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.

Free program "Ad-Aware" from Lavasoft clears out all spyware stuff. I've also used the Opera browser with much happiness.

[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.

Thanks all above - Ad-Aware installed and seems to have worked. I've downloaded Opera too, but it isn't working properly yet...

[Proj] I mailed you last night and again just now. NB. I've only played once at Dan's in about 4 years.

[Bob,gil] I switched off all Java and JavaScript on my browser ages ago and it's never inconvenienced me even slightly.
