<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Arial">McAfee has released a hotfix for its Security Suite 1.1 for Mac product to address a potential conflict with Apple's FileVault encryption system. The conflict, which affects machines running Mac OS X 10.5 (Leopard) and 10.6 (Snow Leopard), can cause systems to become unresponsive after a user logs in.</p>

There are more than 600 authorities, and the breadth of the situation raises questions about the long term security of the technology. </p>

<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Arial">WordPress, Joomla!, ExpressionEngine and Drupal are examples of applications that enable website owners to build websites using templates and other handy features. These sites can often require little to no coding by a developer. They are managed by the web master or the content authors through a portal requiring a username and password. Once logged in, they can add or edit content, pages and images, as well as change some of the design elements of the site.</p>

If these sites were visited when running Internet Explorer, the visitor could be exposing him or herself to a malware attack. Other such hacks, that take advantage of vulnerabilities in browsers or the site software, are not uncommon.</p>

<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Arial; min-height: 16.0px"><br></p>
<ul style="list-style-type: disc">
<li style="margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Arial">Choose <a href="http://kb.mit.edu/confluence/x/3wNt">strong passwords</a> and do not use the password on any other sites. </li>
<li style="margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Arial">Do a regular auditing of the site, to ensure there have not been any unauthorized changes to the code. </li>
<li style="margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Arial">Be sure to take the website software's latest updates when they become available.</li>
