I have used spybots immunize function and spyware blaster both, but still have questions about immunizing that I'm not clear on. 1. Since spyware blaster and spybots immunize feature adds thousands of hostnames in the host file, which starts at startup, what is the performance impact in general windows use? just a few extra mb ram at startup? 2. What is the browser performance impact? 3. How does spybots immunize function differ from spyware blasters? Which has the larger or better database?
