Annoying Internet Explorer 9 crashes! Possibly DEP?

  1. Didn't know where to post this, sorry if it's in the wrong topic.

    Yes I am an I.E. fanboy so no I won't try firefox or anything else... JUST YET.

    Ever since I installed I.E.9 I get unexpected I.E. shutdowns whenever an ad video or some sort of multimedia is displayed on a webpage. It occurs on what I call "trusted" sites - ESPN, NewVegas Nexus, or even when I am trying to stream live radio!

    The reason given is DEP (Data Execution Prevention). My OS is WIN7x64.

    Control Panel>System and Security>System>Advanced System Settings>Preformance>Data Execution Prevention

    Is it ok to uncheck DEP and see if this solves the problem? Any other thoughts or suggestions?

    No, leave DEP on. This is a quote from Wikipaedia about DEP

    It notes that DEP is not so much preventing damage to your system, rather it is preventing 'buffer overflow' exploits from malware (some, anyway). Most normal software has been updated to prevent that already, without need for DEP, and that wouild include IE.

    Consequently, that you are getting such messages implies some 'add-on' to IE is trying to do that illegal thing, and the most obvious reason would be it is actually malware. It could be such things as infected java, executable active X, video displayers like flash player, extra toolbars, animated mouse pointers, stock tickers, and pop-up ad blockers and so forth.

    Your first step would be a thorough search for malware - see the malware forum on this site. Secondly, make sure all software associated with IE is updated to the very latest version. A highly-respected application for that job is Secunia PSI

    Oh man, thank you for the speedy repsonse! I'll get cracking! The first thing I thought of was an update to IE9. Next, I think my PC is clean. I have used your "5 Step Process" before. I will check again.

    Sucks to want to view a webpage only to have it close because of some stupid video ad!
