Ciao pietro,
esegui queste operazioni

1) Disattiva il ripristino di configurazione, leggi qui come fare
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=257&SH=N

2) riavvia in modalità provvisoria, leggi qui come fare
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=344&SH=N

apri HIJAC THIS ed elimina come indicato in questo articolo
http://www.aiutamici.com/software/descrizione.asp?CodSw=1175
le righe che seguono, (nel caso le righe da eliminare non compaiono in modalità provvisoria, eliminale dalla modalità normale e riavvia il computer).

==================================
C:\WINDOWS\System32\Yahoo.exe
C:\WINDOWS\SYSCFG16.EXE
==================================

Con la funzione TROVA di Windows, cerca ed elimina questi file,

==================================
Yahoo.exe
SYSCFG16.EXE
==================================

al termine utilizza i programma AD-AWARE e SPYBOT indicati in questo articolo
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=388&SH=N

sempre in modalità provvisoria fai una scansione Antivirus

quindi riavvia il computer e controlla se il problema e risolto, se e tutto OK riattiva il ripristino configurazione disattivato all'inizio di questa procedura.
