My problem is that the "Data Execution Prevention" screen comes up when I TRY to get into certain programs.  I've tried all the quick fixes on the Microsoft website and nothing is working.  I have only had the computer about a month and I am unable to fully utilize due to this error.  I've reinstalled twice and re-formatted once.  I've spent hours on the phone with Dell representatives and they were no help.  Does anyone have any suggestions that might help me.  I just want to turn the darn thing OFF.
