Ciao, hai utilizzato una versione meno recente di hijackthis.
Scarica qui
http://www.pc-facile.com/HijackThis_s267/
la 1.99.1.
Intanto, Riavvia in modalità provvisoria
(Avviare il computer.Subito dopo il calcolo della RAM e prima che inizi a caricarsi Windows, iniziare a premere ripetutamente il tasto F8 sulla tastiera. Continuare a farlo fino a visualizzare il menu Opzioni avanzate di Windows. Usando i tasti freccia sulla tastiera, scorrere le opzioni e selezionare il menu Modalità Provvisoria, quindi premere Invio)
Rendi visibili file e cartelle nascosti:
da gestione del computer>strumenti>Opzioni Cartella
Seleziona Visualizza
Spunta "mostra file e cartelle nascoste"
Togli la spunta da "nascondi file di sistema protetti"
Click OK
Apri hijackthis, premi “ do a system scan only”, cerchi e spunti le voci seguenti:
O3 - Toolbar: (no name) - {BA52B914-B692-46c4-B683-905236F6F655} - (no file)
O4 - HKLM\..\Run: [msci] C:\DOCUME~1\nicola\IMPOST~1\Temp\20065220590_mcinfo.exe /insfin
O4 - HKLM\..\Run: [.nvsvc] C:\WINDOWS\system\smss.exe /w
O16 - DPF: {4ED9DDF0-7479-4BBE-9335-5A1EDB1D8A21}
O16 - DPF: {BCC0FF27-31D9-4614-A68E-C18E1ADA4389} –
Premi fix checked
Cerchi ed elimini il file:
C:\WINDOWS\system\smss.exe /w
Elimina poi tutti i file temporanei di windows temp e tmp (da start>cerca>tutti i file e cartelle, copi e incolli: *.temp;*.tmp, ed elimini tutti quelli trovati)
sulle opzioni Internet cancella la cache di IE ( sull’opzione elimina file temporanei spunta anche “elimina il contenuto non in linea”, i cookies, cronologia)
svuota il cestino.
Da pannello di controllo.installazioni/applicazioni controlla che non vi siano programmi non installati da te
Riavvia in modalità normale e posta un nuovo log di hijackthis, fatto con la versione 1.99.1
