E' forse un virus???

[jacopino91]

ciao a tutti,
da qualche giorno mi è apparso in task manager un nuovo processo denominato System che, da quello k dice taski, dovrebbe essere un file SYSTEM.
Questo file però rallenta tutti i processi inquanto, al lancio di una qualsiasi applicazione, si "appropria" di grosse porzioni di CPU.
Inoltre se termino il processo, cliccando sull icona del "cassetto nforce" nella barra degli strumenti, mi appare il seguente messaggio: "Impossibile inizializzare il driver audio NVIDIA! installare e riprovare".
Al riavvio del pc, però, questo messaggio scompare...di cosa si tratta?? E' un virus??

Dubito sia colpa di un virus.

Scarica HijackThis
Salvalo in una cartella (non aprirlo direttamente, sennò non farà i backup!)
Apri l'eseguibile
Clicca quindi su "Do a System Scan and Save a Logfile"
Attendi che finisca la scansione
Quindi copia il contenuto del blocco note qui sul forum.

ecco il risultato della scansione con HijackThis

Non vedo nulla di anomalo.

Quale sarebbe il processo sospetto?

[jacopino91]

ti posto l immagine tratta dal taskmanager con l applicazione sospetta:[/img][/code]
in questo momento (x fortuna) nn sta attingendo a nex risorsa d sistema xò spesso, soprattutto nel caricamento di programmi, salvataggio di immagini etc. m da un sacco d problemi

[ste_95]

Qual è, la prima o la seconda?

[jacopino91]

la prima

[ste_95]

E' tutto regolare, non c'è nulla di cui preoccuparsi.
