I'm going round Saturday afternoon to see what I can do to remove them. He says he's tried but it reappears. So whether it's a persistent item or he's continuing to use the software that originally put it there I don't know.
There's a fair bit about it on the web and I've now got various things to try. Wondering if anyone here has any experiences of it and removing it?
Also wondered whether it propagates itself to other PCs on the network? Thinking about the laptop and whether if I connect my netbook to his network I risk getting ALOT installed?
