Which firewall to use with Bitdefender AV 2010

[zerotox]

Hello, everyone,

I just installed Bitdefender AV 2010. I'm wondering which firewall to install along with it. Have a license for Online Armor and Outpost but have heard that its new version dropped support for Loopback interface. I'm open to trying some of the free ones like Private Firewall and PC Tools. The most important is to be compatible with Bitdefender.

Thank you for your suggestions
