Salve,

Ho installato incredimail ed subito dopo mi ha cambiato la mia pagina preferita nella loro incredimal. e mi ha installato anche come motore di ricerca mystart search.
Non riesco più ad disinstallarla.
Incredimail lo gia disinstallato.
Se avete delle idee aiutatemi.
Grazie, gumita1277

Controlla in installazioni e applicazioni se la barra incriminata esiste.Se hai Ccleaner controlla in Avvio(quella è lista di tutti i programmi che partono in automatico)se Mystart è presente e se lo è togli la spunta nella casella attigua e riavvia il pc la barra non dovrebbe comparire.
P.S.Metti anche un log di HijackThis.

Il log e questo:

Puoi fixare ed eliminare senza problemi tutte le voci che riguardano Crawler e Yahoo, se non sai fixare, leggi la scheda di alfonso. Io ti consiglierei anche di installare il Service Pack 3 e se usi I.E. come browser
predefinito, allora installa anche I. E. 8 che è meglio della vs 7.

Ciao e grazie su interrnet explorer 7 ho risolto, eliminando crawler search dalle opzioni. In quanto per firefox il mio preferito per navigare in internet non ci riesco e rimasto ancora.
Non so dove mettermi le mani per toglierlo.
Quando ho installato incremiail ho tolto la spunta per non modificarmi la mia homepage o il motore di ricerca, però il giorno dopo mi si e modificato la pagina da sola senza accorgermi. Spero che nel mio log di hijack this qualcuno mi dice cosa devo toglere e risolvere questo fastidioso problema.
Grazie a tutti e aspetto le vostre idee ancora, Cami77

Bravissima cami e grazie per la soluzione.Il log a parte le toolbar direi che è a posto anche se non sono un grande esperto del settore,infatti mi son dimenticato di dire di postarlo in virus e sicurezza.
In futuro quando dovrai installare un programma se è possibile scegli l'installazione personalizzata per evitare inutili add on.
