If you are trapped on a page with Security Error Code 0x80070424 as the title, here are a few tips on how to get out of it on Internet Explorer.
Things You Need
* Knowledge of Internet Explorer
* Local Administrative Privileges
Desktop
On a desktop computer with Internet Explorer as the browser, you will need to disconnect the Ethernet cable from the back of the computer or the wall jack if the desktop computer is in a locked podium or the rear is difficult to reach. Once the Ethernet cable is disconnected from the desktop computer, the web page will not have a chance to refresh the content from the Internet (thus causing an HTTP 404 Error) and this will end your session to allow you to close the browser or tab with the rogue page.
Laptop
On a laptop computer with Internet Explorer as the browser and using a wireless connection, you will need to disable wireless using Control Panel or WiFi switch (if equipped) on the front or side of the laptop. With the laptop disconnected from the Access Point, the webpage will not have a chance to refresh the content from the Internet (thus causing an HTTP 404 Error) and this will end your session thus allowing you to close the browser or tab. If the laptop can access the Internet over an Ethernet cable, please disconnect the Ethernet cable from the laptop as well.
Prevention
To prevent this from happening again to you, look to alternate browsers and use these for surfing the Internet and save Internet Explorer for the Intranet programs at your company or for your online banking as alternate browsers have a feature to prevent a web page from creating dialog boxes over and over. For a list of free Internet browsers, check on your favorite Search Engine then download from their official site to prevent yourself from adding threats on your device. Keep in mind, you may need to use the an Administrator account since the install will affect all users.
