After a long silence, Microsoft is finally shedding some light on Internet Explorer 8. The company says it plans to have a beta version of the Web browser available during the first half of 2008.

While Microsoft claims it is impossible to keep multiple versions of Internet Explorer on the same machine, some hackers have successfully separated several versions of Internet Explorer, making them standalone applications. These are referred to as "standalone" IEs and have included versions 3 through 7.

One of the biggest security problems in previous versions of Internet Explorer was when malicious Web sites used ActiveX controls to steal information or to wreak havoc on the victim's system. There are actually a whole group of ActiveX controls that come with Internet Explorer and that are enabled by default in previous versions of the browser. These ActiveX controls were not intended to be malicious, but some hackers have figured out how to use the controls for malicious purposes.
RTI for Internet Explorer is free for noncommercial use and $195 for commercial use. Quantities of 50 or more qualify for a discounted rate of $99. RTI for Internet Explorer requires that a Java Runtime, version 1.4 or 1.5, be installed prior to usage.

The Component Object Model (COM) technology is used extensively in Internet Explorer. It allows third parties to add functionality via Browser Helper Objects (BHO); and allows websites to offer rich content via ActiveX. As these objects can have the same privileges as the browser itself (in certain situations), there is a concern over security. Recent versions of Internet Explorer provide an Add-on Manager for controlling ActiveX controls and Browser Helper Objects and a "No Add-Ons" version (Under Programs/Accessories/System Tools).
