Anti-Virus software is a program to run on your computer, often in the background and keeps malicious spyware and background viruses from attacking your hard drive.there are different techniques that the software will use to keep viruses off of your computer. The software will start to scan all your files you have saved so that it can search for known viruses that will match definitions in a dictionary made only to detect a virus. Having antivirus software protects your computer from getting infected from different kinds of Mal ware that can be embedded in e-mails, downloads, and even programs that you install your computer.

The software will identify suspicious behavior from any computer program that might show signs of infection. The analysis may also include data captures,port monitoring and other methods. Most commercial antivirus software starts off with the approach called the virus dictionary approach.

Basically what happens is your antivirus software is constantly updated with a latest in the dictionary that it carries of viruses. The software scans your computer looking for anything that matches the different files that it has in its list of different viruses. Once the computer software comes up against any of these files that match in its list or dictionary of viruses, the first thing it does is try to remove it from the file. If you cannot remove it from the file, it will quarantine it. By putting the virus in quarantine, it prevents it from spreading further onto your computer.

Because the virus dictionary approach relies on a file of viruses, you need to make sure that when you buy antivirus software it comes with unlimited virus updates. The world of spyware, viruses, and Mal ware is ever changing and evolving and it is up to a good software company to keep up to date with the different viruses that are out there. Most software will update itself with the latest viruses. But you need to make sure that you are updating frequently because once you stop, the odds are that a new virus out there can get on your computer.

Most versions of antivirus software now continue to run in the background of your computer. Especially if you are constantly online, you can get a virus just by visiting a webpage. There are computer hackers out there that can install a virus into your computer from the webpage you are visiting. With the current antivirus software that is out there, if it’s running in the background it will catch the attempt to install the virus, remove it, or quarantine it.

You can buy antivirus software, or you can actually download free versions off of the Internet. Now this may sound funny because downloading something off of the Internet could have a virus on it, but there are websites that have high authority and are trusted to provide freeware that is constantly updated. If your computer is new, you may actually are ready have antivirus software preloaded in the operating system.

Before we discuss antivirus software it is important to understand what a virus is. A virus basically comprises a small program, a macro or a script designed to interfere with the normal functioning of a computer in various ways. At the grass root level these mischievous entities gain entry into our computers through external storage devices such as floppies, compact discs etc. However, with the advent of the internet, viruses now have a much easier way to infiltrate our PCs. All that the warped mind of a virus programmer has to do now is write the necessary code and introduce it into the internet system via an e-mail or other web enabled procedure. The online network means the virus can infiltrate literally billions of PCs in a short period of time. Days, or perhaps weeks later, the virus gets identified and a battery of coders or software professionals get down to building the vaccine to quell the code. Another change to the virus landscape is that they are now largely used to profit financially by stealing valuable information whereas before maximum disruption was the aim.

Pleasure of proving someone wrong

Software companies often come out with inflated claims about the security of their latest creations which exaggerations of virus proof protection all to common. They claim that it is impregnable and that users will enjoy an uninterrupted experience when using the software. This is what generally kicks off the war. World over, there are people, mostly teenagers and those in their twenties who fancy breaking into the secure environment created by the big players in the software industry. They may not do this for any monetary gains, but to derive pleasure from being able to unsettle the claims made by the big names.

Best antivirus downloads. Are free ones ok?
In order to combat viruses it has now become necessary for PCs users to protect themselves and not rely on their operating system and software to do it all. In response to this need there is naturally a large number of anti virus downloads available on the internet; some are good, some are bad and some will do you more harm than the original virus. You will also need to decide if you need to buy antivirus software or just get a free version.

Like with most things, those that charge a fee are usually better although this is not always the case. However, it is worth noting that a major impediment with several free downloads is that many of them do not have an uninstall facility. This means that once you have chosen to install the free anti virus program and you will find it difficult to migrate to another version later. You will either have to leave both on your hard drive or reformat your hard disk.

Another important factor is the lack of continuing support from the free providers, particularly regular updates. Viruses keep sprouting every second and if the provider does not update the software for the new viruses almost on daily basis, your computer security may be compromised. You should consider these two points carefully before deciding you want to save a bit of money and opt for the free versions.

Computers have become so important in so many parts of our personal and professional life that it is very important to safeguard the data stored in them against viruses which are designed to destroy or steal it.

However, many people take this very lightly and never think twice about the damage that can be caused by such viruses. Others may consider antivirus software but then opt for a free version rather than paying for it. What they do not realize is that even these free antivirus downloads might be spam or can inject virus into the system.

The free versions that are not malicious in their intent may however be very ineffective in detecting and destroying viruses. Much antivirus freeware is outdated and not powerful enough to fight the virus or remove it fully from the system.

Keeping this in mind many software companies are trying to cash in on the demand for a good antivirus software. So they introduce antivirus software which is powerful enough to fight any form of virus and it also provided one year free upgrade after which time the user can update the virus for a small additional fee. This software is normally moderately priced ($25 – $65) and can provide a complete solution for your systems security and safeguard the data from virus threats.

When you become a paid customer of an antivirus program you are entitled to certain special benefits which you are devoid of when you download free antivirus software. You will need to pay for customer support, possible after a short period of free support, but the most serious disadvantage is that the software is not automatically updated regularly. This prevents it being effective against new viruses which come on coming day after day.

Whereas when you buy antivirus software the software company is responsible for all your queries related to the software and its functioning. As the competition among the antivirus software companies increases more are offering increasing functionality (i.e. antiadware, privacy features etc) and better value. Free 24/7 live support is also becoming offered by some of the big players. Moreover the software that you buy will entitle you for a free upgrades for at least one year and after that you need to pay only a small fee to upgrade and continue using the software.

Therefore many benefits are experienced when a user opts for a paid antivirus software. Now, this may come as no surprise but it is all too common for people to pay more in the long term by taking the cheap short term option.

Before purchasing of downloading antivirus software there are some features that should look out for. We believe the key factors determining the quality of antivirus software is:

1. Its effectiveness at removing viruses (check independent tests for unbiased results)
2. Its ease of use (normally down to its user interface)
3. Its value for money
4. Its customer and technical support (should be free and 24/7 ideally)
5. Its regularity of updates
6. Its drain on system resources
7. Its compatibility

When all the major criteria were investigated we found that Kaspersky antivirus 7.0 to be the best all round antivirus software on the market day. However, it may not meet your requirements so it is important to do your own investigation using the criteria above. Our findings of some of the top sellers are below. Hopefully this will give you some guidance of what is out there at the moment and what may suit you.

Kaspersky Anti-Virus 7.0
The virus detection technology that drives this software has performed very well in independent tests and gained a strong reputation within the industry. The technical support is excellent and the user interface intuitive.

The other main advantages with it are the parental control features which are not present in other software (great for you parents out there) and the password protected privacy control. We found that it had minimal effect on PC performance (apart from the first scan which did slow things down). Finally, and very importantly it carried out automated hourly updates and real time internet scanning.

The downsides were its price $59.99 and the time it took to do the initial scan.

BitDefender Antivirus 2008
Another very effective piece of antivirus software is BitDefender. its scanning engines are ICSA Labs certifies and it also adds the added bonus of antispyware and antiadware. Gamers should be pleased with the new gamer version which stops annoying pop ups during game play.

A key advantage of this software over others is the rootkit detection and removal feature. Again this is something that sets it over and above the competition. Free 24/7 support and a reasonable price ($24.95) make it a real contender to Kaspersky antvirus 7.0. The downsides to this version are the lack of advanced configuration options which will frustrate the more advanced user. The scans were also on the lengthy side.

Norton Antivirus 2008
Despite having a strong brand and many years of experience developing antivirus software we think Norton Antivirus 2008 to be one of the worst on the market. It does the basics ok but there are too many problems with it to be competitive. For example, there seems to be an assumption only IE users exist. Help terms are geared towards IE users and Browser Defender does not work with any other browsers.

It is a massive 300MB, that is nearly 6 times the size of Kaspersky anti-virus 7.0. The limited performance does not justify this size. It slowed down our machine measurably. The interface was awful and configuring settings was a real pain. Finally, the anti-spyware was not very effective.

These are just three of the big players. Please do your research as the best known are not always the best.

Adware is as annoying as spyware for computer users. What is adware? Adware stands for advertising supported software, it is a software that can automatically play, displays, or downloads ads to your computer after a software has been installed that contains the adware, or even when you are using that specific downloaded application. Certain adware as a matter of fact can be classified as spyware, because it is privacy invasive software.

How does Adware work? Well the advertising functions are built into or perhaps bundled with another software, this software will mark or make notes as to what internet sites you have gone too, and it will go off of this information to pop up advertisements on your computer that match the sites you have visited.

Why do people create Adware? Well sometimes the developer of the software will put in the adware because it is a way to allow him or her to recover the cost of developing the software. At times this may also allow the developer to offer their software for free or a reduced price.

In fact at times the income the developer earns off of these ads may motivate them to create more software with the adware bundled in, or upgrade the current software. Of course when these advertisements pop up on your computer you’re not thinking of the money the developer made, you just thinking how annoying these interruptions are to your work or fun.

Adware can also be known as shareware, although there are shareware that does not have adware bundled with it. The shareware that is advertising supported is adware, while a shareware program that is not supported by ads is just normal shareware. At times a way for the developers to make more money they will offer a registered copy of the shareware and it will promise no advertisements.

Just a few samples of some of the better known programs that have adware bundled with the downloads are as follows:

Adobe Reader
Kazaa
AOL Instant Messenger
Yahoo Messenger
Bonzi buddy
Messenger Plus! Live
Smiley Central
Burn4Free
Comet Cursor
RealPlayer
Gator
Hotbar
Incredimail
WeatherBug
Windows Live Messenger
Zwinky

This is only a partial list of programs, but you can tell some of the more popular downloads have adware bundled with them. So basically be careful at what you download or get an adware remover. I found it amazing that some of these had adware attached to them, while others had messed with my old computer so I had a feeling that something was wrong with the download.

How many people have Yahoo messenger though? Millions if not billions of people, and I bet none of them was aware of the adware being bundled with it. Same with AOL Messenger, again billions have this program downloaded onto their computer, where they aware of the adware?

The biggest surprise I felt was Adobe Reader, I really wouldn’t have guessed that being bundled with adware. It just goes to show you, you truly never know what all you are downloading.

As far as removing adware, there are several programs that will detect and remove adware. In fact some of these choices have the option of removing both adware and spyware. Two horrible things that you can remove at once that is great!

The Internet is a fantastic tool and is open to absolutely everyone. Unfortunately, some people are not aware of the dangers that exist. You should be made aware of these and learn how to best protect yourself. There are a number of ways to do this:

1) Make sure your Windows Firewall is switched on
2) Make sure you have a good antivirus package installed on your computer and that you regularly update it
3) Never open links from emails if you are unclear about its origin
4) Only download files from trusted websites
5) Only use a credit or debit card online with trusted providers i.e. ClickBank, PayPal etc

These basic points may seem like common sense, but you’d be surprised at how many people make these mistakes. What follows could be a virus infection on their computer, credit card fraud, and a whole host of other problems.

The Internet is a useful tool but has too many problems and dangers. So what else can be done to minimise any risks? Well next time you plan to surf the net, why not use a proxy website? There are loads of proxy sites available on the net, mostly free, so you shouldn’t have a problem finding one.

Proxies act as a middle man between your computer and the Internet. It routes data to you and handles all requests you make on your behalf. This way, when you visit websites, your details like your IP address and other information isn’t disclosed to the website you’re visiting. Instead, they capture the proxy’s details. This is useful if you want to retain a degree on anonymity while you are surfing and also gives you an added layer of protection from virus threats and hackers.

My proxy website is sometimes called Ninja Proxy or Secret Proxy. It has been around for a while now and is getting increasingly popular. All you have to do is visit the address or if you type in Ninja Proxy in Google it should come up. When you are at the site scroll down and locate the URL bar. You will see the http in the box indicating the place of the web address. Once you have entered in all you have to do is hit the GO button and you’re away!

Congratulations, you are now surfing behind an anonymous proxy website and your personal details are safe.

This is just one example of a proxy website that exists online. There are literally thousands of them out there. Another step you might want to take to protect yourself while online is to use an encrypted tunnel. These are particularly useful, especially if you are dealing with sensitive matters like large volume credit card transactions or Internet banking. The way it works is by creating a virtual tunnel between your computer and the server that provides the proxy and encryption services.

All of the data between you and the server and jumbled up. This is the purpose of encryption. This way, if somebody were to intercept and data, all they would get if jumbled up data and not the actual data itself. This would ensure maximum protection and should definitely be thought of seriously if you use a wireless Internet connection. There are numerous software packages available on the Internet that a hacker could purchase.

He could then download it and use it to hack your Internet connection from his computer. He could then steal you bandwidth, download illegal material, and even spy on your surfing habits. This is not meant to scare you but just to make you are of all potential dangers that exist while you are surfing online.

Unfortunately, encryption servers are not free and you will have to pay for it. It is definitely worth the money though and the level of protection you get from it is well worth it.

I hope you find this article useful and that you can use the tips and suggestions outlined to increase your safety and privacy while you surf online. Happy surfing!

We all know that computer viruses exist and have heard the many horror tales of how they can take out thousands of computers in one shot. Unfortunately for those whose computer has been damaged by a computer virus, these tales are not only true, but very destructive and time-consuming. However, even if you know how to protect your computer from one of these malicious viruses, there are other malware programs that can be almost as damaging and is far more common. The culprits are called spyware and adware.

These irritating programs can interfere with your computer every time you jump online. Adware is more or less harmless when settled onto your computer by itself. Mostly it simply generates a lot of spam (unsolicited and unwanted email) for products that bring advertising directly to your email. Adware can also produce “popup” ads on your computer.

Spyware, however, is much more threatening and dangerous to your computer. Spyware not only floods you with advertisements, but it also accesses information on your computer and delivers it to other companies and potentially dangerous people. Additionally, spyware can change your entire computer through PC configurations which open you up to a world of trouble. Spyware is utilized by unscrupulous people as one of the main means of identity theft because it fishes information from your computer and can “learn” about almost anything you do on the Internet, then report back to the originator.

There are numerous methods for ridding your computer of spyware, but the most effective is learning to avoid it in the first place. You can begin this process by adjusting your computer settings appropriately. Depending on your operating system, you may need to do some informal reading of your system’s help files. You should find your Internet connectivity options and then look for a tab that refers to the security of your computer system. You should always adjust this to at least Medium security, or Medium-High. If you change it to High security, that setting might actually prevent you from accessing web sites that you need; so Medium is normally recommended.

You also need to ensure you have a firewall in place on your computer. A firewall is sofrware that can be configured to automatically block out unidentified programs which attempt to gain uninvited access to your computer. The parameters of your firewall are easy to set, and by doing so you allow certain programs in while keeping harmful (or questionable) ones out. Given most people’s lack of knowledge about programs that need to run on a computer, a firewall will sometimes try to block program resources that are indeed harmless. That, however, it is a small inconvenience for keeping your computer and information safe from intruders.

Lastly you certainly will need an anti-spyware program running on your computer’s background. This helpful software can be downloaded from an Internet merchant or purchased at any store selling computer software. You need a program that can detect and intercept spyware as it attempts to invade your computer; it should also have the ability to scan your computer for existing spyware and isolate it. Make sure to keep your anti-spyware program up-to-date with new daily or weekly “definition” files so that it works effectively. You never want to leave your computer unprotected and open to spyware or adware.

Most of us rely on our personal computers and those in our office to complete multiple tasks each day. If that data is lost or compromised it can create numerous problems for us. Protecting computers against viruses and spyware is something you should do before you start using any program on it. The information you prevent from being accessed could be your credit card accounts and bank accounts. If they are compromised you can end up becoming a victim of identity theft.

One way that people accidentally end up with viruses or spyware on their computer is by not paying attention to the sites they use. Dont get into the habit of giving out your personal information online just because a site asks for it. To opt in, you should only have to give them a first name and an email address.

Always check the address in the URL to make sure you are accessing a secure site. It should start with https as this will let you know it is very secure. If it only starts with http then the site is not secure and you can end up compromising the security of your computer if you continue entering information on the site.

Viruses can spread very rapidly so if you think your computer may be infected, you should take care not to pass it to any other area of your computer or to others via email. By disconnecting your computer from the network you have a good chance of isolating the damages.

Always be on the alert for various types of emails known as phishing. This is a scam to get you to provide personal information. Once you do, spyware can be attached to your computer. Never respond to emails asking you for personal information as most credible companies wont contact you for such information.

Make sure you purchase a virus and spyware protection program that is very easy to install. Most of them offer step by step instructions for you to follow. You can find out how easy such software programs are to install before you buy them just by reading some independent reviews online.

You need to choose the program for your computer protection very carefully. While they are designed to give you the very best security, you can be sure those trying to pass viruses or get spyware into your system are very smart. They have learned elaborate tricks to be able to gain access to your information.

One of the latest tactics that these criminals have been using is to sell software that is supposed to protect your computer from viruses and spyware. Unfortunately, what they are selling you is actually the very thing you are trying to protect yourself against. Always get such software from a company that has an excellent reputation, not just any one that you come across online for a good price.

In order to ensure your computer is well protected against viruses and spyware, you want a program that offers you instant updates. These will usually happen for one full year after you install the program. This ensures that your protective software is always the most current available and criminals will have a hard time infecting your computer system with viruses or spyware.

Different approaches are followed by different types of antivirus software downloads to identify and destroy the viruses in individual PCs. The two most popular approaches are the database or dictionary scanning and suspicious behavior scanning. In the first approach new files are matched with virus affected files installed. And in the second approach the program file is monitored for a pattern, which generally turns out to be a virus. I am going to discuss both in this article and then go on to describe some less obvious methods.

Database scanning

Database or dictionary scanning involves an antivirus application comparing files with already known viruses to find a code match. The antivirus software has a database of known viruses which should be updated on a regular basis to keep on to of virus changes. Any infected files are then either quarantined as the software tries to recover the infected file or they are deleted altogether. To keep up with the work of identifying newer viruses spread the antivirus download software should be updated one a day or at least one a week. It is imperative that the antivirus software is upgraded regularly to keep up with the newer and more malicious viruses that might attack the system. The database of known viruses is expanding rapidly and automatic communication between locally installed software and the database network means the global sharing of information.

The antivirus software assists the operating system and safeguards files when they opened, closed or mailed. Every attachment is checked before opening and every file is scanned before being uploaded or downloaded into the system. But this approach is only suitable for known viruses but it can not cope with polymorphic viruses which are capable of masking the code in a cryptic form. Hence is left undetected and the virus never shows up in a scan. However, another methodology used by good antivirus software may be able to detect it. This is described below.

Suspicious behavior scanning

As the name suggests this also involves the antivirus program monitoring every single file for viruses. However, unlike the previous method which matched viruses against those in a database, this process involves flagging files whose code or behavior has altered in some way. If it find any irregularities with any file it immediately gives out a warning message to the user. This approach can identify new viruses or any possible future virus attacks. But the program becomes desensitized to false warnings when the user starts clicking on every false positive message.

Sand box detection

In this approach the sand box mimics the operating system and running executable files within it. Files are then examined and any infections analyzed. Therefore, virus detection can take place in a controlled environment with infecting the operating system. This approach is used as on demand scans.

Think you don’t have virus on your PC? Are you sure? Many viruses are designed to work quietly in the background collecting valuable information about you. They are not designed to get noticed so it is imperative that you run regular virus scans on your PC.

If your work involves computers and particularly the use of the internet, computer viruses are part of your life unfortunately. They come unannounced and you or your software busy from time to time. The nuisance value and at times even the financial losses it causes are only well known by many people. There are several anti virus programs available from the internet.

Most users who need to access the internet on continuous basis would have installed some decent anti virus programs which run automated scanning at periodic intervals. The scanning process may take a few minutes but it is well worth the trouble. Every person who uses a computer on continuous basis will need short breaks. The ideal thing to do would be to schedule the scanning during these breaks so that you do not have to spend idle minutes before the monitor. Check the scan results and look at the prompts for action if needed. This measure when properly implemented will normally help you to maintain your computer in good health for a long time.

Even when you are able to go through several weeks without any virus problems and your computer is doing exactly what it is supposed to, it would be worth while to conduct a scan as many viruses and other forms of malware work quietly in the background collecting data. and corrupting files you may not use often.

Some measures for a healthy computer

A reliable antivirus must be installed and kept running at all times. If your license code need validation, do not delay the process and get it on the day you are notified. An active firewall should be in position every time you open the internet. Most of the reputed vendors of anti virus programs provide regular updates, but you should allow installation by clicking the relevant button. The browser security should be maintained at maximum levels at all times. If you are asked by the browser to permit installation or opening some content unfamiliar to you, deny permission.

To enhance protection levels choose an anti spyware program (either as a bundle with your antivirus software or as separate piece of software).

Be very careful about e-mail attachments, they are the major source of viruses.

Also be wary of search bars and browser bars which are often used by by several scam artists.

Look for the authenticity of the offer and check back with your provider if need be.

Use a different credit card for your online transactions to ensure financial security as well as computer security. Credit card details are one of the main targets for the creators of computer viruses.

Run a virus scan at least once every week.
