Salve!
Qualcuno può fare un controllo? Questo è il secondo pc di casa, non molto potente, ma ultimamente ha rallentato un po' troppo. Ora ho disinstallato Adobe e installato Foxit, e già va meglio. C'è altro che posso fare?
E poi... a distanza di un anno, Alfonso, sei sempre del parere che è meglio non scaricare Explorer 8?
Grazie!!!

virus non mi sembra di vederne, c'e' qualcosa che si puo' eliminare in quanto inutile pero' meglio che diano uno sguardo i nostri esperti.

Grazie R16!
Ho eseguito tutto (solo non ho cancellato Rainlander perché mi serve che si apra all'avvio).
Da Malwarebites non vengono segnalati oggetti "malevoli".
Riporto il nuovo log: spero che ora vada tutto bene: mi sembra più veloce.

Dimenticavo: visto che Messenger non viene usato, si possono cancellare le voci relative?

E riguardo a Explorer 8 sai dirmi qualcosa?

r16 eccomi!
Ho eseguito tutte le pulizie e la situazione sembra migliorata.
Adesso ho scaricato Explorer 8 e spero che non mi dia problemi...

Intanto GRAZIE e buona giornata!
