Salve a tutti. Da alcuni giorni mi è comparsa questa finestra e non riesco a toglierla in nessun modo: Exception Processing Message c00000a3 Parameters 75b1bf7c 4 75b1bf7c 75b1bf7c e mi fa scegliere con i tre tasti Annulla Riprova e Continua.
Indipendente dalla mia scelta la finestra si richiude per riapparire dopo un 30ina di secondi.
Ho provato a scansionare il pc con Avast! antivirus poi con Malwarebytes e a ripulirlo pure con CCleaner, ma non ho mai trovato niente di infetto.

Ho letto su alcuni post passati che è necessario scaricare HiJackThis e postare il logfile. Così ho fatto e lo inserisco di seguito.

Per favore potete dirmi come procedere per toglierlo? Grazie mille
