on one edge of the screen like the previous technology, RGB LEDs are aligned all over the panel matrix.
Each individual light is capable of producing red-, green-, or blue-colored light. This gives the display access to a high color gamut with colors more accurate than what's capable on EL-WLEDs.
Unfortunately, you won't see this technology in use everywhere, as it's very expensive and doesn't allow for a thin design. The $3,500 HP DreamColor LP2490zx uses RGB LED backlights, and its panel measures about 2.25 inches, compared with the $300 Samsung PX2370's 0.6-inch panel depth.
The final type is WLED on a flat array, covering the entire screen. Think of it like an RGB LED that's only using white LEDs instead of tricolor ones. Currently, it's only used in LED-backlit HDTVs; CNET's own David Katzmaier writes about it in depth here.
This brings us to the real question you should be asking: what advantages do LED backlights provide over CCFL backlight solutions? Well obviously this depends on the type of LED backlight; for our purposes, we'll discuss the two used in modern LED-based computer monitors: EL-WLEDs and RGB LEDs.
The following are the most frequently touted advantages of LED-based monitors. Let's get to the bottom of them.
LED backlit monitors have high color gamuts and provide more accurate colors.
Color gamut is controlled by the monitor's color filters and the backlight's radiation spectrum. While CCFL-based monitors typically offer between 72 and 102 percent of the NTSC color space , RGB LED can cover up to 114 percent. EL-WLED does not offer high color gamuts and typically hit around 68 percent of the NTSC color space.
When it comes to color accuracy, before the backlight can be a factor in the precision of a monitor's colors, the display itself must first be capable of producing a high color bit depth. While the color gamut refers to the range of colors a monitor is capable of producing, bit depth determines how many steps of those colors are within that range. The HP DreamColor LP2480zx for example has a 10-bit panel, which allows it to theoretically produce 1.07 billion different colors. Most monitors are limited to 6-bit panels, allowing only 262,000 colors, but through a few technical tricks can "fake" up to 16.2 million colors.
The use of RGB LEDs for backlighting can provide a color spectrum that closely follows the color filtering in the LCD pixel itself. This method allows the color component to be very precise with the color it's using. Also, each individual RGB LED can be tailored to produce the most vivid colors. EL-WLED backlighting is not capable of influencing color in this way.
LED backlit monitors are always superthin.
Only if they're using EL-WLED backlights, as most LED-based monitors do. It's a trade-off between cost and performance. RGB LED provides incredible color performance, but is expensive and bulky. EL-WLEDs don't really influence performance, but can produce monitors less than an inch thick.
LED backlights have lower power consumption.
Yes! At least EL-WLED backlights do. Well, for the most part. The biggest factors that affect monitor power consumption are screen size and luminance. Check out our most recent monitor power consumption chart. Most of the LED-based monitors (all using EL-WLED) are rated as "Good."
LED backlights take less of a toll on the environment when it's time to dispose of them.
True. CCFL technology makes liberal use of mercury, and thanks to the element's high toxicity level, can be a danger to the environment. LEDs contain no mercury and can be recycled much easier.
For most consumers (buying EL-WLED), LED-based monitors will offer low-power-consuming thin panels that are much easier disposed of than CCFL-based displays. Beyond that, unless you're willing to shell out $3,500, that's all you get. Not to shake a stick at power consumption or the environmental impact your purchases have, but you should know where you stand when browsing through the monitor aisle at Best Buy.
The real question is: when will vendors began offering more than just TN-based LED monitors in great numbers? Both BenQ and NEC have made some announcements in this regard this year. Keep an eye on the monitor hub for more coverage on this.

Tips to Protect Your portable external Hard disk drive Disk


Below are the simple but effecient tips which increases life of your Hard Disk.

The hard disk goes through thermal stress each time the PC is turned off and on. The hard disk in your PC uses up incredibly little electricity when it is in an inactive state. You may feel that you're increasing your power costs by keeping your PC on, but remember that's better than dealing with hard disk crashes!! and the consequent loss of data as a result of switching your machine off and on too many times. You are better off leaving your PC on than trying to save electricity and turning it off several times in a day. So reduce the number of times you turn your PC on and off.

Turn The Monitor Off:

One can protect hard disk by limiting the number of times you turn the PC on and off during the day since each time you do this the hard disk goes through thermal stress. However you should turn off just the monitor when it's not going to be in use for more than a couple of hours. This will help make the monitor last longer because the CRT [Cathode Ray Tube] that makes up most of the monitor lifespan is limited and related to the number of hours it is left on. Moreover remember that most monitors consume as much power as the PC itself.

So even while you are protecting the hard disk by leaving the PC on, you can protect the monitor plus save power by turning just the monitor off. Since monitors take just a couple of seconds to display, there isn't even an issue of `waiting' as in the case of a PC which takes a few minutes to boot every time you turn it on.

Nothing Should be kept On Your Monitor:

You would have noticed that the top of your monitor has ventilation, that's because monitors like your PC get heated up when in use. To extend the life of your monitor [and your television set, whether you are watching channels or using the TV as a PC]be sure that you do not place anything on the monitor.

For Crashing Components follow simple steps below :

Sometimes what seems like a disaster in the PC's system may actually be a minor problem. However, there will be times when you must bite the bullet and either repair or replace an expensive component. What you do depends on several factors, including the relative age and value of the damaged components and the prospect of actually repairing it.


If you do need repair help, you have several choices:

* If the component came with a system that is under warranty, contact the vendor for service. Often you will be able to avoid the cost of repair and will simply receive a new replacement part directly from the system manufacturer.

* If you brought the component separately, check its warranty. If it is still covered, contact the manufacturer.

* If you purchased a new peripheral or system and it failed to work [called 'dead on arrival' or DOA] you should be able to return it for a new part, or a full refund!

Out of warranty repairs can be conducted by technicians at your local computer store, ranging from single store small shops to regional and national chains.
