Ok, don't worry about the RUN/Runonce dirs in the reg, there's no problem with it, only programs I want to load there.
Ad-aware removes correctly the spyware, I know that sometimes it ask to reboot to del a used file, but not with this spy...
Right now lop is NO more on my pc, it just came back running the unistaller (woody thanks for help anyway...

), the only thing is that button which remains greyed even if lop is gone.
I set the homepage by the reg key if I need to change it, but I want my button back.
In HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre
ntVersion\Policies\Explorer can't find such key or similar.
This is all I have:
ClearRecentDocsOnExit
NoChangeStartMenu
NoCommonGroups
NoDriveTypeAutoRun
NoRecentDocsHistory
NoRecentDocsMenu
NoSMhelp
NoSMMyDocs
NoStartMenuSubfolders
NoTrayContextMenu
