Risks from active content
ActiveX controls and Java applets are called active content because they can do more than display text or graphics. Most active content is safe. Common uses of active content are popup menus and
Both ActiveX and Java are supposed to be safe to run in your browser. ActiveX uses a system of digital certificates that lets you decide if you want an ActiveX control to run. Digital certificates appear as dialog boxes that ask if you want to install and run a control that appears when you are browsing the Web.
There are several problems with using digital certificates. Some controls do not have certificates, and some certificates provide very little information about what the control does.
The Java sandbox was designed to prevent Java applets from accessing information outside of the browser and doing anything that might harm your computer. However, hackers continually find ways to get around Java safeguards and use Java features in ways not conceived of by its developers.
