strani messggi di errore

[9Fiore9]

ciao a tutti
ho riscontrato dei rallentamenti nel computer e mi sono comparsi dei messaggi strani sostanzialmente di 2 tipi:
1)appena provo ad aprire il pannello di controllo mi compare un messaggio di errore e mi dice che ci sono delle restrizione e di contattare l'amministratore.( nel mio computer c'è solo un utente)
2)ogni tanto quando sono su internet mi compare un mess che mi dice che si stanno eseguendo delle copie di file di registro e che il computer potrebbe essere infetto poi dice fare una scansione.
se si preme si,si entra in un sito dove ti fa uno sca del computer e il 38 secondi ti dice che è infetto(il tempo troppo poco e la finestra che compare non mi hanno convinto e non sono andata avanti)
che devo fare?
mi consigliate qualcosa
grazie a tutti
ciao
