Solitamente quell'errore appare appare perchè il sistema cerca un programma che è stato eliminato ed è rimasto qualche rimasuglio. Potrebbe trattarsi anche di un malware.
Comunque ci sono delle voci da eliminare:

Chiudi tutti i programmi e disconnesso da internet,
Lancia HijackThis e clicca sul secondo pulsante Do a system scan only
inserisci il segno di spunta nel quadratino davanti alle righe sotto indicate, una volta seleziona clicca il tasto
Fix checked per procedere all'eliminazione, comparirà una finestra clicca su SI per accettare e l'operazione è conclusa.
Ti preciso che eliminando le voci 04, i programmi non vengono toccati ma viene solo disattivato l'Avvio automatico, inutile......basterebbe solo l'antivirus.
Ricorda che Hijackthis deve essere avviato da una cartella a lui dedicata. Solo così Hijackthis creerà copie di backup prima di apportare modifiche.

Alla fine Fai una pulizia con Ccleaner compreso il Registro, per il registro spunta tutte le voci, acconsenti al backup quando richiesto.

Scarica ed installa MalwareBytes: scarica la versione Gratuita non la Premium
clicca qui per il download: http://it.malwarebytes.org/
Alla fine dell'installazione nell’ultima schermata deseleziona la voce Attiva la prova gratuita di Malwarebytes Anti-Malware Pro.
Se il sw è in inglese, vai nella scheda Settings e seleziona la voce Italian dal menu a tendina Language per tradurre il programma in italiano.
Prima di fare la scansione AGGIORNALO. (è molto importante)
Poi clic su SCANSIONE seleziona la voce scansione di minaccia
Elimina gli eventuali file infetti trovati. (li devi selezionare, e poi cliccare su "Rimuovi selezionati")
Posta il log.

Scarica Adwcleaner sul desktop:
http://general-changelog-team.fr/fr/downloads/finish/20-outils-de-xplode/2-adwcleaner
Chiudi tutti i browser (è importante IE,Firefox Chrome ecc...)
Clicca sul pulsante "Scan".
Finita la scansione clicca su "Clean"
Conferma con OK le varie finestre che ti compariranno.
Il pc si riavvierà, e uscirà il log con le eliminazioni.
Postalo qui.

Fai sapere se tutto a posto. Ciao
