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.

Antivirus Software - A Must-have Protection For Computers



With the advent of computer viruses of all kinds, antivirus software installation in PCs has become a necessity. The antivirus software comprise of computer programs which strive to identify viruses and 'malware' (other malicious software), thwart their endeavors and eliminate them altogether. 

About Antivirus Software

The antivirus software program may come installed on your computer or may be purchased and installed by you. There are quite a few 'invaders' against which the computer needs to be protected against. There are the viruses, worms, Trojan horses and so on. The best antivirus software available is geared to offer protection against the whole range of such known viruses and malware. The potential damage that viruses can inflict such as deletion of files, unauthorized access to personal data, and usage of the computer as a platform to carry out attack on other computers, can all be thwarted by installing at least one of the top ten antivirus software products. 

Techniques Used By Antivirus Software

The antivirus software usually uses two alternative techniques. It scans files for viruses that match the definitions given in virus dictionaries, or it identifies infection indicated by suspicious behavior from some computer program.

Some of the best antivirus software come for free. Usuaslly the best free antivirus software adopts both the techniques. However, the best antivirus software packages put special emphasis on the virus dictionary matching approach. 

Features To Look For In The Best Antivirus Software Packages

Look for the following features when purchasing an antivirus software product of choice:

Simplicity and ease of use of the software so that even a person with little knowledge of computers or viruses can use and install it.

Effectiveness in identifying viruses, worms and the like is a desirable feature of the best antivirus software products.  

Efficacy in cleaning out or isolating of files already infected so as to prevent further infection is another important feature that should be included in any good antivirus software. 

Each of the best antivirus software products assure high level of security for Windows based PCs. Depending on the uniqueness of the system in use you can choose from among the top 10 antivirus software products available from online sources.

Adware tale of the computer hijackers




When we think of adware, what comes to mind are those annoying and pesky ads that pop up out of nowhere whenever we are surfing the net. Anybody who has surfed through the net has encountered those irritating pop-up adwares advertising everything from computer software down to Viagra. Adwares are some of the most derided objects in the web alongside viruses, spyware and other malicious softwares and programs. Although adwares are alleged to be the most benign form of spyware, most web users hate the blatant and bothersome way of advertising. Most are often tricked into clicking on such adwares and end up unintentionally downloading something far more serious. 

What are adwares, anyway? Adware or advertising-supported software is defined as any computer program or software package in which advertising and other marketing material are included with or automatically loaded by the software. Adwares are usually played back after installation. Some malicious adwares upload information about the computer or its user's activities even without the consent of its user. Adwares most often take the form of banner ads that appear on pop up windows or anywhere on the computer screen.

Software applications display these advertising banners whenever a program is opened or through some other triggering mechanism. Most adwares are integrated into a free application. This is a way for the developers to recover the costs of creating such software. A prominent example of this is the Opera browser software, which is a free application but comes with a banner ad. The adware can only be removed once the user purchases and registers his copy of the software. It is also a revenue-generating mechanism. A company can sponsor adwares to capture more visitors and potential customers. Adware as a marketing strategy is just one of the many techniques used by websites to attract more traffic.

However, some adwares are more than just pesky and garish ads. In many cases, adwares accompany a more malicious program, which uploads information about the user collected without permission. The users surfing habits are then tracked; in some cases, the browser home page is altered or redirected to the adware company's sponsoring site. These types of adwares are dangerous since they may jeopardize the computer system's health. Aside from installing malicious software, they may also become an avenue for viruses to invade the system.

Adwares have come under fire not only because of their annoying presence in the form of pop ups and banners but also in the way they invade the privacy of the user. Trackware and Spyware are just two of the "evil" forms that adware can take. That is why most computer users make an effort to get rid of these adwares. Because of the annoying nature of pop-up adware, most browsers now employ an adware blocking system through the form of a pop-up blocker or adware blocker. Browsers such as Microsoft's Internet Explorer and Mozilla's Firefox all use pop-up blockers, which instantly block or close any window that is triggered by adware in the sites that the user visits. These steps have significantly reduced the number of irritating adware that pop up every time a site is opened. 

Most antivirus programs and utilities now feature an adware search and removal system. These programs indexes known adwares and spywares in the internet universe and searches for it in the user's computers system then subsequently quarantines or deletes the malicious files. Nevertheless, despite the numerous efforts against adwares, they continue to plague web surfers with their showy ads and banners as well as the nasty programs they introduce into the computer system. As the sage of the annoying adware continues, web surfers are also equipped with the best tools and utilities to combat them.

A Few Common Computer Errors



Computer errors can pop up when least expected, they can cause the entire system to suddenly shut down, and they can inadvertently corrupt data to the point where it can't be deciphered. Although they can't always be avoided, it's important to remember that computer errors can be corrected. The key is to understand what computer errors are, understand what they mean when they show up, and understand how to minimize their occurrence in the first place.

Basically, computer errors are the result of a number of things that may or may not have anything to do with the way the computer is used. They "operate" whenever there's a conflict among commands. Remember that computers essentially run off of a series of commands and it's usually a smooth process. But when one command conflicts with another command - or when one command asks for a process or information that isn't available, the computer returns results that aren't useable. That's an error.

A prime example of this kind of error is when users attempt to use software that isn't applicable for their system. Almost all software accompanies a list of system requirements which dictates what a computer needs to have in order for the software to work properly. To minimize errors of this sort, always verify that your computer has the required components. 

Insufficient memory will cause errors as well. That's why software programs include minimum memory requirements. In these situations, problems occur the moment that a piece of software attempts to access the things (hardware, memory, space, resolution, etc.) that it cannot find.

Because some programs share common files, errors can also occur when these shared files are not up to date. For instance, let's say that Program A is already installed on a computer and it's working just fine. Then let's say that the user of that computer downloads and installs Program B. Program B uses a file that Program A installed much earlier, but when Program B is run, errors popup. Those errors are the result of Program B attempting to use an outdated (shared) file that was installed by Program A. In order to fix that problem, the user would have to download an updated version of the shared file (which to say the least - is not an easy thing to find or do).

Sometimes, errors occur because a system doesn't have the required drivers or the drivers that are on the system are the incorrect version. Both errors in these cases can be resolved by updating the computer on a regular basis. Microsoft provides a section on its website that can automatically update a computer online and it does this at no cost in an effort to reduce errors like this. Always try to keep your computer updated so that should a program share a file, it will share a file that has been updated on hundreds of thousands of computers, like yours.

This article doesn't even begin to cover the entire gamut of computer errors - but additional information regarding how to get help with a computer issue (including computer errors) can be found in our article titled, "Computer Help" no matter what the problem is.

Zombie Computers Roam The Internet


Spyware and viruses are so common that you would be hard pressed to find anyone that isn’t aware of them. Under the umbrella term Malware, these little programs have been causing trouble for computer users for many years, and they seem to get more powerful everyday. A new incarnation of malware is becoming very common as of late, and it involves using a virus or trojan horse to place a computer under the remote control of a hacker. The controlled computer is referred to as a zombie and it is used to commit various dastardly deeds without the knowledge of the computer owner.

Zombie computers are almost always attached to the Internet via a broadband connection such as DSL or Satellite Internet. This is important as spammers have found that by using zombie computers to send out their junk mail they can easily avoid detection. As of 2005 it was estimated that up to 80% of all spam was sent via zombie computers, and that number is on the rise.

The increase can be attributed to smarter hackers and better technology, but the real driving causes behind the increased zombie trend are better spam filters and anti-spam laws. According to Tom Spring at PC World Magazine, “spammers are hiring virus writers and hackers to help them create armies of zombie PCs to send spam.” This union of hackers and spammers has been beneficial to both parties in opening new revenue steams that are extremely difficult to shut down.

Gregg Mastoras, a senior security analyst at the security firm Sophos says, “A new underground economy is evolving." This new economy is for the most part illegal and to date impossible to stop completely.

As of late the Chinese hackers have thrown their hat into the game and have taken the zombie computer business to the next level. Senior Pentagon Advisor Paul Strassmann recently said, “As of September 14th 2010 there were exactly 735,598 computers in the United States infested with Chinese zombies”.

Large groups of zombie computers can be used to form a “botnet” or network of slave computers. This network can be used to send out millions of spam mails in a short period of time. Slave networks are also used to commit a DoS attack. DoS attacks, or Denial of Service, target a particular website and overwhelm the server with information requests until the server can no longer handle the load. These attacks or in no way secretive, and once discovered are easily shut down. There will be a period of time however when site traffic will be disrupted by the DoS attack. Larger more sophisticated networks such as those used by governments or large firms have defensive measures in place to prevent damage from a DoS attack.

Viruses


What They Are And One Reason Why People Make Them

Over recent years, computers have become synonymous with viruses and viruses don't show any signs of disappearing any time soon. In recent news, LiveScience.com reported that "Before the month is even done, April has set a record for virus e-mails."1 In the past, we would be comfortable in telling new computer users not to worry about viruses and that catching a computer virus is rare. Today, that would be some of the worst advice we could give anyone. As reported in countless news reports, computer viruses are rampant and they're extremely worrisome. This article will describe what viruses are and then point you in the direction of some rather unique protection and prevention.

In short, a computer virus is a software program designed to destroy or steal data. It attacks computers via distribution - often unknowingly - through email attachments, software downloads, and even some types of advanced web scripting. Viruses that destroy data are known as Trojan horses, viruses that explode their attacks are called bombs, and viruses that duplicate themselves are called worms. Some viruses are a combination of each, however they can be further identified according to where they're located on a computer.

A virus originating from the boot sector of a computer is a boot-sector virus and this nasty devil does its dirty work the moment a computer is turned on. A virus that attaches itself to (infects) other programs is a file virus and activates the moment that an infected program starts. File viruses may also be referred to as parasitic viruses, however should a virus work from both the boot-sector and from an infected program, the virus is then known as a multipartite virus.

Why viruses exist remains a mystery, however we had privy access to the mind behind a virus programmer who explained his motivation behind his destructive inclinations. Apparently, this person had a deep grudge against a popular online service which shall remain unnamed. In this hacker's mind, the online service failed to do a quality job in protecting children from online smut and as retaliation, he created and distributed a virus to as many file libraries of this service as he could. His intentions were to disable the computers of the online service's users so much that they wouldn't be able to connect for days. In his mind, the loss of connection meant loss of revenue for the online service.

Although the malicious code that this person generated may have worked for a small percentage of users, sufficed to say, the online service continued on and still exists today. Despite his motivation or intention, his efforts were null.

We wouldn't be surprised to learn if other motivations behind spreading viruses were similar to this person's, but that doesn't justify the damage that viruses do. Innocent people become pawns for the evil plans of others who've convinced themselves they're doing the "right" thing.

To protect a computer from getting a virus, or clean a virus from a computer system once infected requires the use of an antivirus utility. But may be something else we can do. Perhaps we could make an effort to educate the people who want put viruses into the public about ways to display dissatisfaction with a service or product that don't involve harming innocent parties. In doing so, we just might reduce the number of virus news stories and protect our own investments at the same time.
