Forgive my ignorance but I have a couple questions. I use IE8. Recently I was looking in to some problems I am having with websites displaying properly and getting Unknown Zone (Mixed) for security zones. I was led to Restricted Sites and had to remove a site *.doubleclick.net related to AdSense. Websites were now displaying properly but I was still occasionally getting Unknown Zone (mixed). When I opened SpywareBlaster I was told I had 1 item disabled in restricted zones. So I reeneabled all protection and my problems returned. So again I removed *.doubleclick.net from Restricted Sites and all is good. Can I remove doubleclick permanently from SpywareBlaster? What about my Unknown Zone (Mixed)? Are there other sites in Restricted Zone that are causing it?
