Notice from Data Execution Prevention

I'm running IE 9.0.8112.16421 and today I saw something I've never seen before. The notice read:IE has closed this webpage to help protect your computer. A malfunctioning or malicious add-on has IE to close this webpage. What you can do is: Go to your homepage; Try to return to the page you were viewing; More Info.

I chose More Info and saw this: Data Execution Prevention detected an add-on trying to use system memory incorrectly. This can be caused by a malfunctioning or a malicious add-on.

I opened IE and checked the currently loaded add-ons.The list follows:

ShockwaveFlash Object.
Windows Live ID Sign-in Helper
ie Spell and Options
Lexmark Toolbar: Listed twice, once as the Toolbar and next as the helper
Java Plug-In SSV Helper
Java Plug-In 2SSV Helper
RoboForm Toolbar and Toolbar Helper
Simple Adblock Class
WOT (Web Of Trust) and it's Helper

Other than running IE wihout any add-ons and adding them back one at a time, is there a less tedious way of finding the guilty one? Could that notice have been a one-time occurrance? Has anyone ever seen the same notice?

Logicearth, I was on Jacquie Lawson's website, I send greeting cards from there. It's not a free program, you have to become a paying member and it does use Flash, as her cards are animated. I've sent her cards for over a year with no problems.

Clear up something for me. Are you saying the card site must have done something wrong or Flash could be the culprit?

Please answer all my questions.

No ads there. when you pay your money you don't get that kind of stuff. I hope someone replies that knows what I should do. Maybe I should just ignore that notice, I've had the same add-ons for quite some time with no problems.

Thanks for trying.
