Ciao ragazzi!
Da qualche giorno, all'avvio del pc, compare una finestra RunDLL che dice così: C:\Users\Utente\AppData\Roaming\tztwtqwk.dll Accesso negato. Poi clicco su OK e scompare... però mi riappare sempre ai successivi avvii del sistema. Ho il S.O. W.Vista...
Vorrei sapere cos'è questa finestra... un virus?Come posso eliminarla?
Grazie!!

sempre in modalità provvisoria fai una scansione Antivirus,
se non hai un antivirus, utilizza questo programma in versione USB
http://www.aiutamici.com/software?ID=11485

quindi riavvia il computer e controlla se il problema e risolto, se e tutto OK riattiva il ripristino configurazione disattivato all'inizio di questa procedura e crea un nuovo punto di ripristino, in caso di problemi lascialo disattivato fino alla soluzione dei problemi

Fai una scansione antivirus on line da questo indirizzo
http://security.symantec.com/sscv6/default.asp?productid=globalsites&langid=it&venid=sym
se la scansione on line rileva dei virus significa che il tuo antivirus è stato infettato o non è in grado di risolvere il problema, ti consiglio di formattare il disco fisso e reinstallare tutto, altrimenti prosegui

Nel sistema non é presente un Antivirus, installa questo programma se non ne utilizzi già uno
http://software.aiutamici.com/software?ID=11537

Nel sistema non é presente un Firewall, installa questo programma se non ne utilizzi già uno
http://www.aiutamici.com/software?ID=80142

Ti consiglio di utilizzare questo programma per fare la copia di riserva del sistema, cosi se vieni infettato puoi ripristinare il sistema cosi come si trova, leggi la descrizione su aiutamici
http://software.aiutamici.com/software?ID=10988
