Safari closed by Windows XP security

Question

Data Execution Protection of Windows XP continues closing Safari even after to be included in the exceptions' list. Please, give me some idea to stop or close the security program, or how to fix the issue. It's not permanent, sometimes opens fine and others don't. 

Answer 1

Okay ... so not the "misplaced old" QuickTime componentry thing then.
I think we'd better try scraping out and replacing your "proper" QuickTime componentry, just in case that's the source of the problem here. (Both Safari and Firefox use the same plugin files from the QuickTime program files, so if the QuickTime program files are damaged in the right/wrong way, that can cause trouble for both applications.) We'll also take a few other explicit precautions with the reinstall, just in case.
Best to print out these instructions, because at one stage of proceedings you won't be able to use a web browser.
Preliminaries
Download and save a copy of the QuickTimeInstaller.exe installer file from the Apple Website. (Don't run the install on line and don't start the install just yet. Get the installer that doesn't mention iTunes. If you discover you've accidentally downloaded an iTunesSetup.exe instead of a QuickTimeInstaller.exe, go back and download the other option.)

Quit iTunes and/or Safari if you have them running.
Uninstall phase
Head into your Add or Remove Programs Control Panel. Uninstall QuickTime. (From here on out you won't be able to open iTunes until we get QuickTime reinstalled.)
Next we'll remove any leftover QuickTime program files or folders.
In My Computer open Local Disk C:\ or whichever drive you've got your program files installed on.
Open the "Program Files" folder.
Right-click on the "QuickTime" folder (if it still exists) and select "Delete".
Go back into Local Disk C:\ or whichever drive you've got your operating system installed on.
Open the "Windows" folder.
Open the "system32" folder.
Right-click on the QuickTime.qts and the QuickTimeVR.qtx files (if they still exist) and select "Delete".
Empty your recycle bin and restart the PC.
Reinstall phase
After the PC restarts, do not open any applications. Disconnect from your network and/or the internet. Now switch off all your security software (firewall, antivirus, antispyware).
Now start the QuickTime reinstall by doubleclicking the QuickTimeInstaller.exe file you downloaded earlier.
Re-enable all security software prior to reconnecting to the internet and/or your network.
Does the QuickTime reinstall seem to go through okay? If so, does Safari launch properly again?
