John, and Maclover2000

I have used Zone Alarm (free), Sygate firewall (free) and now am using Outpost (free version 1.0). I have tried others and have found that Outpost works just great with Avast. Have not had any problems with this combination. I have been using Outpost for about 5 months with a couple of different Anti Virus programs thence am down to just using Avast as I believe it offers the best protection. ;D Of course this is just my opinion and there are alot of those floating around. ;)I use Win Me btw.
