Thanks, all of you, for the prompt and useful help notes - I'm sorry I'm so late in posting a "thank you", but yesterday's radiotherapy ran on a bit late, so I didn't even crank up my computer when I finally reached home!
So now my AdAware is up-to-date with the latest ref file, and I'm still mentally debating whether to remain with the cydoor version of eDonkey, or incorporate one of the options. I think another couple of days' evaluation might be the best course, and then decide which version to use should I decide to retain the services of the Donkey.
Meanwhile, once again, thanks fellas!
