Ciao .
Non ti sembrano tantini 3 antivirus ? (anche se i file sono "missing"risultano attivi)
Disistalla McAfee e AVG8 e tieni Kaspersky.
Assicurati di avere accesso a file e cartelle nascosti
(Pannello di controllo-> Opzioni Cartella-> Visualizzazione)
1) Metti la spunta su: Visualizza file e cartelle nascoste
2) Togli la spunta: nascondi file protetti di sistema (consigliato)
Disattiva il ripristino configurazione di sistema, e tienilo disattivato, fino alla soluzione del problema http://guide.aiutamici.com/guide?C1=7&C2=68&ID=80121

Avvia in modalità provvisoria http://guide.aiutamici.com/guide?C1=7&C2=68&ID=80122

Avvia hijackthis, metti la spunta alle voci che andrò ad elencarti e con tutte le applicazioni chiuse e disconnesso da Internet,premi su fix checked

Trova e cancella i file in rosso:
C:\WINDOWS\system32\adsmsextz.exe
Riavvia il pc.
Dai una pulita (registro compreso)con CCleaner http://www.aiutaamici.com/software?ID=11223
*********************************************************************************************************
Scarica ed installa MalwareBytes:
clicca qui per il download : http://www.malwarebytes.org/
Prima di fare la scansione AGGIORNALO.
Esegui una scansione completa del sistema e, una volta terminata la scansione,posta il log che verrà rilasciato in questa discussione.
Assicurati che tutti i files evidenziati siano selezionati e clicca Rimuovi Selezionati
Posta un nuovo log di HJT.
Riferisci se i problemi sono risolti.

Ciao.
Prova a fixare quelle voci in Modalità normale.
Poi pulisci con CCleaner (registro compreso).

Importante: Disabilita il tuo antivirus e chiudi TUTTI i programmi aperti,e dopo aver scaricato COMBOFIX, chiudi la connessione.

Scarica Combofix
http://download.bleepingcomputer.com/sUBs/ComboFix.exe
Salvalo sul desktop.
Doppio click su combofix.exe (comparirà una videata.)
Digita 1 premi Invio e segui le indicazioni.
Al termine, verrà creato un file log chiamato C:\ComboFix.txt. Postalo qui.
Durante l'operazione di scansione è importante non usare il PC (neanche il mouse) e attendere pazientemente la fine delle operazioni.

Disinstalla combofix in questo modo: (dopo che avrò visto il log)
Start
Esegui
nella finestra di dialogo, digita (oppure, copia ed incolla) questo comando: Combofix /u e premi invio poi cancella le cartelle in "C" di combofix (qoobox)
