Firstly, thanks to those taking an interest in/wanting to help with this. Mike, the other applications running are avast home, SpywareTerminator, Comodo Memory firewall, and the Secunia PSI software inspector. All are up to date/latest version. The firewall I was using was CFP 220.127.116.119. (I got a little annoyed with it when it updated via its' own updater, failed to save any settings, then prevented- without any prompts- Limewire and Firefox from connecting to the www) No Threatfire/other HIPS etc installed. I do use the MVPS hosts file. These applications work well with each other, without conflict. Even when Comodo's HIPS (defense+) was active - despite my selecting it off at initial installation. I've installed other security software at times, too, and not had a compatibility issue. I have AVG AS, SAS, A2, Spybot, and Cureit as demand (second opinion) scanners. None have found anything, recently. I have seen new software do a bit of an "I've just installed" dance before, (expressive term) but nothing like this, especially after two reboots,and it does make me wonder about the possibility of a driver leftover somewhere, as Diver suggested.
