Hi Kathy:
DEP errors in Internet Explorer can be caused by add-on or extensions. Have
you installed any add-ons to IE lately? More about add-ons at
http://windowshelp.microsoft.com/Win...f9b7e1033.mspx
As far as making the DEP errors go away, Help suggests: If you have
recently installed a program and notice DEP closing Windows-based programs,
check with the software publisher to see if there is an updated,
DEP-compatible version available, or try uninstalling the program.
You can also try Problem Reports and Solutions in Control Panel to see if a
fix from Microsoft is available. Open Problem Reports and Solutions by
clicking the Start button , clicking Control Panel, clicking System and
Maintenance, and then clicking Problem Reports and Solutions.
If neither of those options work, you could try using System Restore and
choosing a date before you started receiving DEP errors.
Hope this helps, let us know, thanks.
