Don't open any PDF files until you read this!

It seems like forever since we've heard about a serious problem with Adobe Reader. Last year, there was a new security flaw every few weeks.

One reason for the lack of security problems lately is that Adobe introduced sandboxing when it released Adobe Reader X. Sandboxing means that any malicious PDF files stay trapped in Reader; they can't get out and affect your operating system.

The latest popular browsers use similar sandboxing for security. Click here to learn how to update your browser to make it more secure and faster.

Unfortunately for Adobe and you, hackers just found a way around Reader's sandbox. Even worse, they've added the information to the most popular hacker toolkit, so every hacker can use it.

If that wasn't enough, Adobe doesn't know what the problem is yet, so it can't release a fix. Yikes! This is why I issued this really important security alert.

What that means for you is that opening PDF files is about to become very risky. You'll want to follow these rules to stay safe.

1. I know you know this, but just in case you might need a reminder. Don't open unsolicited email attachments from unknown senders. If you do know the sender, check with them first to make sure they meant to send you the file.

Remember that major companies won't send you file attachments. They'll offer files for download on their site.

2. Watch whatever you download. Browsers use your default PDF reader, usually Adobe Reader, to display PDF files. A malicious PDF can still escape from the in-browser reader and attack your browser and operating system.

PDF files from secure and trusted sites, such as your monthly statement from a financial institution, are OK. Just verify that you're on the correct site before downloading.

But here's the problem. Fake, malicious files are spreading online. You might think it's a PDF or MP3 file but it's really a virus. Click here to make sure you don't get caught by this attack.

3. Have security software installed. Security software is designed to catch viruses that invade your system. Your best bet for safety is to ignore malicious PDFs, but if you do accidentally open one, you want the extra line of defense. Click here to download excellent free anti-virus, firewall and antispyware software.

Following these simple steps will cut down your risk dramatically, but there's more.

You don't have to use Adobe Reader for PDF files. There are free alternative readers such as SumatraPDF and Foxit Reader.

These don't have as many specialized features as Adobe Reader and often aren't affected by the same problems. Plus, they run much faster.

So, you may wonder why PDF files are still in use if they're such a big security risk. Actually, PDF files are a great way to share information.

Any computer can read them, and the formatting doesn't change from system to system like Word documents can.

That's why I use PDFs for my helpful e-guides and e-books. If you're looking to set up a new computer, get started in photography or improve your skills, understand Windows 8's new interface, and many other digital topics, I've got a e-guide or e-book for you.

You can download the PDF file seconds after ordering so you can start learning right away. And, because it's a PDF, you can use it on a computer, tablet or e-reader. Plus, since it comes from me, you know it's virus-free! Click here to browse the library of digital information I wrote just for you.

If you're looking to create your own files to share or sell online, you might consider using PDF files as well. I have some great tools that will get you started.

Easily create PDF files from any document using this simple, free PDF printer. Or take your PDF files to the next level with this more powerful creator.

Need to edit an existing PDF? LibreOffice's free PDF Import feature helps you do just that.

Have several PDFs you need to merge into a single file? Click here to make it a snap.

Of course, these are just a few of the many helpful tools I have available to download on my site. And they're all free! Check them out.
