Ciao ,

http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=344&SH=N

apri HIJAC THIS ed elimina come indicato in questo articolo

==================================

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.
