problema Trend ChipAwayVirus

[janluc]

ciao ragazzi, ecco a voi esperti il mio problema...
quando avvio il pc sento un avviso acustico tipo sirena e poi mi compare questa scritta in giallo su fondo nero prima che si avvii Windows XP:
"Trend ChipAwayVirus has detected a boot virus on your hard disk!
Press <ENTER> for more information or <c> to continue.
Complete virus protection for the Enterprise - http://www.antivirus.com"
se clicco su Enter mi manda al sito suddetto..per cui clicco su C e cosi mi dice:
"To prevent the data lost from your computer, Trend ChipAwayVirus will restart your system.
Insert a bootable clean floppy disk into your floppy driver.
Press <y> to restart your system or <B> to go to the previous screen."
appena clicco su Y..il pc parte normalmente....
che è successo?
come devo agire?

ciao
copia il testo del log che hai postato, e vai a questa pagina :
http://www.hijackthis.de/

incolla il testo del log, nel riquadro con sfondo bianco e premi analizza; poi, in hijackthis fixa tutte le voci in cui compare la X rossa e i ? giallo!!!!
miraccomando, solo quelli!!!!!!

[janluc]

scusate ma è da tanto che non accedevo..allora il problema non l'ho mai risolto ora riposto un nuovo log di hijackthis, perchè ho cercato di pulire il pc...ma niente da fare...mi sapete aiutare^??

[janluc]

c'è nessunooooooo????

[Luke57]

Ciao, scarica ComboFix sul desktop
http://download.bleepingcomputer.com/sUBs/ComboFix.exe

Disconettiti da internet

Avvia il file ComboFix.exe
Digita 1 per avviare il tool (non fare altre manovre durante la scansione, se le icone del desktop spariscono è normale)
Segui le istruzioni e alla fine verrà generato un log.
collegati e posta il report (C:\combofix.txt)

[janluc]

ok luke ho eseguito combofix ed eccoti il log...fammi sapere...grazie

[Luke57]

Ciao, copia questo codice:

Codice: Seleziona tutto

File::
E:\nideiect.com

Registry::
[-HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\mountpoints2\{3391ce9f-3181-11dd-a231-000c6e20cca3}]
[-HKLM\System\CurrentControlSet\Services\agony]

incollalo in un file di testo (blocco note di windows), salva obbligatoriamente il file con il nome CFScript.txt nella stessa posizione di combofix, trascinalo con il puntatore del mouse sull'icona di combofix per una nuova scansione ed eventuale riavvio.
Allega il nuovo report di combofix.

[janluc]

ciao luke, ma perchè devo copiare quel testo con "E:", se invece il mio sistema operativo è in "C:"?
grazie e scusa l'ignoranza...

[Luke57]

Ciao, figurati, è un malware che si inietta con la pendrive.

[janluc]

luke quindi se lo tolgo con combofix appena rimetto la pendrive lo riprendo?come devo comportarmi per evitare che la penna usb mi ricontagi il pc?
aiutami per favore

[Luke57]

Ciao, esegui quello che ti hoi suggerito, poi utilizza anche questo programma:
http://www.programmipc.it/sicurezza/ikill-10b.html

[janluc]

luke, perdonami, credo di aver fatto tutto cosa faccio per controllare definitivamente se ho risolto?
e poi mi spieghi a che serve e come si usa il programma kill?aspetto una risposta..grazie mille come sempre
