When you begin typing a website address in the address bar at the top of the window, Internet Explorer displays suggestions based on your Favorites and previously visited pages. These suggestions appear on a drop-down menu below the address bar, allowing you to return to a previous page by clicking an address or pressing the down-arrow and "Enter" keys. To eliminate this feature, delete your browser history. Alternatively, prevent Internet Explorer from using the history for suggestions by clicking the gear-shaped button in the upper-right corner of the window and selecting "Internet Options." Select the "Content" tab in the new window and click the "Settings" button under "AutoComplete." Remove the check from the "Browsing History" box and click "OK" in the two open windows.
When Internet Explorer 9 behaves normally, you may see your previously visited pages pop up on the screen if you type an address in the address bar or click the "Back" button. It is possible to trigger Internet Explorer's "Back" function inadvertently using a trackpad gesture or keyboard shortcut. If you see previously visited pages in conjunction with other unexplained behavior, your computer may have a malware infection that you need to remove.
Many modern notebook computers have touchpads that support gesture-based controls. If you are unaware of the gestures your notebook supports, you may inadvertently perform the gesture for the browser's "Back" button, causing a previously visited page to appear. For example, swiping three fingers left on the Elan notebook touchpad causes the browser to move back one page.
In Internet Explorer, pressing "Alt" and the left-arrow key simultaneously causes the browser to move back one page. You might accidentally use this keyboard shortcut while typing, particularly if you use another program that utilizes the "Alt" key for keyboard shortcuts.
A browser hijack is a form of malicious software infection that causes the browser to display pages other than the ones you attempt to reach or utilize a search engine other than the one you prefer. If you consistently see pages that you did not intend to visit and have closed, Internet Explorer may have a malware infection. Install an antivirus or Internet security product to resolve this issue. Microsoft Security Essentials and Windows Defender are two free security tools for licensed Windows users.
