Ciao a tutti.
Ho bisogno del vostro aiuto.
Durante la navigazione invece del sito richiesto vengo dirottato su una pagina google con elenco di siti porno o, peggio ancora, direttamente sulla homepage di siti porno.
Vi prego di essere il più dettagliati possibile nella descrizione dei passi da seguire perché le mie conoscenze di informatica sono piuttosto limitate.
Questo è il logfile creato da Hijack this.
Grazie.
