ZoneAlarm seems to work ok. They have a free version. Hopefully, here is their site and here is the link to a free version. If you choose it they nag you a bit to upgrade. If you look around the rest of download.com you might get a few more ideas.
[Martha Farquar] Hm. Now I come to inspect the games, you haven't been seen for a while at Dan's. Or here for that matter. At any rate, posting this here too. If you still have a working email address, maybe you could mail me it.
If you're wondering why I was a bit quiet yesterday it's because I was at Alton Towers doing silly rides involving me being turned upside down, generally spun about, dropped into a hole, gliding on my back and, much to the amusement of the rest of the party, getting extremely moist and clammy on the rapids. Great fun, and I note the Bloboscope has taken off with some alacrity. Marvellous.
[rab] I was going to furcate a while ago - but then discovered that I had things to do that were a little more pressing. If I find I have a spare hour I'll do what I can - but my psychiatrist has only just signed me off as clear of the nightmares caused by Acre Street, I'm not sure that dragging it all up again would be too wise. But then I'm not - wise that is.
