Most computer users 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 aspirations to become a key player in this enormous growth industry.

In fact, Microsoft acquired intellectual property and technology rights from GeCad software in 2003, a company based in Bucharest, Romania. They also purchased Pelican Software, which had a behaviour orientated 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 debate centered on whether Microsoft would end up in a dominant place in the antivirus market by simply bundling its newly acquired software technologies up with its Windows operating systems at no cost. 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 happen. 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 scarcely 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 be able to buy a computer and the last thing they care 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 capital to match the hard work of those truly determined to create mayhem. The antivirus companies are getting hundreds of new samples of viruses a day! What is more, the new viruses are getting “cleverer” in that they spread 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 difficult to remove them.

Adware, spyware and anti-virus software share some similarities, one of which is that all three are major nuisances for computer users. Let’s make a distinction between the three.

Spyware is software that does not necessarily harm your computer. What it does is build links whereby someone else apart from the computer owner can communicate from that computer. Normally spyware records the different kinds of web sites you go to and sends that information to web advertisers, who then later send you unwanted emails and pop-ups.

Which is why spyware is unpopular and shunned. It is more intrusive than adware. Spyware has its own separate executable programs, which allow it to record your keystrokes, scan files on your hard disks and look at other applications that you use, including but not limited to chat programs, cookies and Web browser settings.

Spyware then sends the information that it had gathered to the spyware author. The author will then use this data for advertising and marketing purposes. They also sell the information to advertisers and other parties.

Adware, on the other hand, is a more legitimate form of software.. It is similar to spyware but adware is advertising spyware which is bundled into free software or a free program and is installed automatically once that particular program or software is loaded into your computer system.

Some forms of adware, on the other hand, download advertising content when a particular application is being run. Some adware behaves like spyware in that it tracks and reports user data to the program’s writers.

The signs of spyware infection include pop-up ads that seem to be unrelated to the site you are looking at. Sometimes spyware pop-ups are advertisements about adult contents. Furthermore, if you become aware of your computer slowing down, there is a big chance that spyware and its components have found their way into your operating system. If Windows desktop takes a long time to load, it is best to scan your computer for spyware infections.

Viruses, on the other hand, are a harmful kind of software. They were designed and created for one reason alone and that is to inflict chaos on your computer. They may destroy whatever data they come in contact with, can instigate self replication and then infect as many components of the computer’s operating system or network as possible.

These days, a lot of anti-virus software also provides spyware and adware scanning and removal utilities. They then remove it as well as its components located in the system registry and other locations on your computer. It is therefore, good practice to regularly update your anti-virus and anti-spyware scanner to ensure that your computer is protected from the thousands of spyware and viruses in the Internet. Beware of free add-ons or free anything really.

Adware could be spyware in disguise and could be just waiting to be deployed for its writers to gather your information. Learn how to set up a firewall and pop-up blocker in order to minimize the risk of computer infection and ensure the security of all your computer files.

New computer viruses are being generated, exposed and fought every day. These computer viruses are created often just to annoy us and to inflict chaos in our computer systems. Hereunder, I have described ten viruses recently cited as being the most prevalent and being potentially able to cause the most harm. However, new viruses are being developed daily, so this list is by no means complete. The only thing you can do is remain alert, keep your anti-virus software updated, and keep aware of the current computer virus threats.

Virus: Trojan.Lodear: A Trojan (from Trojan Horse) that attempts to download files from a remote source. It will inject a .dll file into the EXPLORER.EXE process causing system instability.

Virus: W32.Beagle.CO@mm: A mass-mailing worm that lowers security settings. It can delete security-related registry sub keys and may prevent admittance to security-related websites.

Virus: Backdoor.Zagaban: A Trojan that allows the infected computer to be operated as a covert proxy and which may degrade network performance.

Virus: W32/Netsky-P: A mass-mailing worm which propagates by emailing itself to addresses produced from files on the local drives.

Virus: W32/Mytob-GH: A mass-mailing worm and IRC backdoor Trojan for the Windows platform. Messages sent by this worm will have the subject chosen randomly from a list including titles such as: Notice of account limitation, Email Account Suspension, Security measures, Members Support, Important Notification.

Virus: W32/Mytob-EX: A mass-mailing worm and IRC backdoor Trojan similar in nature to W32-Mytob-GH. W32/Mytob- EX runs continuously in the background, providing a backdoor server which allows a remote hacker to gain admittance and control over your computer via IRC channels. This virus spreads by sending itself to email attachments gleaned from your email address book.

Virus: W32/Mytob-AS, Mytob-BE, Mytob-C, and Mytob-ER: This family of worm variations possesses similar characteristics in terms of what they are able to do. They are mass-mailing worms with backdoor functionality that can be controlled through the Internet Relay Chat (IRC) network. Furthermore, they can propagate themselves through email and through various operating system vulnerabilities such as the LSASS (MS04-011).

Virus: Zafi-D: A mass-mailing worm and a peer-to-peer worm which copies itself to the Windows system folder with the filename Norton Update.exe. It can then create a number of files in the Windows system folder with filenames consisting of 8 random characters and a DLL extension. W32/Zafi-D replicates itself to folders with names containing words like ‘share’, ‘upload’, or ‘music’ as ‘ICQ 2005a new!.exe’ or ‘winamp 5.7 new!.exe’. W32/Zafi-D will also display a fake error message box with the caption “CRC: 04F6Bh” and the text “Error in packed file!”.

Virus: W32/Netsky-D: A mass-mailing worm with IRC backdoor functionality which can also contaminate computers vulnerable to the LSASS (MS04-011) exploit.

Virus: W32/Zafi-B: A peer-to-peer (P2P) and email worm that will reproduce itself to the Windows system folder as a randomly named EXE file. This worm will test for the presence of an Internet connection by attempting to connect to google.com or microsoft.com. A bilingual, worm with an attached Hungarian political text message box which translates to ?We demand that the government accommodates the homeless, tightens up the penal code and VOTES FOR THE DEATH PENALTY to cut down the increasing crime.

If you log on to the Internet, you definitely need anti-virus software. It does not matter whether you do not use a computer. Whatever you use to get on line you must have anti-virus software. Although there are hundreds of malicious idiots producing viruses to attack those who log on to the Internet from a computer, there is an increasing number who are focusing on mobile phone users as well.

It is more difficult to clear viruses from your cell phone too, because there are less outlets for the anti-virus software and mobile phone users are often less technologically savvy than computer users, although the method of clearing the virus is quite analogous.

Let’s just use the example of using computers to go on line. If you go on line, your ant-virus software is your most essential piece of software. It does not matter what you use the Internet for – transferring data back to base or reading emails from friends – you are subject to attack.

For example, if you use the Internet only to communicate with your head office, a hacker could try to piggy-back your connection to gain admittance to the mainframe at head office and perhaps access financial or other personal data and if you just send to and receive emails from your friends and family, you are open to assault from malevolent fools around the world.

If you use webmail such as that offered by Yahoo, Hotmail and MSN to name only the most popular, you will be protected from the most obvious attacks, but still not safe. If you receive your email via an email client such as Outlook or Outlook Express, then you do not even have that small amount of protection.

If you do not use email, but only surf the Internet for research or whatever, you are still not safe, because some websites and loaded with viruses, trojans and worms, waiting to unload them onto unwary surfers.

Therefore, whatever reason you surf the Internet for, you could do with some type of protection. Fortunately, anti-virus software for personal use is low-cost and can even be free. Business users will normally get tax relief on their purchases.

However, be cautious with the free anti-virus software, because not all of it is effectual enough. The exceptions that spring readily to mind are Avira and AVG. These are exceptional products and have justly gained worldwide praise. Just Google the two names to get the download URL.

The anti-virus software that costs something (typically $25-$50 per annum) invariably offer one to two months free examination before you buy and a reduction in price, if you pay for more than one year at a time. Names that fall into this class are Kaspersky, McAfee, Norton and Nod.

After you have chosen your software, the subsequent steps are the same for free and paid software. First install it and then configure it. If you are not certain how to do that do not worry, the default settings are fine for the vast majority of users. The only choice you will get that it is imperative you make correctly is to consent to automatic updates.

New viruses are being exposed or fixed every day and for your anti-virus software to be effective, you must permit it to update itself whenever it wants to.
