Its nothing that a reformat and reload of the O/S and applications won't fix, sprocket - all my data is backed up externally on CD anyway. The problem is that firewalls and virus protection systems seem to be no longer any use. The morons are attacking directly, infecting the site code itself; code that our browsers necessarily have permission to import into our computers. There is no longer any such thing as a safe site - by the way, I even have java disabled so I don't think that the guilty code was embedded in java script. There was an image file on the site - a map of the country - and it was when the map was downloading that the alarms went off. That may be a clue...
