Ciao a tutti! Da qualche giorno, mentre navigo, mi si aprono di continuo finestre pop-up contrassegnate da uno strano simbolo colorato in alto a sinistra, sulla barra del browser. Poco fa mi sono accorta che una di queste è una falsa pagina di Ebay (i caratteri sono molti grandi e si vede chiaramente che è un falso). Inoltre, cliccando sulle varie opzioni sulla pagina mi si aprono finestre che portano la dicitura "favorit" in fondo (assurdo!!)
In questi ultimi giorni mi è capitato di prendere ben 2 virus, quindi ho pensato potrebbe trattarsi di quello. Se fosse realmente così che tipologia di virus potrebbe essere..? Che cosa devo fare?
Grazie e ciao ^^

Ciao gore, innanzitutto ti consiglio di scrivere in minuscolo altrimenti sembra che urli...;)

Hai provato con Trojan Remover? (http://www.simplysup.com/tremover/download.html)

Ti chiedo scusa, non l'ho fatto apposta :x: (anche se a dir la verità mi verrebbe da urlare per davvero!!!! :inkaz: )

Comunque no, lo scarico subito! Grazie per l'aiuto!!

Potrei sapere di che tipo di virus si tratta? :mm:

Il mio antivirus attuale è Avast! Combofix è un antivirus..?

Comunque allego il log di HiJack This:

Ho fatto una ricerca e ho scoperto di che tipo di virus si tratta. A quanto pare è un virus che attacca i DNS dei router, indirizzandoci a siti di phishing.
