Hi Paracab,
Good luck with your defences!
I wasn't aware of what could possibly be going with my computer without me even knowing about it and I am amazed that broadband service providers do not insist on you having adeqaute protection before you have broadband.
When I had Broadband installed (not BT, btw), the company would not install the connection and cable modem without a PC to connect and "test" the internet connection. They would not install and then connect to the firewall / wireless AP / switch I had ready. They coc*ed up trying to get a USB - Ethernet connection to work (I was at work, unfortunately) despite being given instructions to use the (obvious) ethernet cable left dangling for the purpose, necessitating the removal and re-installation of the TCP/IP stack by me later that day.
When they returned to try again, I had set up a "sacrificial" W2K desktop for them, which (to be fair) they completed the installation on. But that PC was well and truly compromised once it had been on the internet unprotected for a few hours!
So do not hold your breath for the ISPs to insist on security. Shoelaces appear to be a challenge for some of their operatives.
Somewhat jaundiced,
