haker0 "we don't have an ETA for a vista compatible version of PG2
yes we are hoping to have it done soon but there have been delays because of complications with the driver
for now you can use the 9X version because it is better then nothing but it only blocks TCP connections
the Vista OS has not even been publicly released yet so any user that choses to use it should expect some incompatibility
users cant expect applications for an OS if the OS itself is not even ready yet"

B.I.S.S. Blocklist Manager v2.6.5 BLMInstall265.exe Is compatible with windows vista with no problems.
B.I.S.S. Protowall 201B9_18apr06_beta is only vista compatible/functions only after a fix is applied. Only drawback is logging of blocked ip's isnt visible but protowall does block ip's that are imported from b.i.s.s. blocklist manager. Suggested Protowall Fix is here which shows how to disable ipv6.

Kaspersky Internet Security v6.0.2.614 installs and works great. Needs the Kaspersky Vista patch downloaded from the Kaspersky site
http://www.kaspersky.com/productupdates?chapter=186437046
Updating through an already installed Kaspersky doesnt work properly. Also May need to go into Settings Anti-Hacker/Zones tab and untick Internet Stealth mode setting for some p2p software to connect properly.
Tor & Privoxy & Vidalia bundle installs and works properly.
