Something like ? If so then check the DNS settings on your PC - esp hostname and domain. Also try disabling any proxy webservers if you've one configured.

So in other words they have put what amounts to an unwanted virus on my machine

Hmmmm.......wonder why that was never mentioned in the reply to the small rant I sent them (where I was left with egg on my face after stating as far as I am aware, u guys aren't hosted by them....when u are)

I'll look at their site then

EDIT - Been on their site and I can't find anything about shells or uninstalling them. I don't even remember installing the thing in the first place, but then again this evil spam tool which now seems intent on blocking me from my own homepage (the only palce it's doing it now) probably doesnt want you to know anyway.

EDIT EDIT - Well, this seems suspicious. Looking through my Internet Options, I found an option called 'Use third party browser extensions' and I thoguht maybe that enables this dodgy thing popping up the 34sp crap. And you know what? It stopped it. Suspicious indeed.........
