Computer-Virus Writer's: A Few Bats In The Belfry?

Computer-Virus Writer's: A Few Bats In The Belfry?

by: Dean Phillips

"Male. Obsessed with computers. Lacking a girlfriend. Aged
14 to 34. Capable of creating chaos worldwide."
The above description is the profile of the average computer-virus writer, according to Jan Hruska, the chief executive of British-based Sophos PLC, the world's fourth-largest anti-virus solutions provider.
"They have a chronic lack of girlfriends, are usually
socially inadequate and are drawn compulsively to write self-
replicating codes. It's a form of digital graffiti to them,"
Hruska added.
To create and spread cyber infections, virus writers explore
known bugs in existing software, or look for vulnerabilities
in new versions.
With more and more new OS (operating system) versions, there
will be more new forms of viruses, as every single software
or OS will carry new features, and new executables that can
be carriers of the infection.
Executables are files that launch applications in a
computer's operating system, and feature more prominently in
new platforms like Microsoft's Windows 2000 and Windows XP
than they did in the older DOS or Windows 3.1.
Virus writers also share information to create variants of
the same infection, such as the Klez worm, which has been
among the world's most prolific viruses.
The Klez, a mass-mailing worm that originated in November
2001, propagates via e-mail using a wide variety of messages
and destroys files on local and network drives.
But the news gets worse. Recent events have uncovered what
may be a new trend: spammers paying virus writers to create
worms that plant an open proxy, which the spammer then can
use to forward spam automatically. Many suspect this
occurred with the SoBig virus.
The Sobig worms, began spreading in the early part of
2003. The unusual thing about them was they contained an
expiration date and were given a short life cycle to see how
features worked in the wild.
Having an expiration date also makes the virus more
dangerous, because most people would have been alerted to
the new worm within a few weeks and anti-virus definitions
would have been updated.
A variant of Sobig, Sobig-F was so efficient that just a few
infected machines could send thousands of messages. Sobig-F
created a denial-of-service effect on some networks, as e-
mail servers became clogged with copies of the worm.
According to Mikko Hypponen, manager of anti-virus research
for Finland-based F-Secure Corp, Sobig-F sent an estimated 300 million copies of itself.
Computer Economics, Inc. states, "Nearly 63,000 viruses have
rolled through the Internet, causing an estimated $65
billion in damage." However criminal prosecutions have been
few, penalties light and just a handful of people have gone
to prison for spreading the destructive bugs.
Why is so little being done? Antiquated laws and, for many
years, as crazy as it sounds, a "wink, wink" or even admiring attitude toward virus creators.
One person has been sent to prison in the United States and
just two in Britain, authorities say. But the low numbers
are "not reflective of how seriously we take these cases,
but more reflective of the fact that these are very hard
cases to prosecute," said Chris Painter, the deputy chief of computer crimes at the U.S. Department of Justice.
So what can you do to protect yourself against computer viruses?
Well, first and foremost, make sure you have proven anti-virus protection like like Symantec's Norton Anti-Virus or McAfee's ViruScan.
In addition, If you haven't already done so, I highly recommend installing Microsoft's Service Pack 2. SP2 tightens your PC's security with a new Windows Firewall, an improved Automatic Updates feature, and a pop-up ad blocker for Internet Explorer. Plus, the newly minted Security Center gives you one easy-to-use interface for keeping tabs on your PC's security apps.
"Male. Obsessed with computers. Lacking a girlfriend. Aged
14 to 34. Capable of creating chaos worldwide."
Now, I'm no psychiatrist, but to me, the above description
sounds more like someone with a few "bats in the belfry!"

Help Keep the Computers on Earth Clean and Healthy

Help Keep the Computers on Earth Clean and Healthy

by: Jesse S. Somer

“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.

Keeping it Clean: Virus Removal Basics

by: John Lenaghan

The day you learn your computer is infected with a virus or spyware is a lonely yet aggravating day. You’ll be angry that you fell victim, and may feel helpless because of your lack of knowledge about virus removal or pc repair. But don’t worry - you’re not alone! Unfortunately, you’re actually part of a club of tens of thousands of people who feel the same way every day!
According to AVG, virus protection usually doesn’t detect adware or spyware both of which can wreak havoc on a computer. Thousands of people each day are infected with malicious programs! Worry no longer and stop feeling helpless because this guide is a basic computer virus repair guide that will help you identify and remove viruses and malware.
Are You Running Antivirus Software?
If you already have virus software perform an update for the latest version and then run a system scan. If you do not have such software, download a free copy of AVG virus protection at http://www.grisoft.com/doc/40/lng/us/tpl/tpl01. This will give you free real time virus protection, email scanning and virus removal tools.
Next, download and run Ad-Aware to remove spyware, adware, and other troublesome programs http://www.lavasoftusa.com/software/adaware/. Then download SpyBot Search & Destroy http://www.safer-networking.org/en/download/index.html. By using Ad-Aware and SpyBot you will have excellent protection against files that are often missed by virus protection.
To check for and eliminate browser hijackers, download and run CWShredder at http://www.intermute.com/spysubtract/cwshredder_download.html.
With the above programs simply run a scan and follow the prompts to remove any infected files or unwanted programs. Once that is done, upgrade your operating system, or download any needed patches, then reboot your computer.
These steps won’t solve every problem, but they will fix a large percentage of the things that cause your computer to act up.

Do The Media Spread Computer Viruses?

Do The Media Spread Computer Viruses?

by: Joel Walsh

Summary: Could the mass media hype about computer viruses actually make the problem worse?
If you believe what you hear in the media, there are an awful lot of viruses going around. No, I'm not talking about the make-you-sick kind of virus, though they get plenty of airtime, too. I'm talking about the kind of virus that enters via your internet connection rather than your nasal passages.
What the mainstream media often don't tell you--at least, in most radio and television newscasts and in the crucial headlines and opening paragraphs of newspaper articles-- is that many of these "viruses" are not viruses at all.
What Computer Viruses Really Are
The main reason the mainstream media always are in alarm over viruses is that they tend to call any malicious computer program a virus. In reality, there are at least eleven distinct types of malicious software, or malware, commonly affecting computers today. The most common of these are worms, Trojans, and spyware.
So, what's the difference between computer viruses and the other types of malware? The difference is that computer viruses are just about the only ones that regularly shut down computers and cause other obvious damage. The most common of the other kinds of malware--worms, Trojans, and spyware--are usually only detectable with a special scan.
The Real Danger of Computer Viruses
If the other types of malware are so unobtrusive that they can only be detected with a special scan, then what's to worry about? For starters, these programs are called malicious for a reason: they are designed to cause some kind of damage, if not to your computer, then to someone else's.
Worms are most famously used to damage, destroy, or disrupt other computer networks than the one on which the host computer is located. For instance, worms have been used by website owners to shut down rival websites by sending overwhelming numbers of requests to the computer that hosts that website. Worms have also been used to send out viruses to other computers, often without infecting the host machine--after all, what would it benefit the worm to shut down its host computer?
Trojans, in turn, are often used to insert worms and other malware on your computer, even if the Trojan itself does no damage.
But even if you don't care what happens to anyone else, you should still be concerned about one kind of malware: spyware, a kind of malware that, true to its name, collects data from your computer and sends it back to a remote host.
Most spyware is only interested in monitoring your internet usage so it can tell other programs, called adware, what advertising to popup on your computer. However, there are criminal spyware programs that steal financial data, or perform a thorough identity theft. Don't think you have personal or financial data on your computer? Some spyware programs contain a keylogger, which is a program that copies whatever you type, usually in order to snatch passwords. Even if you keep no financial information on your computer, if you ever buy anything over the web, the keylogger would allow its owner to buy stuff using the same information you typed in to buy stuff yourself.
Why Blame the Media?
Given the danger of all these different types of malware, isn't it a good thing that the mass media are becoming hysterical about it? And can't they be forgiven the sloppy reporting of calling Trojans, worms, spyware, and other malware "viruses"?
No, no, no.
This is a classic case of bad reporting doing more damage than no reporting at all. In this case, the damage bad reporting has done is to promote a common myth that goes something like this: "The only malicious software is a virus. Viruses damage your computer. Therefore, if my computer is working OK, my computer has no malicious software. I only need to scan my computer for problems when there is a sign of problems."
Thanks to this myth, many people complacently let their antivirus software go months out of date, not wanting to be bothered with scheduling an automatic update. Just as bad, many people don't have any extra software to combat the other types of malware that may not be covered by antivirus software.
In fact, it's not uncommon for people who have found malware on their computers after a scan to say, "but I never had malware on my computer before!" But how would they have known if they had never scanned!
Until the biggest mainstream media--and especially television--start educating the public about the need to have their computers automatically scanned at least daily, the world will continue to have major, drawn-out problems with malware that could have been wiped out as soon as soon as the anti-malware software makers discovered it.
And until that day, the mainstream media will have many more opportunities to run hysterical stories about "viruses," thereby forcing them to sell more newspapers and broadcast to even larger audiences of people who suck at the information trough yet somehow never become full.

Internet Security Basics 101

Internet Security Basics 101

by: Niall Roche

The explosive growth of the Internet has meant that thousands of people are today experiencing the joys of being online for the first time. With growth there always comes pain. Be it your growing pains as a child or the growth and development of this part of our culture called the Internet.
Firstly we need to quickly explain what the Internet is and where it came from. The Internet is the offspring of a military project called Arpanet. Arpanet was designed to provide reliable communication during global nuclear war. A vast network of interconnected computers was set up all over the world to allow the various branches of US and NATO forces to communicate with each other.
Nuclear war never came (thankfully) and the world was left with a massive network of computers all connected together with nothing to do. Colleges and universities started to use these computers for sharing research internationally. From there it grew and spread outside colleges to local homes and businesses. The World Wide Web was born and its father was a guy called Tim Berners Lee.
When you're connected to the Internet you're sharing a vast network with hundreds of millions of other users. This shared network provides resources that 15 years ago were never thought possible. Unfortunately when something is shared its open to abuse. On the Internet this abuse comes from hackers and virus creators. Their sole intent is to cause chaos and/or harm to your computer system and millions of other computer systems all over the world.
How do you combat this? You need an Internet security system. This might sound complicated but your Internet security system will be quite straigtforward being comprised of just 2 - 3 Internet security products. We'll look at each of these products in more detail now:
AntiVirus Software
The first and most critical element of your Internet security system is antivirus software. If you don't have up-to-date antivirus software on your PC you're asking for trouble. 300 new viruses appear each month and if you're not constantly protecting your system against this threat your computer will become infected with at least one virus - it's only a matter of time.
Antivirus software scans your PC for signatures of a virus. A virus signature is the unique part of that virus. It can be a a file name, how the virus behaves or the size of the virus file itself. Good antivirus software will find viruses that haven't yet infected your PC and eliminate the ones that have.
Antivirus software can only protect your computer from viruses trying to infect it via email, CD-Rom, floppy disk, Word documents or other types of computer files. Antivirus software alone will not keep your computer 100% safe. You also need to use firewall software.
Firewall Software
The use of firewall software by home computer users is a relatively new occurence. All Internet connections are a two way process. Data must be sent and received by your computer. This data is sent through something called ports. These are not physical things rather aspects of the way your computer communicates online.
Firewall software watches these ports to make sure that only safe communication is happening between your computer and other computers online. If it sees something dangerous happening it blocks that port on your computer to make sure your computer stays safe from the person who is trying to hack into your system.
An easier way to understand a firewall would be to picture your computer as an apartment complex. At the front door of this complex there is a security guard. Every person who enters the complex must pass this security guard. If the security guard recognizes the person entering as a resident he allows them to pass without saying anything. If, however, the person entering the complex is unknown to him then he will stop that person and ask for identification. If they have no business being at the apartment complex he escorts them from the building.
If you are not currently using firewall software your computer will get hacked into - that's a guarantee.
PopUP Blocker
You can get a good popup blocker at no cost. An easy way to do this is to install either the Google or Yahoo toolbar. Both of these come with popup blockers built in. Popups are not necessarily dangerous but are a nuisance and using either of these toolbars will make your life that bit easier.
A simple rule for practicing online security is: "If in doubt then don't". If you don't recognize the file, the email address, the website or if your gut feeling says "no" then don't click that button.

Does Your PC Have Worms?

Does Your PC Have Worms?

by: Joel Walsh

Worms aren't just for dogs anymore. Find out how to inoculate your computer against these nasty parasites.
What Are Worms?
Worms are descended from viruses and are even nastier. Just as ever stronger doses of pesticide breed ever more resilient locusts, better and better anti-spyware software bred ever more devious viruses.
Finally, some virus designers stopped having their creations infect and take over files the way real viruses infect and take over cells. Instead, they created programs that could stand on their own and cause plenty of trouble without the help of any other software applications. Just worms are independent organisms that can infect a host directly, so do computer worms infect computers directly.
What Do Worms Do?
Worm designers are often even more sinister than virus designers, since worm designers are not just vandals. Worm designers often use their creations to achieve specific goals:
• Backdoor creation. Worms often try to set up another kind of malware, a backdoor. A backdoor is a hidden opening in your network connection that lets the worm send data out and take data in. Practically speaking, the data it's sending out are often spam emails, and the data it takes in are instructions on spam emails to send.
• Denial of service attack. Some worm designers really are vandals rather than profit-hungry con artists sending spam. But their vandalism can be more targeted. They use worms to send out numerous requests to remote computers, such as web servers, in order to overwhelm them and therefore shut them down. This is called a denial of service attack.
• Spyware, Trojan, adware, and virus installation. Worms are often used simply to unleash other forms of malware on a computer that might otherwise block them.
• Information theft and fraud.Worms can multitask in order to set up spyware that gathers sensitive information--often financial information--and then set up backdoors, Trojans, viruses, or dialers to disseminate the stolen data.
How Do Worms End Up on a PC?
Worms enter PCs just as viruses, spyware and other malware do: any way they can! Some favorite points of entry for worms:
• Websites can actually download software to your computer without you realizing it. This software includes not only worms, but also spyware, adware, viruses, and other malware. These malware programs find their way into websites either by the deliberate design of the site owner or because hackers have installed the software on the website's server.
• Peer-to-peer file-sharing networkscontain many nice-enough-looking files that are really worms. One of the sneakiest disguises is a filename that indicates the spyware is really a video of a beautiful actress.
• Email, the favored route of viruses, can still be exploited by Spyware. But since new email programs usually block the automatic opening of file attachments, this is less of a problem than it used to be.
• Any internet connection inevitably lets data flow both in and out, and so is vulnerable to attacks by worms.
How Do You Get Rid of Worms?
There's really only one good way to make sure your computer is rid of worms: scan it with multiple antivirus and anti-spyware programs using a full-system scan. Worms are tricky, so anything less than a full-system scan might let them escape. Worse, with new worms coming out all the time, some antivirus and anti-spyware packages may not even know about a new worm until after its wreaking havoc on your machine. That's why you should try using more than one antivirus program and more than one anti-spyware program to increase your odds of successfully detecting the malware.
Don't have more than one anti-spyware and antivirus software? You'd better start downloading. After all, worms won't take excuses.

Is Your Computer Sick?

Is Your Computer Sick?

Viruses and spyware usually show up on your computer one of
two ways.
Either they invade your system with a frontal assault like
the Huns attacking the Romans, or they sneak in a back door
like a cat burglar.
Either way, once a virus or piece of spyware gets on your
system, getting it off can rate harder than curing a severe
case of trench foot!
Viruses, malicious programs designed to disrupt normal
computing, and spyware, programs intended to literally "spy"
on your activities, can enter your computer a number of
ways.
Most commonly they enter your system through an email
attachment, by sharing files with an infected computer by
disk, as a "ride along" with a 3rd party program you
install, or through a "back door" port in your computer.
Regardless of how they get on your system, once in place,
they cause no end of headaches and frustration.
The following represent typical signs you may suffer from
infection by a virus or piece of spyware.
Your computer starts acting oddly by doing things it never
did previously.
Your modem starts trying to dial out to the Internet without
you initiating a surfing session.
You notice that files start disappearing, the system stalls,
runs slowly, or even crashes frequently.
Your computer takes progressively longer to boot up every
time you start it or you notice that your available hard
drive space has disappeared. Strange popup windows appear,
even when you're not surfing the web, or you delete a
program and it "magically" reappears next time you boot the
system.
If you suspect you a virus or a piece of spyware has invaded
your computer, follow these steps to first identify and then
delete the offending code:
Step 1 - Back up your important files, but remember to scan
these files for viruses before reinstalling to avoid
accidentally re-infecting your system.
Step 2 - Update your anti-virus definitions and perform a
scan of your hard drive.
If you don't carry virus protection, or you suspect your
anti-virus software got corrupted somehow, then log on to
www.pandasoftware.com and use the free Panda Active Scan
service to check your hard drive for viruses.
Follow the instructions for quarantining and removing the
offending files.
Step 3 - Scan your hard drive with an adware, scumware, or
spyware detection and removal tool like Adaware
www.lavasoft.de/support/download/ or Spybot
http://spybot.safer-networking.de/.
Step 4 - In many cases, when the virus or spyware program
gets installed with a free utility or game you download from
the Web, you must usually uninstall the utility or game to
finally get rid of the problem once and for all.
Step 5 - Avoid re-infection by keeping your anti-virus and
firewall up-to-date at all times.
As a last resort, if you run into a program you simply can't
get rid of, but can figure out the offending file's name, do
a search for the file name on Google.com. Often you will
find you're not the first victim and may get valuable advice
for cleaning up your system.
However, be very careful of the information you find and
think twice before modifying any system files.
