Well, following the comments earlier on this thread, I also downloaded the windoze software. It found one bit of spyware that my Adaware SE hadn't found. What annoyed me is that I paid for my Adaware SE to get Adwatch which I have been very impressed with so far.
I was pleased to note that Microsoft considered my XP pro legal (which it is) and having downloaded the software, copied it onto the other computers on my little network (also using legal copies of XP) and successfuly installed it on them.
I have now at last obtained the latest Adaware update which, on running a scan showed that adwatch had successfully kept all Adaware's list of nasties out of my computer.
I suppose it will be back to this and Spybot when Bill starts charging for his antispyware stuff
P.P.
