DEP problems

[Jim]

For some unknown reason, Internet Explorer has ceased to function. Reason:
DEP keeps the program from loading. I get a warning box telling me that DEP
has shut down Explorer to protect my computer. I am running Vista Ultimate
and have had no previous problems. Appreciate some guidance. Thanks.

Almost certainly a bad add-in.

Well, would you leave us a bare memory dump of the crashing situation
through the System Failure settings?
Most likely it is a bad DLL file gets loaded by the IE or a bad
'callee' function, because of installing toolbars or things of that
sort. If it was the case, check the situation farther by using Process
Explorer (from sysinternals).
