I cleared my Firefox betaone cookie, restarted and brought up the site; NOD lit up again, this time with a different trojan name. I made a nonsense of capturing the screen so can't be more explicit - sorry.
Most worrying, I saw a reference to Paypal (bottom left of the screen) before I got to B1. Don't know if it was loading the Donate button or up to no good!
NOD terminated whatever was going on and asked me to submit the trojan, which I did.
Having spent most of yesterday morning scanning with Defender, Counterspy and NOD, I am confident NOD is keeping me clean - but it's quite an exciting ride to B1 these days.
