Been using/beta testing for the developer since around version 1.7. IMHO a brilliant little security app. A 250 kb download, a meg installed and offers protection against any and all internet/browser exploits, zero day included, without the need for any blacklist data base updates. Takes a bit of user input but becomes second nature after a bit of use. Also has a great support forum where you can post as a guest without the need to register.
