2$,
Thanks for the page- but- went onto this website, downloaded a programme called Spycatcher, which appears to be similar to Spybot, ran it, went to get rid of the nasties that it found, to be told it was only a trial version, and I'd have to buy the "full" version to get rid of them!
If it had stated that before I wasted my time, I would have been more sympathetic. However it has just been unceremoneously uninstalled!
Thanks anyway.
