Your application files are corrupted!

Question

I recently purchased a new MacBook Pro.  I also have a three year old MacBook Pro that the new one is replacing.  When the new one was removed from the box, it was running fine.  It also asked me some questions concerning it being a replacement, so I said 'sure' and it wanted me to run the Migration Assistant.  So I ran the Migration Assistant for the next four hours.
When it was completed, it said everything was copied successfully.  Now, whenever I log onto the new MacBook, I receive the following error message:
"Your application files are corrupted!  For security reasons please reinstall the application."  Then there is an OK button.
I have tried reinstalling the application files (I think).  Also, it only happens when I logon.  So, I made a new account thinking the account may be the problem, but the new account shows the same error message.  I tried holding down the Shift key until the progress bar appeared, but still no luck.
The old MacBook ran, or still runs fine and error free.  What is my next step?
Thank you.

OS X Lion and later let you:
Start from OS X Recovery using your Time Machine backup disk. With OS X v10.7.3 and later, Time Machine backs up the Recovery System on your Mac to your backup drive as well. This lets you use your Time Machine drive to start up your Mac if needed.

OS X Internet Recovery
Mac models introduced after public availability of OS X Lion include the ability to start up directly from an Internet-based version of the OS X Recovery system. OS X automatically uses this feature when the Recovery System on the hard disk isn't available (such as when your hard disk encounters an issue, or when your hard disk has been replaced or erased). OS X Internet Recovery lets you start your Mac directly from Apple's servers. Starting up from this system performs a quick test of your memory and hard drive to check for hardware issues.
OS X Internet Recovery presents a limited interface at first, with only the ability to select your preferred Wi-Fi network and, if needed, entering a passphrase. Next, OS X Internet Recovery downloads and starts from a Recovery System image. From there, you are offered the same utilities and options as a local Recovery System.
Requirements for reinstalling OS X using Recovery
Reinstalling OS X using OS X Recovery requires broadband access to the Internet via Wi-Fi or an Ethernet connection. OS X is downloaded over the Internet from Apple when OS X Recovery is used for reinstallation
If you use Internet Recovery to reinstall OS X, it installs the version of OS X that originally came with your computer. After installation is finished, use the Mac App Store to install related updates or later versions of OS X that you have previously purchased.
