IE6 hijacked - spybot cleared system but start buttons don´t work

[Ron Wolpa]

Some days ago my IE6 was hijacked.
Spybot scanned and cleared the system , lefting as start page a blank;
However the buttons that configure the start page kept disabled ;
By editing manually the register (HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main)
I was able to change start page.
Ive turned register upside down and have not discovered a way to recover the start buttons normal operation.
Does anybody know the right key , if there is one ??
Cheers
