What's the most insecure application on the planet? You'll be surprised.

Think you know which application whose security holes put more people at risk than any other? You probably don't. I've got the answer, plus a list of other programs with security issues.

The security company Secunia has come out with its list of applications which have the biggest issues around the world for the first quarter of 2015, and the answer is clear: the biggest security problem is caused by Oracle Java. Java topped the list of problematic applications in all of the 15 countries Secunia released information on, including the U.S., Great Britain, the Nordic countries, France, Belgium, the Netherlands, Germany, Austria, Switzerland, New Zealand, and Australia.

Secunia arrived at the numbers based on scans of PCs by its Secunia PSI software between January 1 and March 31 of this year. It ranked the risk exposure of applications by multiplying their market share by the percent of machines that had unpatched versions of the applications on them. Unpatched machines are security risks because they are more likely than up-to-date software to have security holes.

The application with the second highest risk exposure in the U.S. is Apple QuickTime, although if you count all versions of Adobe Reader, that app would have a higher risk. Adobe Reader 10.x comes in third on the list, and Adobe Reader 11.x comes in fourth.

Also dangerous are end-of-life programs --- programs which are no longer supported, which means no new patches are being released for them. At the top of the list of those in the U.S. is Adobe Flash Player 16.x.

What does all this mean for you? Patch, patch, and patch again. If you've got Java, QuickTime, or any version of Adobe Reader, make sure to update them. In fact, it's a good idea to patch all your software. It's the cheapest and easiest ways to keep your PC safe.
