As a web surfer, you're going to have to access a PDF file on the web sooner or later. And to do that, you'll most likely use the free Adobe Acrobat Reader already installed on your computer.
But hackers have started exploiting this software by inserting malicious code into PDFs, which - once they are downloaded - allow the hacker to take control of your computer.
You can read more about this security issue on the web:
While Adobe continually scrabbles to release security patches for the Reader, in the meanwhile you can use the more-secure free version of the Foxit Reader for Windows operating systems. (Warning: when loading the Foxit program, you'll probably want to uncheck the box where it says to "Make Ask my browser default search provider," and also uncheck the option directly below that which says, "Set Ask.com as my home page." These options - already conveniently checked! - are hidden within a block of small text and are difficult to spot.)

Mac owners need not worry about downloading alternative software, since they already have their own built-in PDF software for viewing or printing. However, make sure you have downloaded the latest Mac OS X updates to shore up security holes in its operating system, which include PDF vulnerabilities.
