Spyware problem - Persistent proxy server setting for dial up connection - http://66.230.143.156:80

Hello,

Hello,

I have a problem on a Windows XP Home system. I have cleaned out hundreds of bits of ad/spyware, run Trend Micro Antivirus, Bitdefender antivirus, Adaware, Spybot, Microsoft Anti-Spyware, and all of these tools now report clean. I used HijackThis to clean out other nasties, and the problem persists. I cannot find any reason for the proxy setting to continually return, but it does. If I delete the entries with HijackThis, uncheck the 'Use Proxy' in the dial up settings (it's a Sagem USB ADSL modem - Very nasty!) then I can connect - Once. Then, subsequently the proxy setting has returned. I know this is spyware related, but I cannot resolve it, and I am tearing my hair out. Here is the HijackThis log, which doesn't show anything untoward as far as I can see (The WinMX application is clean):
