Examples Of Computer Virus

Monday, January 23rd, 2012

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 tries to download files from a remote source. It will introduce a .dll file into the EXPLORER.EXE process causing system instability.

Virus: W32.Beagle.CO@mm: A mass-mailing worm that reduces security settings. It can delete security-related registry sub keys and may prevent access 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 spreads by emailing itself to addresses harvested 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 constantly in the background, providing a backdoor server which allows a distant hacker to gain admittance and control over your computer via IRC channels. This virus propagates by sending itself to email attachments harvested 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 manipulated through the Internet Relay Chat (IRC) network. Furthermore, they can spread themselves via email and by 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 generate a quantity of files in the Windows system folder with filenames made up 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. Jun. 2004, P?cs (SNAF Team)?

How To Recover Computer Data

Friday, December 16th, 2011

If you make your money by using a computer, you ought to protect yourself against all computer disasters. If you were a taxi driver, you would take out car and public liability insurance. If you were an employer, you might take out plant and tools insurance. If you were a landlord you would take out property insurance and loss of income insurance.

But what do you do if you work on line? Well, if you work with computers, data is your most valuable resource, but you cannot insure against losing it because you cannot prove that you ever had it. So, what can you do? The solution is that you need to have reliable backups and several of them.

The problem is that computers do not frequently break down so we are lulled into the false feeling of security that we can make backups tomorrow instead of right now. However, the longer that you work with IT, the more you comprehend that there are no warning signs when you are about to lose all your data, which may be your entire income stream.

For example, say you make web sites for a living and update them frequently so that the search engines find them interesting. What would occur if your hard drive crashed or if they were destroyed by a virus? You might say that you would download them from your Internet host and begin again, but that is not possible, because most HTML editors will not decompile a completed website.

That would mean that you could never update those web sites again, so they would become less and less interesting to the search engines, so your ranking would fall and your earnings would plunge. And why? Because you failed to insure your business by taking adequate backups. You failed to make proviso for data recovery in the event of data loss.

However, no matter how often you backup your data on physical media, you will always be facing a risk because anything physical, any device is subject to failure and deterioration. CD’s do not last as long as we were promised. I have lost tons of data that I thought was safe on CD’s and hard drives are prone to fail with no notice whatsoever.

Even if you do overcome these issues of storage, what occurs if there is a fire or a thief really steals all your disks and computers? Your hardware would be insured but your livelihood, your data would be gone forever. All that hard effort. Your source of earnings. Gone. Forever.

There is a different alternative and that is not to hold your data on your computer, in your office or anywhere within a thousand miles of yourself. This is called cloud storage or cloud data storage. Microsoft calls it Sky Drive and offers 25 GB of free, password-protected, storage available from anywhere in the world. This kind of storage is the ultimate in secure storage providing the best value recovery planning for computer data.

How To Protect Your Computer With Antivirus Software

Friday, December 16th, 2011

Computers run so much of our lives these days. They run our payroll, our bank account, our school and business records, our governments and, for many individuals, our entertainment, so anything that disrupts computers has the potential to completely screw up our lives in the short term.

This state of affairs is bad enough, but there are also people out there who get their thrills out of writing and releasing viruses to infect our computers and screw up our lives. I am not talking about criminals, we have always had to put up with them, I mean teenagers and others who compose and release viruses to damage our computers for pleasure.

These days, a lot of families are dispersed because members have travelled to other cities to study or work and sometimes this means going to other countries too. Most of these people rely on computers and the Net to stay in touch. A infection could mean the disruption of these contacts and even the obliteration of family photo albums.

You might come to the conclusion that we rely on computers too much and lots of people would agree with you, especially those who have lost crucial information to computer viruses. At worst, you could have your identity stolen and have our financial life completely disrupted, but even losing your computer for a couple of days whilst it is repaired ‘in the shop’ is bad enough.

In my case, this would mean loss of earnings, for others it may mean a violation of privacy or even theft. So, what can we do to protect ourselves?

Antivirus software is the solution.

Antivirus software used to mean a program to scan files coming into your computer, but nowadays it means much more. Decent AV software will now include a firewall to protect your computer from being hacked and a malware scanner to stop incoming files from dropping trojans and worms etc onto your hard disk.

These small programs can read the keys that you press and send the data back to their creator. These key presses can be analyzed to disclose your preferences on search engines (in order to spam you) or your log in details to your bank (in order to steal from you).

So, you have to install either a decent antivirus software suite, which will include all of the above or you can get the components separately. Not so long ago, you would have had to purchase all these items, but now some are built into Windows. Windows now comes with a firewall and antivirus software, which will also scan email.

This is good enough for most users, but if you would like to take your computer’s safety to a higher level, you should add a dedicated malware scanner, of which there are many decent free ones. If you consider that it takes too much time to run two or three separate programs and keep them up to date or if you would like a higher level of protection, you might consider buying an AV software suite.

There are plenty of good ones like Norton, Nod, Kaspersky and others which cost little more than $30 a year for absolute peace of mind.

Players In The Antivirus Industry

Tuesday, April 19th, 2011

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 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 debate concentrated on whether Microsoft would end up in a dominant position in the antivirus market by merely bundling its recently acquired software technologies up with its Windows operating systems at no charge. This is a comparable technique that has been used in other markets such as word processing and Internet browsers. In fact, this is precisely what did take place. Microsoft has come out with a free product called Microsoft Security Essentials.

It is too early for me to tell whether MS Security Essentials is a world-class antivirus product, but it is not free to everyone. Microsoft has been struggling with 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 check. (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 be able to buy 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 well-known in this market. There are many companies with great market presence in other countries that are starting to become more widely known. 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 required to discover and provide fixes for new viruses is quite astonishing. Malicious programs are getting more and more complex and the number of them is increasing.

Many companies may find themselves without the capital to equal the hard work of those truly determined to create chaos. The antivirus companies are receiving hundreds of new examples 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 intelligent enough to move around in a system by renaming themselves in an effort to make it hard to remove them.

Adware And Spyware Blockers

Sunday, June 27th, 2010

I want to tell you the story of a law school student whose thesis was about money laundering. She often used to Google the term to come up with a useful list of online references. This proved to be useful to her and the entire procedure of writing her manuscript became easier for it. After a few months, she came across several problems like being sent to a page which was totally unrelated to money laundering every time she entered that search term.

At first, she thought it was just a glitch in the Internet system and then she thought that perhaps it was a problem with the search engine she is using, but the continual recurrence of the problem, made her think that she had picked up a virus of some sort. We all can’t stand people bugging us, but people we can fend of.

What this law student was confronted with was a computer bug that she could not ward off on her own. In the first place, she was not a technologically-savvy person and in the second place she never used her laptop for anything other than scholastic research and the actual writing of her documents.

The situation above is not an unusual issue. There are many people who find themselves caught up in technological problems that are mystifying, but which can actually be described in two words: spyware and adware. The infamous term ’spyware’ was first coined in the year 1995 but it was popularized in the year 2000. Spyware is computer software smuggled into a personal computer in order to get hold of the personal information of the user.

This is done by capturing your keystrokes, web browsing history and even scanning the user?s hard drive. It may seem like something you see in James Bond movies, but that is wrong because anyone can become a target of spyware. Spyware can be utilized to spy on criminals because it is helpful to society, but how what about the use of spyware to intercept credit card details and the like?

What people can do to guard themselves is to block spyware and other software like it such as adware and malware. This can be achieved quite simply by deploying an adware and spyware blocker. The function of these blocking programs include clearing or disabling existing spyware or to inhibit the installation of these malevolent programs.

Spyware, adware and malware are not like viruses or worms which replicate themselves, but they are just as much hassle because they disrupt your computer’s behavior. One of the most common problems caused by these programs is the slowing down of the computer which is very exasperating.

In some infections, spyware is not even obvious as the cause of the problem. Therefore, it is best to have a blocker set up on your computer to avoid the infection in the first place. It is far easier to prevent than cure and it is also far better to be safe than sorry

How To Ward Off Viruses

Tuesday, June 8th, 2010

Protecting your computer from viruses is getting more and |more difficult each day. While it may sound a little paranoid, it is true that you cannot let your defense drop for one second. Even commercial giant Microsoft has found its own systems 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 eradicate 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 medium 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 intervention, and take full advantage of weaknesses within a system or program. With technology advancing everyday, and the convergence of computers with other mobile devices, the potential for new types of threats also increases.

Luckily, the advancement of antivirus software has kept pace 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 protect against the threat of a virus:

You should evaluate your current computer security system. With the threat of a new generation of viruses being able to attack in a multitude of ways, the approach of having just one type of antivirus software has become outdated. 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 comprehensive 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 infiltrate your system.

You should install antivirus software created by a well-known, reputable company, because new viruses erupt daily, so it is vital that you update your antivirus software daily. Become familiar with the software’s real-time scan feature and configure it to start automatically every time you boot 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 sources 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 may be the only way to retrieve your data if you computer becomes infected.

There are numerous applications available to consumers, so with a little research, you should be able to pick the program that is right for you. Many programs provide 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.

Anti-Virus Software

Thursday, January 14th, 2010

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

It is more difficult to clear viruses from your cell phone as well, because there are less vendors for the anti-virus software and cell phone users are often less technologically knowledgeable than computer users, although the technique of clearing the virus is fairly 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 item of software. It does not matter what you use the Internet for - transferring data back to base or receiving emails from friends - you are subject to attack.

For instance, if you use the Internet only to communicate with your head office, a hacker could try to piggy-back your link to gain access to the mainframe at head office and possibly access financial or other personal data and if you just send to and receive emails from your friends and family, you are open to attack from malicious fools around the globe.

If you use webmail such as that provided 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 obtain your email via an email client such as Outlook or Outlook Express, then you do not even have that small amount of security.

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

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

However, be cautious with the free anti-virus software, because not all of it is effective enough. The exceptions that spring readily to mind are Avira and AVG. These are excellent items and have rightly achieved worldwide acclaim. Just Google the two names to get the download address.

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.

Once you have selected 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 be concerned, the default settings are fine for the overwhelming majority of users. The only choice you will get that it is vital you make correctly is to allow automatic updates.

New viruses are being discovered or fixed every day and for your anti-virus software to be effective, you must permit it to bring itself up to date whenever it wishes to.

Adware, Spyware and Anti-virus

Saturday, December 26th, 2009

Adware, spyware and anti-virus software share some similarities, one of which is that all three are major problems 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 avoided. 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 information for advertising and marketing purposes. They also sell the information to advertisers and other parties.

Adware, on the other hand, is a more legitimate type 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 types of adware, on the other hand, download advertising content when a particular application is being run. Some adware acts like spyware in that it tracks and reports user information to the program’s authors.

The signs of spyware infection include pop-up ads that seem to be irrelevant 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 destructive kind of software. They were designed and created for one purpose alone and that is to cause mayhem on your computer. They may destroy whatever data they come in contact with, can initiate 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 offers spyware and adware scanning and removal utilities. They then remove it as well as its components located in the system registry and other places 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 might 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 reduce the risk of computer infection and guarantee the security of all your computer records.
