Data Execution Prevention Error After Internet Explorer (IE) 8 Upgrade

This was really driving me nuts and almost caused me to completely switch to Chrome which I use from time to time. Here’s how I resolved the problem. As soon as I would launch IE 8, the Data Execution Prevention (DEP) dialogue box would pop up. I would hit OK and then it would shut down IE 8. I tried disabling DEP for Internet Explorer but this still happened at first about 50% and then almost 100% of the time. I even tried uninstalling the MSJVM. None of this helped.

I noticed that if I did not clear the DEP dialogue, I could move it out of the way and open another tab in IE8. I could also select Tools, Manage Add-Ons. I then disabled most of the add-ons (ones I didn’t really need or didn’t even know were there). That did the trick.

Hopefully this will help any other unfortunate souls out there with this very annoying problem.

    Dude thanks so much I thought it was IE8 that just sucked causing all the problems and I too went through all that. My homepage was youtube.com so everytime I tried to view videos it would eventually fail on me. I’ll try out your solution since DEP can’t be removed. Thanks again.

    Thanks much for this post! I’m having the exact problem you describe and will try your fix just as soon as the computer with the problem finishes reboot. :-p

    Okay…. fixed!

    control panel/internet options/advanced/resey inertnet explorer settings

    Part of the process disables addons… job done!

      Thank you, NickV! This worked, and if I can do it, anyone can – I’m an accountant, not an IT wizard! ;-)

      I am copying your solution here so the next frustrated non-coomputer person will see it before they stop scrolling down the list.
      Thank again,

    After I installed the Google Toolbar with IE8 (the released version), I am getting a data execution prevention notice that says IE 8 must be closed. This happens when I click on a link that is supposed to open in a new tab; e.g., when I hold down the Ctl key while clicking the link. Usually, when I close the error box, the link opens, but in a new IE window, not a new tab in the existing window. On occasion, nothing happens. Then, if I repeat the Ctl click, I may get a new tab, I may get an error message and a new window, and I may get an error message and no new tab or window. I tried using the “turn on DEP except for” IE 8, but with no help.
    Uninstalling Google Toolbar for IE 8 seems to have fixed the issue, but now I am left without the Toolbar, which I have come to find essential.
