Hello, I´m currently using Comodo Internet Security (with Defense+ in safe mode), Sandboxie (registered version), and Avira Personal. The sandbox is automaticly emptyed when i close the browser (i use Opera or IE). However it seems that a particular adware tracking cookie can always bypass sandboxie... is called "firstname.lastname@example.org" and is located in "C:\Documents and Settings\AlexC\Cookies\ Take a look: http://img44.imageshack.us/img44/562/screenshot002kzp.jpg Concerning to sanboxie configuration, i only allow direct access to Opera bookmarks. I don´t allow direct access to cookies. So, how can this tracking cookie bypass sandboxie Thanks.
