Ciao a tutti, ho un problema con la pagina iniziale di internet Explorer. Forse scaricando qualche programma è cambiata la pagina iniziale e quella attuale è il motore di ricerca di Yahoo. Voglio cambiarla con quella di virgilio ma non me la fa cambiare. Ho trovato nel registro la chiave riferita a questa pagina denominata start page Yahoo ecc ecc. La elimino me la fa eliminare ma subito dopo si riforma e quindi non mi fa cambiare la pagina iniziale. Ora come posso eliminarla definitivamente? Ho provato con malwarebyte con hijak this con adw cleaner con cc cleaner con l'antivirus di Windows 8. datemi per favore una soluzione per risolvere il problema. Grazie

Sarai incappato in qualche adware dirottatore, dal browser vai in gestione motori di ricerca, seleziona Yahoo e lo rimuovi, se vedi anche qualche motore di ricerca che non conosci, eliminalo, controlla anche fra i componenti aggiuntivi se c'è qualche componenti sconosciuto e lo disattivi.
ADWcleaner di solito li elimina, dopo la scansione hai cliccato su clean.
Prova anche con questo:
Fai questa scansione:
Scarica JunkerRemovalTool da qui: http://thisisudax.org/downloads/JRT.exe
Una volta scaricato chiudere tutti i programmi e il browser, per evitare conflitti disattiva momentaneamente anche l’antivirus, lancialo cliccando sull’eseguibile.
Per Vista win 7 e win 8 clic col destro sull’eseguibile ed Eseguire come Amministratore.
Appare il prompt dei comandi, premere un tasto per continuare e il programma inizia la scansione, può durare diversi minuti, lascia fare senza toccare nulla anche se sembra fermo, alla fine appare il Blocco Note col log, JRT.txt copialo e postalo qui.
Posta anche un log di Hijack This che controlliamo, ci sarà anche qualche servizio da disabilitare. Ciao
