why do i keep getting DEP error message each time i close IE8 or a tab?


windows xp has DEP ( data execution prevention ) some viruses etc use that sort of technique and from SP2 onwards I believe it was they included it.

http://www.zensoftware.co.uk/kb/article.aspx?id=10002


Several OSs have no-execute or execute protection. Microsoft has added this as well in SP2 with data execution prevention (DEP). This precents code execution in memory regions already marked as storage. This is a powerful tool against buffer overrun exploits. If a program is failing and you want to disable DEP to see if that is the cause. Here are the steps. (Just disable DEP for the program in question… don’t disable it for your whole system.)
    1. Click Start
    2. Select Control Panel
    3. Select System
    4. Click the Advanced tab
    5. In the Performance region select Settings
    6. Click the Data Execute tab in the dialog box that opens
    7. Select Turn on DEP for all programs and services except for those I select
    8. Click Add.
    9. The open dialog box will open. Browse and select your application.
    10. Click Open
    11. Click Apply
    12. Click Ok
    13. Reboot
