comodo firwall

It is compatible with Windows 7. Officially it is not supported yet but it works all the same. On my 32 bits system I have been using CIS successfully from Windows 7 beta until the current RTM version.

There are a couple of moderators who use CIS with Win 7 x64 .

Of course. Latest version works flawless here on Seven x64.
