			<content:encoded><![CDATA[<p class="blogtext">Nobody would even think that the web developers would be worried about the viruses in particular. But the fact is that it is getting harder to hide from the smart virus writers. The most common SirCam virus is so dangerous that it is capable of searching the cached web pages or the email addresses. As this virus has an inbuilt mail server, it makes use of those email addresses for sending out the annoying spam email messages. The worst part is that this spammer is not used for sending any mail, but instead sends a virus to all the recipients.   <span id="more-127"></span></p>
<p class="blogtext">How to protect yourself?</p>
<p class="blogtext">•	Add anti-spam messages to your email addresses:  These are special messages that cannot be recognised by a virus or a spambot but a person would easily be able to strip out.<br />
•	Take off your email address from your web pages:  Make use of feedback forms where your email address was embedded in the CGI and not the HTML. The main reason of using the CGI here is that CGI cannot be cached and at the same time, you can still get your comments.<br />
•	Convert your email address to an image:  Viruses and spammer programs cannot cache the images in the same way as they would be grabbing the email addresses. Always ensure that your email address is not included in your alt text.<br />
•	Make use of the JavaScript for building your mailto field:  Try to use the JavaScript with variables which has been used for splitting up your email address, for building up mailto link, which cannot be read by the spambots.</p>
<p class="blogtext">Anti-Spam Messages in the Email Address<br />
The easiest method of preventing the viruses and spam from spreading is by making use of the Anti Spam messages. Just add the words that would be recognised and should be removed from your email address in the mailto field.</p>
<p>The biggest drawback o using this method is that people easily skip out on the email addresses while clicking on the mailto link. And there is every possibility that if a bounce back message is received by them, it will be simply deleted.</p>
<p class="blogtext">Removing the email addresses<br />
The most effective method of avoiding span or viruses would be to remove completely your email addresses. You just need to create a web form and send the mail using the CGI. Although there are variety of forms to email CGI is available but it is quite imperative to concentrate on the one which has the ability to store the email addresses in the CGI itself. Virus or a spambot can easily get the email address it is in the HTML.<br />
The biggest drawback of this that people avoid using them as they feel more impersonal. Many of the customers who would have otherwise intimated you about the broken link will think twice before intimating you.</p>
<p class="blogtext">Convert Email Addresses to Images<br />
If you have the comfort with the graphics, you can easily convert your email addresses to the images. There is a free Windows tool available for converting the email addresses to the image format for hiding from the spammers.</p>
<p>The biggest drawback o this is that once your email address is converted to an image, it cannot be used in the mailto tag. Also, your email address will have to be written by the customers themselves which can also cause typographical errors.</p>
<p class="blogtext">JavaScript to hide the email addresses<br />
It is considered to be the most effective ways of hiding your email addresses from the viruses and the spambots, but always ensure that your customers have the convenience o using the mailto link.</p>
<p>The biggest drawback of this is that certain people work with the JavaScript turned off due to security reasons. The mailto link for these people will not be effective at all.</p>
