I have version 3.1 and I really like it. However, I also have firewall protections, IE6 Security, Anti-virus, etc. So I do not know if restricted tracking cookies are being blocked by Spyblaster or another program. It says it still protects even if you shut down the program. Is this true? How is that possible and then why do you have to enable protection when you open up if it is protecting your computer when it is not even running?
