Problemi con Google. Si tratta di un malware?

[ata]

Aiutatemi a capire quello che sta succedendo nel mio pc. Tre giorni fa ho subito un attacco da diversi malware/trojan, o era uno solo?, causato da una mia distrazione (ho dato l'ok per l'accesso di un programma conosciuto, ora non ricordo quale, che me lo chiedeva). La maggior parte dei files .exe mi risultavano infetti e Windows defender li aveva bloccati tutti. In modalità provvisoria sono riuscita a fare un po' di pulizia (con Avgfree e TrojanRemover) , poi ho disattivato una voce che permette a Windows defender di bloccare tutto. Al riavvio apparentemente funzionava tutto normalmente. Mi sono collegata a Internet (uso la chiavetta di Alice) e ho notato che la pagina di Google non era più in italiano né presentava più il filtro "pagine in italiano". Ho provato allora a cercare Google Italia ed al suo posto sono comparsi altri siti (ad esempio: http://searchingandclick34.com/) o pagine bianche o questa:
Da notare che dalla pagina di Google non si possono modificare le impostazioni. Oltre a questo il collegamento è un po' lento.
Nel frattempo Avg mi segnalava la presenza di un file infetto che non riusciva ad eliminare ( cookies sqlite) e l'ho dovuto fare più volte manualmente.
Posto il log di HijackThis, chiedo il vostro aiuto per capirci qualcosa (Combofix non è compatibile con il mio Windows 7):

la foto non è che aiuti molto, però ti direi di scaricare malwarebytes, aggiornarlo e fargli fare una scansione.
Abbandona adware e windows defender e passa a qualche programma più serio come malwarebytes o superantispyware

Problema Google risolto!

ho fatto anche una scansione completa con il programma che mi è stato consigliato ed ho trovato:
