Explorer.exe is a trojan I am sure of.

I'd remove

R0 - HKCU\Software\Microsoft\Internet Explorer\Toolbar,LinksFolderName = Hiperligações

Out of time. I'll look at it later feel free to AIM me. But defentaly do a virus scan. and the adaware scan in safe mode. Make sure to use housecall or pandasoft for the scan and not something like AVG.
Good luck
