A potential security flaw in Windows is the ability of Internet Explorer to run Java scripts. A .dll file located in the system folder on the C drive enables IE to run Java:
. . . you can disable the ability of IE to run Java scripts in the Registry Editor under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3
Change the value for 140D at this location to 3. This will cause the execution of the scripts to be disabled by default.
