Hi everyone,
I recently installed a (free) Firewall on my PC at home to guard against raids on my computer while connected to the net. I did this after getting a Trojan Horse virus on the day jobs laptop.
This prompted me to worry about the Classical Gas machine in the dinning room. I read an article in a magazine about a free software firewall called Zone Alarm.
I downloaded and installed it and it works. It's quite frigtening to see the warnings come up when another computer tries to break into my system and Zone Alarm blocks it.
You can find out more information and download the free version at http://www.zonelabs.com/products/za/index.html
I would advise everyone to look at this.
Michael
