MyDoom Virus & How YOU can help!

We have been monitoring stories and technical information that
is available on this Virus that is Spreading like Wildfire! We believe
that starting Feb 1st, we may see things slow down on the net,
email problems, sites not available etc. We saw it before with
last years big virus, but sources say this new virus is the
worst one yet.

Based on their code, the Mydoom worms are scheduled to launch
denial of service attacks against the SCO Group Inc. and Microsoft
Corp., starting Feb. 1. A DOS attack means the infected computers
are set to overload both companies' web servers with bogus
information, in an attempt to prevent access by legitimate users.

Mydoom.B also prevents infected computers from accessing the web
sites of Microsoft and many anti-virus software makers, making it
difficult for the owner of an infected machine to get help.

With hundreds of thousands of infected computers as of Friday and
at the estimated rate of 12,000 per hour systems becoming infected,
this virus is taking over. It has been estimated that now 20% of all
email that is being sent/received is the Mydoom virus and its variants!
With this many systems infected and once Feb 1st hits, these infected
systems will start the DoS attacks from all over the world. How will this
affect you?

Email Service could be slowed down, pop3 errors, websites slow to bring
up or not available. Yes, this could very well affect even our sites and

your access to them when the DoS attacks start and there is NOTHING
we can do to prevent this from occurring except educate our members
and provide information on how to protect your system. This virus will
cause so much information to be passed through the nets backbones
that it will cause congestion, packet loss, instability of the major
backbones and services being temporarily denied while major ISPs
attempt to block and prevent further problems due to the DoS attacks
and this virus.

This could turn into a nightmare for many companies that do business
and depend on email, website reliability etc. HOW CAN YOU HELP?

DO NOT OPEN ATTACHMENTS - CHECK YOUR COMPUTER FOR THE VIRUS
UPDATE YOUR VIRUS PROTECTION DAILY if NECESSARY - If you do not
have an anti-virus software installed... DO SO NOW!!

There is NO reason that anyone on the internet should not have an
anti-virus software installed on their computer. The fact that many do
not and many that do not update their software regularly plus opening of

attachments when you do not know who they are from or where not
expecting it - This is what is causing the spread of these viruses like
wildfire.

MyDoom Details -

Avoid opening attachments from suspicious email messages
Emails sent out by Mydoom.B are generated randomly. The From address
may also be spoofed to appear as though the message is from a different
address.

The subject of the message will include one of the following:

Delivery Error
hello
Error
Mail Delivery System
Mail Transaction Failed
Returned mail
Server Report
Status
Unable to deliver the message


Not all email messages with these subject lines carry the MyDoom.B virus,
some may be legitimate status messages.

The message body will include one of the following:

RANDOMIZED CHARACTERS
test
The message cannot be represented in 7-bit ASCII encoding and has been
sent as a binary attachment.
sendmail daemon reported: Error #804 occurred during SMTP session. Partial
message has been received.
The message contains Unicode characters and has been sent as a binary
attachment.
The message contains MIME-encoded graphics and has been sent as a binary
attachment.
Mail transaction failed. Partial message is available.
The attachment will have one of the following filenames:

body
doc
text
document
data
file
readme
message


Attachment:

The attachment may have either one or two file extensions. If it does have two,
the first extension will be one of the following:

.htm
.txt
.doc

The second extension, or the only extension if there is only one, will be one
of the following: .pif .scr .exe .cmd .bat .zip (This is an actual .zip file that
contains a copy of the worm, sharing the same file name as the .zip. For
example, readme.zip can contain readme.exe.)

We have gathered information for you that will help you get an anti-virus software
Program, how to check for the virus on your computer and information sites on what
a virus is and how to prevent infection. Please make sure you protect YOUR system
and prevent further spread through computer systems worldwide!

Antivirus Software

Nowadays more and more people are using a computer. A lot of them use it at their work place, but an increasing number of computer users have also discovered the need to have a computer at home. At the same time the number of Internet surfers increased.

This is a good thing because people are realizing the advantages offered by the world of technology. As soon as they discover this, they start using computers and the Internet more and more, but at the same time not considering the threats that are coming in from all sides. They should know that if you don’t protect yourself, nobody will. These threats are now coming from everywhere and they are growing in number and complexity. First threats of this kind were the viruses. At first, viruses were not that harmful. They were designed to perform a simple task, like flashing a single message onto the user's computer screen. Also the spread rate was slow, because not many people were connected to the Internet. But now the majority of viruses are programs intentionally written to obstruct with, or harm other programs or computer systems. And they are spreading very fast.

Many companies and people have had a lot of troubles because of these viruses. And so the need for antivirus software was born. At first one very simple antivirus appeared and this was enough. Now, as the threat is growing antivirus software are becoming a lot more complex. Some of them have also included a firewall so to better protect the users. In order to increase the competition, other antivirus software producers have also come up with a wonderful idea: to offer free scan online. This was a big help for people that are frequently using a computer mostly for their personal use, meaning it is not attached to a network and uses the Internet only from time to time. Now, they don’t have to spend a lot of money to buy antivirus software that will be used very rarely.

Most of these antivirus programs have to be bought in order for you to use them at their full capacity. Also you have the option to test a so called “free trial version”. These trial versions include all or most of the software’s features, and are available to be checked out by the user for a short period of time, usually 30 days. After these 30 days, the program can no longer be used. Other antivirus software producers use another method; they offer a free trial version that you can keep forever. But it is not fully operational, meaning some of the options of the program cannot be used as they are not activated. After you have tried a program and you consider it is fit for your need, then you’ll have to buy it to protect your computer at its full capacity.

Lately, viruses are mostly spread through e-mails because this is the most common use of the Internet. Also, e-mail viruses are easier to develop. E-mail viruses make use of the ability of having macros or scripts implanted in word documents, spreadsheets, HTML pages, and are programmed to run when the document is opened. But how does an e-mail virus works? When an e-mail with an infected document or program is received, the user unknowingly opens a document/program, which in turn executes a code to open the e-mail directory and to send a copy of itself as an e-mail attachment to a certain number of addresses. Some of the recipients of the e-mail open its attachment and the process repeats itself.

This is where the antivirus program comes in. This program is set to check all incoming and outgoing messages and their attachments. If an e-mail is detected to have a document or program infected with a virus the program offers several possibilities to deal with the threat: delete the e-mail, put it in quarantine or try to disinfect it. Most of the -
times, these choices are left to the user’s decision. It is up to the user to set the program in such manner to best fit his needs. But not all viruses are coming by e-mail. A few of them use security errors in the operating system or your Internet browser to be launched automatically. But if you keep your antivirus and all the other programs updated, there will be a small chance of being infected via this route.

Nowadays, most viruses are spread in the form of e-mail attachments. This is because some of the worst recent viruses relay on recipients that throw away common sense and launch a deadly e-mail attachment. Commonly the attachments are with extensions that include .bat, .com, .exe, .pif, .scr, and .vbs. Sometimes to avoid the filters of antivirus software, virus creators enclose their malicious code in a .zip or .rar archive file. The file might even have a password to full antivirus programs that scan inside archives. And obviously, the password is included in the message as an image for the convenience of the naive user. As a simple but reliable rule, you should never open an attachment that you didn’t expect to receive, even if it came from someone you know. Also, make sure your e-mail software is configured so it will not automatically open attachments.

Another common way of spreading viruses is file sharing. Many viruses spread themselves throughout open network shares. You can protect your computer not sharing files or directories over the network. But if you don’t have a choice and you have to share your files, you are still able to reduce the risk of being infected by installing antivirus software and keeping it updated. Other ways to become infected with viruses are downloading files or software from the Internet, instant messaging or even web pages.

If the file you are downloading or the computer you are downloading it from is infected with a virus, there is a big chance that your computer will also become infected with the virus. As for the instant messaging, the major risk comes from accepting files from other users on the network. This risk can be minimized by configuring your antivirus software to scan all incoming files and also configure your other programs not to automatically accept files, and not to automatically execute the files you accept. Certain viruses are known to infect web servers. If you visit a website from an infected server, your computer could be infected with the same virus, but this is a very rare method of infection.

There are many different threats that are targeting the computers. Although they are very different, all of them are popularly called viruses. A virus by definition is a self-replicating file, not considering whether it is malicious or not. Another type of the so called viruses are worms; they circulate mainly through e-mail but also spread through a network. A worm is aware he is located in a network and uses it for replicating itself. Trojan horses (or trojans) are mostly used to insert some remote tools into a system in order to give the attacker free access to that system, without the user’s knowledge. Most Trojan horses cannot replicate automatically.

With the increased number of Internet users, the existing threats are also raising as now there are many more computers to attack and more people that don’t know to stay away from these threats. But the antivirus software producers are making it easier for us. There is a lot of antivirus software which cover a lot of threats. All we have to do is install one.

Antivirus Software – Get The Bugs Before They Get You!

You turn on your computer, and it doesn’t look quite right. Maybe your icons have changed, or the background picture is wrong. Some options are disabled. Even worse, you may not be able to boot your computer up at all. Guess what – it’s probably got a virus.


In today’s online world, protecting your computer from all the nasty things online is vital. Viruses can cause obvious issues, as described above, but they can also run silently in the background, propagating themselves across your computer and transferring on to the computers of people you know. Mostly, you only know you have a virus when substantial damage has already been done.

Some common signs of a virus include:

-Programs working erratically
-Computer locks up
-Greyed out options
-The browser home page has changed
-Icons have changed
-Difficulties starting up the computer

There is a solution! Antivirus software is readily available, and the good ones are very efficient at dealing with viruses in all their many and varied mutations. Basically, if you’re online, you need this type of software.

So which one do you choose? For starters, be careful of using something free off the internet, particularly if it’s one you’ve never heard of. Sometimes these programs are a way of implanting more viruses on your computer. Some of the better known brands give you the option of doing a free scan online, which is useful, but not a long term solution.

It’s really important to choose well-known antivirus software. Ask friends, or someone computer savvy, for their recommendations. It may be worth visiting a
computer store and buying it there, rather than online – after all, if they’ve gone to the trouble of stocking it, it’s most likely an established and trusted product.

There are plenty of good brands available, far too numerous to list here, but some of the best known are from McAfee, Norton and Trend. Check out the support available to you – can you contact someone if you have trouble installing the software?

Most importantly, make sure there’s an easy way to update the software on a regular basis (preferably as part of the purchase cost!). For example, my antivirus software pops up a little box every time an upgrade is available. I click okay, and it’s automatically downloaded to my computer. Viruses change and develop at an alarming rate, so it’s vital to keep your antivirus software up to date.

Finally, the all-important backup! The word “backup” tends to produce the same glassy eyed response as the word “budget”, but it really is an essential part of being online. Regularly backup your important files to CD or DVD. If you’re a business user, an automated and frequent backup process is vital. Once a virus has destroyed your computer, it’s too late.

Being online is wonderful, but don’t let it become a nightmare. Antivirus software will play a vital role in keeping your online experience a positive one.

All About Computer Viruses

Your computer is as slow as molasses. Your mouse freezes every 15 minutes, and that Microsoft Word program just won’t seem to open.

You might have a virus.

Just what exactly is a virus? What kind is in your computer? How did it get there? How is it spreading and wreaking such havoc? And why is it bothering with your computer anyway?


Viruses are pieces of programming code that make copies of themselves, or replicate, inside your computer without asking your explicit written permission to do so. Forget getting your permission down on paper. Viruses don’t bother to seek your permission at all! Very invasive.

In comparison, there are pieces of code that might replicate inside your computer, say something your IT guy thinks you need. But the code spreads, perhaps throughout your office network, with your consent (or at least your IT guy’s consent). These types of replicating code are called agents, said Jimmy Kuo, a research fellow with McAfee AVERT, a research arm of anti-virus software-maker McAfee Inc.

In this article, though, we’re not talking about the good guys, or the agents. We’ll be talking about the bad guys, the viruses.

A long, long time ago in computer years, like five, most viruses were comprised of a similar breed. They entered your computer perhaps through an email attachment or a floppy disk (remember those?). Then they attached themselves to one of your files, say your Microsoft Word program.

When you opened your Microsoft Word program, the virus replicated and attached itself to other files. These could be other random files on your hard drive, the files furthest away from your Microsoft Word program, or other files, depending on how the virus writer wanted the virus to behave.

This virus code could contain hundreds or thousands of instructions. When it replicates it inserts those instructions, into the files it infects, said Carey Nachenberg, Chief Architect at Symantec Research Labs, an arm of anti-virus software-maker Symantec. Corp.

Because so many other types of viruses exist now, the kind just described is called a classic virus. Classic viruses still exist but they’re not quite as prevalent as they used to be. (Perhaps we could put classic viruses on the shelf with Hemingway and Dickens.)

These days, in the modern era, viruses are known to spread through vulnerabilities in web browsers, files shared over the internet, emails themselves, and computer networks.

As far as web browsers are concerned, Microsoft’s Internet Explorer takes most of the heat for spreading viruses because it’s used by more people for web surfing than any other browser.

Nevertheless, “Any web browser potentially has vulnerabilities,” Nachenberg said.

For instance, let’s say you go to a website in IE you have every reason to think is safe, Nachenberg said.

But unfortunately it isn’t. It has virus code hidden in its background that IE isn’t protecting you from. While you’re looking at the site, the virus is downloaded onto your computer, he said. That’s one way of catching a nasty virus.

During the past two years, another prevalent way to catch a virus has been through downloads computer users share with one another, mostly on music sharing sites, Kuo said. On Limewire or Kazaa, for instance, teenagers or other music enthusiasts might think they’re downloading that latest Justin Timberlake song, when in reality they’re downloading a virus straight into their computer. It’s easy for a virus writer to put a download with a virus on one of these sites because everyone’s sharing with everyone else anyway.

Here’s one you might not have thought of. If you use Outlook or Outlook Express to send and receive email, do you have a preview pane below your list of emails that shows the contents of the email you have highlighted? If so, you may be putting yourself at risk.

Some viruses, though a small percentage according to Nachenberg, are inserted straight into emails themselves.

Forget opening the attachment. All you have to do is view the email to potentially get a virus, Kuo added. For instance, have you ever opened or viewed an email that states it’s “loading”? Well, once everything is “loaded,” a virus in the email might just load onto your computer.

So if I were you, I’d click on View on the toolbar in your Outlook or Outlook Express and close the preview pane. (You have to click on View and then Layout in Outlook Express.)

On a network at work? You could get a virus that way. Worms are viruses that come into your computer via networks, Kuo said. They travel from machine to machine and, unlike, the classic viruses, they attack the machine itself rather than individual files.

Worms sit in your working memory, or RAM,
Nachenberg said.

OK, so we’ve talked about how the viruses get into a computer. How do they cause so much damage once they’re there?

Let’s say you’ve caught a classic virus, one that replicates and attacks various files on your computer. Let’s go back to the example of the virus that initially infects your Microsoft Word program.

Well, it might eventually cause that program to crash, Nachenberg said. It also might cause damage to your computer as it looks for new targets to infect.

This process of infecting targets and looking for new ones could eventually use up your computer’s ability to function, he said.

Often the destruction a virus causes is pegged to a certain event or date and time, called a trigger. For instance, a virus could be programmed to lay dormant until January 28. When that date rolls around, though, it may be programmed to do something as innocuous but annoying as splash popups on your screen, or something as severe as reformat your computer’s hard drive, Nachenberg said.

There are other potential reasons, though, for a virus to cause your computer to be acting slow or in weird ways. And that leads us to a new segment – the reason virus writers would want to waste their time creating viruses in the first place.

The majority of viruses are still written by teenagers looking for some notoriety, Nachenberg said. But a growing segment of the virus-writing population has other intentions in mind.

For these other intentions, we first need to explain the “backdoor” concept.

The sole purpose of some viruses is to create a vulnerability in your computer. Once it creates this hole of sorts, or backdoor, it signals home to mama or dada virus writer (kind of like in E.T.). Once the virus writer receives the signal, they can use and abuse your computer to their own likings.

Trojans are sometimes used to open backdoors. In fact that is usually their sole purpose, Kuo said.

Trojans are pieces of code you might download onto your computer, say, from a newsgroup. As in the Trojan War they are named after, they are usually disguised as innocuous pieces of code. But Trojans aren’t considered viruses because they don’t replicate.

Now back to the real viruses. Let’s say we have Joe Shmo virus writer. He sends out a virus that ends up infecting a thousand machines. But he doesn’t want the feds on his case. So he instructs the viruses on the various machines to send their signals, not of course to his computer, but to a place that can’t be traced. Hotmail email happens to be an example of one such place, Kuo said.

OK, so the virus writers now control these computers. What will they use them for?

One use is to send spam. Once that backdoor is open, they bounce spam off of those computers and send it to other machines, Nachenberg said.

That’s right. Some spam you have in your email right now may have been originally sent to other innocent computers before it came to yours so that it could remain in disguise. If the authorities could track down the original senders of spam, they could crack down on spam itself. Spam senders don’t want that.

Ever heard of phishing emails? Those are the ones that purport to be from your internet service provider or bank. They typically request some information from you, like your credit card number. The problem is, they’re NOT from your internet service provider or your bank. They’re from evil people after your credit card number! Well, these emails are often sent the same way spam is sent, by sending them via innocent computers.

Of course makers of anti-virus software use a variety of methods to combat the onslaught of viruses. Norton, for instance, uses signature scanning, Nachenberg said.

Signature scanning is similar to the process of looking for DNA fingerprints, he said. Norton examines programming code to find what viruses are made of. It adds those bad instructions it finds to its large database of other bad code. Then it uses this vast database to seek out and match the code in it with similar code in your computer. When it finds such virus code, it lets you know!

A Beginner's Guide to Avoiding Viruses

“Aaaaaahhhhhh! I’ve been invaded by a virus!” Getting a virus means getting sick and no one in their right mind wants to be ill. Well, now that computers have become our close friends, it’s a shock to learn that foreign bodies too can invade them with malicious intent. No, your computer doesn’t get a runny nose or diarrhea. This is a sickness that stops your friend from functioning properly, sick in bed, incapacitated.

“Aaaaaahhhhhh! I’ve been invaded by a virus!” Getting a virus means getting sick and no one in their right mind wants to be ill. Well, now that computers have become our close friends, it’s a shock to learn that foreign bodies too can invade them with malicious intent. No, your computer doesn’t get a runny nose or diarrhea. This is a sickness that stops your friend from functioning properly, sick in bed, incapacitated.

Well in Nature viruses occur from a power outside of our control. But, with computers it’s different, humans, mean or ignorant humans are creating these viruses. Why? Usually these are disgruntled people who want to wreak some havoc on others or companies that they feel have done wrong to them. In any case we have to be in the know and prepared to deal with these debilitating scourges.

There are many ways to approach the protection of your computer. First of all there’s the step of awareness. Be aware of how viruses are transmitted. You can catch them from a disc but in most cases it is through your email system. Check your email carefully. Be very wary of anything that has an attachment. Check whom it’s from and look at the title of the mail, is it something you were expecting? Even if it’s from someone you know, be careful as their computer could be infected and the virus being transmitted without their knowledge.

Next, read the cover message, you can’t catch the disease without actually opening the message. Look at the name of the attachment; remember viruses are written to entice you. Beware of free offers and generally anything from people you don’t know, as well as messages that sound irrelevant to your
contact’s usual style. Delete them straight away. Delete, delete, delete. This will ensure you of a lower risk of infection. You can even send the message back to the sender without opening it to make sure it is valid.

Now for the heavy protection: Virus scanning and virus protection software, and rescue discs are all readily available and easily utilized. Some are free, and others are obtained for a very small charge. Most software manufacturers offer subscriptions for updating services, which automatically download protection to the latest viruses.

There are two main types of virus scanning software: one searches through your entire computer files looking for recognizable viral signatures, the other scans your incoming and outgoing emails. Alerts will show you when a file needs to be erased or repaired. If you do receive a virus that none of the software can repair you can send a copy of it to a company like Symantec who will be happy to develop a cure for it.

The main message here is not to get too worried about your good friend Mrs. PC getting ill or sick. The humans are on top of the case and they seem much better adapted at fixing their technology than they are at beating the viruses that attack our physical bodies. If only we could cure human virus and illness as easily as we solve the problem of computer sickness.

9 Steps to Protect your MS Windows System from Viruses

Nowadays as the Internet and other networks are greatly developed computer viruses are distributed rapidly and intensively. Everyday several new viruses capable to damage considerably your computer system arise. Anti-virus specialists work hardly to make updates their software against new viruses as soon as possible. The viruses can get inside computer in different ways. That is why there is no simple method to protect system. Only series of measures can give you reliable protection from the infection. Below are 9 steps to protect MS Windows based PC system from viruses.


1. Make regular backups. It should be said that there is no absolutely safe way of protection. Virus creators regularly find holes in new computer products to use them for infection of computer systems. Some dangerous viruses can considerably damage data files or even erase entire file system. Make regular backups of your data files to separate file storage device. It can be separate hard drive, flash card, compact disc or another file storage device which you choose. To ease the procedure you can use some automatic backup software. And be ready if the system will die because of virus infection.

2. Be ready to reinstall your system if it dies because of viruses. Get distributives of your operation system and distributives of software which you use and keep them together, for instance, on a set of CDs not far away from you. In this case if virus infection will cause unrecoverable system failure you can rapidly reinstall your working medium.

3. Protect your network connection with Firewall. Firewall is a software which blocks suspicious potentially dangerous connections to preventing viruses from network to penetrate into your system. Windows XP system has quit simple but reliable built-in firewall. You can enable it as follows. 1) in Control Panel, double-click Networking and Internet Connections, and then click Network Connections. 2) Right-click the connection on which you would like to enable firewall, and then click Properties. 3) On the Advanced tab, check the option to Protect my computer and network.

If you need more flexible control of connections with network you -
can get and install more advanced firewall software like Norton Personal Firewall or Outpost Firewall. If you use this software you have ability to permit or to block particular connections and to monitor network activity.

4. Use antivirus software. Install antivirus software which will scan your system searching and erasing viruses on a regular basis. Leaders in antivirus software products for Windows systems are Norton Antivirus, McAfee, Kaspersky Anti-Virus and PC-cilin.

5. Regularly update operating system. Windows XP has built-in automatic update service. It regularly contacts Microsoft server to find updates and notifies you if updates are ready to be installed. Updates are important because hackers regularly find holes in operating system which are often used by virus creators.

6. Don't install and don't run suspicious software. Check new programs which you are going to install with anti-virus software. Don't download software from suspicious websites. To download software always seek website of software creator or official distributor. Do not open applications received by email from unknown persons.

7. Limit access to your computer. Protect enter to system with password.

8. If you use Internet Explorer, consider moving to another browser. As IE is the most distributed browser today virus creators actively use defects in its security system to infect computers. Infection may arise if you will visit webpage which contains invisible harmful code. You are more safe if you use less known browser only because virus creators do not pay much attention to it. Major IE competitors Firefox and Opera browsers provide now the same comfortable interface and range of services for working on the Web.

9. Use spam protection. Viruses are often distributed via email. Switch on spam filters in your email box to block spam receiving. If you need assistance with using of the filters you can ask your email service provider.
