Power/restart didn't cure. Unfortunately your message came through as I was having another go at SysRestore, which didn't successfully complete but seemed to cure the problem on the restart so couldn't test the unplug/power exhaust (which I should have thought of, sorry!).
I'm out of my depth with the route print screen but although it contains lots of destination addresses the only gateway shown is 192.168.1.1 which is the router, and in addition 127.0.0.1 appears as an additional interface (which seems right: the software firewall?). I assume this shows the ghost has for the moment disappeared. There's no 10.n.n.n.
