Hi Caroline,
The most likely cause is an activeX component that has been added in the
last few months, i.e. google toolbar or some other small app like that. DEP
is designed to protect your system, so turning it off isn't such a good
idea. The best way to solve such issues is to identify the rogue add-on, but
first, let's see if the problem occurs when no add-ons are enabled. You can
start IE with no add-ons by:
1 Press the 'windows key' and go to 'all programs';
2. Go to 'accessories' and open the folder;
3. Scroll down to 'system tools' and open that folder;
4. Scroll down to 'Internet Explorer (no add-ons) and press the 'enter' key.
IE should work just as before, but without add-ons. Use it in this mode
until you are sure that the problem has not occurred again - I don't know
how long it takes for the DEP error to pop up, but try it for as long as it
takes. If it doesn't occur in this mode, then it is probably an add-on that
is causing the problem.
Try this first and, if the problem is resolved, then we can start a process
of disabling each add-on in turn until the rogue add-on is identified.
John.

Subject: [access-uk] Data Execution Prevention
Hello,
I am using a Vista laptop and IE9. Recently I have started to receive a
message while browsing that a data execution prevention error has occurred
and IE has had to close to protect my computer. If I re-open the browser,
it continues to work properly for a while and then the same message could
appear again. It can occur on any page, sometimes when I'm on Amazon, eBay
or other similar sites which I wouldn't expect to cause any problems.
I have googled the problem and have found a solution, but I'd like to know
whether it's advisable to follow the recommendation or if I could be opening
up my PC to trouble. What has been suggested on several sites is to enter
the following into a command prompt running as administrator:
bcdedit.exe /set {current} nx AlwaysOff
I have already verified that DEP is set to "Turn on DEP for essential
Windows programs and services only".
If the suggestion isn't recommended, please could anyone give an alternative
I could try. This laptop is four years old and has only been coming up with
this problem for the last couple of months. I haven't installed any new
pieces of software which I would expect to have a bearing on it.
Thanks for any help.
Caroline.
