Browser Hijack

[smoosh]

I just upgraded to Windows 7 when going onto google then going to a link it then goes to another location.  when running combofix and malware bytes then avg nothing found but still same issue even in safe mode.

I have run hijackthis but and went through the self help but cant see anything that would cause this I am not even sure how this has got on my computer as all I did was upgrade to windows 7 it is a real copy and real key used.  My brother was on computer so might have been on some sites?

Any help thanks

Update

I thought I would check the host files when trying to acccess these I could not.  I managed to copy for another computer the host files and then run another scan it then managed to fins a fake svhost now removed and computer working again.

Sorry I thought this was fixed but some times I still getting a pop up from site that dont have pop ups.  I have scanned again but found another host file its almost like when I remove it manages to re add itself?
