Data execution every time i close my internet, i have the data execution pop up. i have to go through the task master to shut down the internet explorer.

DEP (data execution prevention) attempts to separate "data" (such as the text of a webpage) from "instructions" ("move the string 'abc' to locations '12345/12346/12347'"), to prevent computer-hackers from introducing "data" (downloaded from a maliciously-constructed web-page) into an area marked as "instructions". The "threat" here is that the "data" will actually be "instructions" of the hacker's choosing, thus giving the hacker a chance to run instructions to completely "take-over" control of your computer.

Click "Start"
Click "All Programs"
Click "Accessories"
Click "System Tools"
Click "Internet Explorer (no add-ons)"
Do some web-surfing.
Close Internet Explorer.
If it closes "normally", then one of the "add-ons" that usually is loaded when Internet Explorer starts is causing the DEP exception.

Start Internet Explorer.
Click Tools
Click Manage Add-ons.
Choose one "suspicious" add-on, and "disable" it.
Close I.E.
If it closes normally, then that add-on should _stay_ as "disabled".
