Hi,
I have the same problem with the mysearchnow trojan.
I looked through the answers on these pages and tried to fix it. I managed to get rid of some of it, but my startpage is still hijacked.
Running hijackthis in safe mode i fixed R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://mysearchnow.com/passthrough/i...www.google.dk/, but it keeps coming back.

My log:
