In Windows many applications come equipped with an ID number or GUID. This number must be the same across the Internet and your whole system. The problem is that certain people, with bad intentions, can access your PC via this ID and ActiveX or Java applets. To avoid this you need ID-Blaster Plus.
The aim of ID-Blaster Plus is to frequently change the ID numbers of applications, destroying any traces of the old one in your PC, so no-one can use it to gain access.
This way, thanks to ID-Blaster Plus the information stored in your PC is a little bit more secure and protected against external attacks and threats from the Internet.
