Web browsers are capable of parsing active code in many forms, including JavaScript, ActiveX, and Java code. These are automatically downloaded and executed by web browser. Malicious individuals often take advantage of this to attack systems, distribute malicious code, or negatively impact systems. Microsoft Internet Explorer (IE) is installed as a default component of Windows Operating System and is closely integrated with it. Because of this, an exploitation of IE can seriously impact the underlying Windows installation, so it is critical to stay current with all IE updates. IE updates can be acquired through
the Windows Update and Automatic updates features as described earlier.
