ActiveX Controls Require Extreme Caution

• Programs installed with ActiveX controls are as varied as the programmers who create them. Public computers often have restrictions on ActiveX controls to avoid the installation of spyware or other malicious programs on your computer. Microsoft explains that installation of ActiveX can stop your computer from functioning correctly, collect your browsing habits and personal information without your knowledge, or can give you content like pop-up ads that you don't want.
  
  

When to Allow ActiveX Controls?

• Allow ActiveX controls only when dealing with a reputable website you trust. Microsoft recommends also checking the website's publisher to determine whether it appears trustworthy.
  
  

Refusing to Accept ActiveX Controls

• The safest decision to make in protecting your computer from hackers is to avoid allowing ActiveX. Worldstart.com explains that you can have you browser set to not allow ActiveX content from sources that aren't marked as safe for scripting. Locate the ActiveX options in Internet Explorer by going to Tools, Options and clicking on the Security tab. Scroll down a little until you see the title "ActiveX." Under this heading, there are several options to disable, enable or prompt controls. Scroll through the list and select which ActiveX settings you believe are safe. Disable those that are not deemed trustworthy. Alternatively, you can refuse an ActiveX control when Internet Explorer displays a dialog box that identifies the publisher and asks if you want to run the file.
