In Spybot Search & Destroy... What is "Immunize"...??

Question

Has cookies, images, installations, domains... etc.. from Firefox and Internet Explorer... and at the top it says 138,336 Unprotected... 0 Protected..

What is that?

Answer 1

It gives your browser access to Spybot's database of untrustworthy sites. It allows your browser's security to better identify possibly harmful sites and prevent them from installing malicious software on your computer.

When it says "138,336 Unprotected... 0 Protected" it means that you have not run the the part of the program that tells your browser(s) about the untrustworthy sites. Simply click the "immunize" button, with the green cross, to make that work.
