I have been reading this mailing list for several months now, and I haven't "heard" about a "personal firewall" (for Windows) with the amount of options and features of AtGuard. I still use AtGuard at home and work and I really really like it but I don't know what other options exist in case in some other version of Windows it just stop working...
I know Symantec bought the "technology" :-( , but I don't see the same power in their software... katarn.
