SpywareBlaster's primary protection is that it disables a list of known spyware related ActiveX controls by simply setting the "kill bits" (flags in the registry) for the specific items it protects against.
It works because that is the way ActiveX controls are designed. If the kill-bit is set in the registry, the associated ActiveX control can not run on the system.
So, there is no need to leave SpywareBlaster running. Simply check periodically for new updates, say once a week, and that's it.
I installed Spyware Blaster but how can I be sure its always running? Is there a way to check this? I know I always have to open the program to check for updates.
