Hi Nganvu.

No, they are differnet.

Spyware blaster's snapshot basically takes an 'image' of your web browsers settings.

So if you are infected with spyware, spyware blaster can restore your settings to a know suitable point.

You should run Spybot, Adaware and HijackThis before. If they dont get rid, then you could try to restore from Spyware blaster.
