Scarica HijackThis, decomprimilo in una cartella tutta sua non temporanea (ad esempio mettilo in C:\HijackThis).
Avvialo e premi Do a system scan and save a log file, ti si aprirà una finestra di notepad con il risultato della scansione, copia e incolla qua il suo contenuto.

A quanto sembra tu hai il Trojan Vundo
Quindi:

Prova a scaricare il removal tool del Vundo.

Mettilo sul desktop e avvialo.
Quando ti si apre premi su Scan for Vundo.
Quando ha finito la scansione premi su Remove Vundo.
Ti chiederà se vuoi rimuovere i files, tu rispondi YES
Quando cliccherai yes il desktop diventerà bianco perchè il VundoFix inizierà a rimuovere i files.
Quando avrà finito ti chiederà se può riavviare il pc, premi OK.
