Internet Explorer has closed this webpage to help protect your Computer

While open a web page it may shown the error as "Internet Explorer has closed this webpage to help protect your Computer"

Solution:

Goto Internet Explorer -> Tools -> Internet Options -> Advanced -> Scroll down to Security -> Uncheck “Enable memory protection to help mitigate online attacks*”

Close all browser windows and restart the browser. The issue should have been fixed 

Edit: Alternatively you can use either of following 2 alternate solutions.

Alternate 2:

Open registry using start->Run->regedit->ok

Go to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Internet Explorer >Main

On the right hand side you will see a DWORD key called DEPOff. IF this is set to value 0, just change it to 1 and close registry editor.

• Restart Internet Explorer and check if the problem has been fixed or not.

Alternate 3:

Right click on My Computer->Properties (or start->Run->sysdm.cpl->ok)

• Click on “Advanced” Tab. Click on “Settings” button next to Performance.
• Click on last tab “Data Execution Prevention”
• Select Second option and then select “Internet Explorer” from the bottom panel.

(If “Internet Explorer” is not already present there then just click on “Add” and then select “c:Program FilesInternet Exploreriexplore.exe”)

Click OK and restart internet explorer. The problem should have been fixed.
