Spybot's Immunization is passive protection, meaning it does not run in the background. When you "Immunize
", entries are added to Windows registry
which blocks the storing of cookies
from some sites and a large number of sites are placed in the restricted zone, by domain (site name) and by range (IP address).
A better alternative is to use SpywareBlaster
which does the same job on a larger scale...places sites in the restricted zone, all by domain (site name), prevents the installation of ActiveX and more. In previous versions Spybot would tell you if SpywareBlaster was installed on your computer that it offered more control over your settings by letting you add and remove sites very easily.
Further, Internet Explorer 8 and above uses the SmartScreen Filter which provides similar but more comprehensive protection
by identifying and blocking sites on the web that are distributing malicious software. It is kept current in an Internet accessible database, so it can be much larger and more quickly updated than a local static list that is only updated periodically.
