<b>The most common blunder when the topic of a computer virus arises is that people will often refer to a <strong>Worm or Trojan Horse as a Virus.</strong> While the words Trojan, worm, and virus are used interchangeably, they are<strong> not the same. </strong> </b><br />
<a href="http://suvarnaa.blogspot.com/2011/11/what-is-difference-between-virus-trojan.html" name="more" style="color: #3366cc; text-decoration: none;"></a><br />
<b>Viruses, worms, and Trojan Horses are all<strong> malicious programs</strong> that can cause damage to your computer, but there are <strong>differences between</strong> the three, and knowing those differences can help you to better <strong>protect your computer</strong> from their often<strong> damaging effects.</strong></b><br />
<b></b><div class="note"><b><strong><span style="font-size: small;">What is a Computer Virus ?</span></strong></b></div><b>A <strong>computer Virus</strong> <strong>attaches</strong> itself to a <strong>program</strong> or<strong> file</strong> so it can <strong>spread</strong> from one computer to another, <strong>leaving infections as it travels.</strong> Some viruses cause only mildly annoying effects while others can damage your<strong> hardware, software,</strong> or<strong> files.</strong> Almost all viruses are attached to an <strong>executable file(.exe)</strong>, which means the virus may exist on your computer but it cannot infect your computer unless you <strong>run</strong> or<strong> open</strong> the <strong>malicious program.</strong> It is important to note that a <strong>virus cannot be spread without a human action</strong>, (such as running an infected program) to keep it going. People continue the spread of a computer virus, mostly unknowingly, by<strong> sharing</strong> <strong>infecting files </strong>or <strong>sending e-mails</strong> with viruses as attachments in the e-mail.</b><br />
<br />
<div class="note"><b><span style="font-size: small;"><strong>What is a worm?</strong></span></b></div><b><strong>A Worm</strong> is<strong> similar</strong> to a<strong> virus by its design</strong>, and is considered to be a <strong>sub-class of a virus.</strong> Worms spread from<strong> computer to computer</strong>, but unlike a virus, it has the ability to <strong>travel without any help from a person</strong>. A worm takes advantage of<strong> file</strong> or information transport features on your system, which allows it to travel unaided. <strong>The biggest danger with a worm is its ability to replicate itself on your system,</strong> so rather than your computer sending out a single worm, it could send out<strong> hundreds or thousands of copies</strong> of itself, creating a <strong>huge devastating effect</strong>. One example would be for a worm to send a copy of itself to everyone listed in your<strong> e-mail address book.</strong> Then, the <strong>worm replicates</strong> and sends itself out to everyone listed in each of the<strong> receiver’s address book,</strong> and the manifest continues on down the line. Due to the copying nature of a worm and its ability to travel across networks the end result in most cases is that the <strong>worm consumes too much system memory</strong> (or network bandwidth), causing <strong>Web servers, network servers,</strong> and individual computers to stop responding. In more recent worm attacks such as the much talked about<strong> Blaster Worm</strong>, the worm has been designed to <strong>tunnel into your system</strong> and allow<strong> malicious users</strong> to control your <strong>computer remotely</strong>.</b><br />
<br />
<div class="note"><b><strong><span style="font-size: small;">What is a Trojan?</span></strong></b></div><b><strong>A </strong><strong>Trojan Horse</strong> is full of as much<strong> trickery</strong> as the<strong> mythological Trojan Horse</strong> it was named after. The Trojan Horse, at first glance will appear to be<strong> useful software</strong> but will actually do <strong>damage</strong><strong> once installed</strong> or<strong> run</strong> on your computer. Those on the receiving end of a Trojan Horse are usually <strong>tricked into opening</strong> them because they appear to be receiving legitimate software or files from a legitimate source. The Trojan horse itself would typically be a Windows executable program file, and thus must have an executable filename extension such as<strong> .exe, .com, .scr, .bat,</strong> or <strong>.pif.</strong> Since Windows is sometimes configured by default to hide filename extensions from a user, the Trojan horse is an extension that might be <strong>“masked”</strong> by giving it a name such as<strong> ‘Readme.txt.</strong> <strong>exe’.</strong> With file <strong>extensions hidden</strong>, the user would only see <strong>‘Readme.txt’</strong> and could mistake it for a harmless text file. When the recipient double-clicks on the attachment, the Trojan horse might superficially do what the user expects it to do (open a text file, for example), so as to keep the <strong>victim unaware</strong> of its<strong> real, concealed, objectives. </strong>Meanwhile, it might discreetly <strong>modify</strong> or<strong> delete files, </strong>change the configuration of the computer, or even use the computer as a base from which to <strong>attack local</strong> or <strong>other networks</strong> – possibly joining many other similarly infected computers as part of a distributed<strong> denial-of-service attack</strong>. When a Trojan is activated on your computer, the results can vary. Some Trojans are designed to be more annoying than malicious<strong> (</strong><strong>like changing your desktop, adding silly active desktop icons</strong><strong>)</strong> or they can cause<strong>serious damage by deleting files</strong> and <strong>destroying information</strong> on your system. Trojans are also known to create a<strong> backdoor on your computer</strong> that gives<strong> malicious users access to your system,</strong> possibly <strong>allowing confidential</strong>or<strong> personal information</strong> to be compromised. Unlike viruses and worms,<strong>Trojans do not reproduce by infecting other files nor do they self-replicate.</strong></b><br />
<br />
<b><span style="font-size: small;"></span></b><div class="note"><b><span style="font-size: small;"><strong>Added into the mix, what is called a blended threat?</strong></span></b></div><b>A <strong>blended threat</strong> is a <strong>sophisticated attack</strong> that bundles some of the<strong> worst aspects of viruses,</strong> <strong>worms, Trojan horses</strong> and<strong> malicious code</strong> into <strong>one threat</strong>. Blended threats use server and Internet vulnerabilities to initiate, transmit and spread an attack. This combination of method and techniques means blended threats can <strong>spread quickly </strong>and cause widespread damage.<strong>Characteristics of blended threats include:</strong> causes <strong>harm,</strong> propagates by multiple methods, attacks from <strong>multiple points</strong> and<strong> exploits vulnerabilities.</strong></b><br />
<b>To be considered a blended thread, the attack would normally serve to transport multiple attacks in one payload. For example it wouldn’t just launch a<strong> DoS attack</strong> ” it would also<strong> install a backdoor</strong> and <strong>damage a local system in one shot.</strong> Additionally, blended threats are designed to use multiple modes of transport. For example, a<strong> worm</strong> may travel through e-mail, but a single blended threat could use<strong> multiple routes</strong> such as <strong>e-mail, IRC</strong> and<strong> file-sharing sharing networks.</strong> The actual attack itself is also not limited to a specific act. For example, rather than a specific attack on predetermined <strong>.exe files,</strong> a blended thread could <strong>modify</strong> <strong>exe files, HTML files</strong> and <strong>registry keys </strong>at the same time ” basically it can cause damage within several areas of your network at one time.</b><br />
<b><strong>Blended threats</strong> are considered to be the<strong> worst risk to security</strong> since the<strong>inception of viruses</strong>, as most blended threats<strong> require no human intervention to propagate.</strong></b><br />
<br />
<div class="note"><b><span style="font-size: small;"><strong>Combating Viruses, Worms and Trojan Horses :</strong></span></b></div><b>The first steps to protect your computer are to ensure your <strong>operating system (OS) is up-to-date.</strong> This is essential if you are running a <strong>Microsoft Windows OS</strong>. Secondly, you should have <strong>anti-virus software</strong> installed on your system and <strong>download updates frequently</strong> to ensure your software has the latest fixes for <strong>new viruses, worms,</strong> and<strong> Trojan Horses.</strong> Additionally you want to make sure your<strong> anti-virus program</strong> has the ability to <strong>scan e-mail</strong> and files as they are downloaded from the Internet. This will help prevent malicious programs from even reaching your computer. If this isn’t enough protection, then you may want to consider<strong> installing a firewall </strong>as well.</b><br />
<b>A <strong>firewall</strong> is a system which <strong>prevents unauthorized use</strong> and<strong> access to your computer.</strong> A firewall can be either<strong> hardware</strong> or <strong>softwar</strong><strong>e</strong>.<strong> Hardware firewalls</strong>provide a<strong> strong degree of protection</strong> from most forms of attack coming from the outside world and can be purchased as a <strong>stand-alone product</strong> or in<strong> broadband routers.</strong> Unfortunately, when battling<strong> viruses, worms</strong> and<strong>Trojans,</strong> a<strong> hardware firewall</strong> may be<strong> less effective</strong> than a<strong> software firewall</strong>, as it could possibly ignore embedded worms in<strong> out going e-mails </strong>and see this as regular network traffic. For individual home users, the most <strong>popular firewall</strong> choice is a <strong>software firewall.</strong> A good software firewall will protect your computer from outside attempts to control or gain access your computer, and usually provides additional protection against the most common<strong> Trojan programs</strong> or <strong>e-mail worms. </strong>The downside to software firewalls is that they will only protect the computer they are installed on, not a network.</b><br />
<b>It is important to remember that on its<strong> own a firewall</strong> is unable to get rid of your computer virus problems, but when used in conjunction with<strong> regular operating system updates</strong> and a <strong>good anti-</strong><strong>virus scanning software,</strong> it will<strong>add some extra security</strong> and protection for your computer or network.</b></div></div></div>
