Olimpo Informatico

Ciao a tutti!
Ieri sera il mio fedele Panda Internet Security 2007 mi ha avvisato dell'attacco di un virus.

Ho fatto quello che diceva Panda, cioè ho chiuso tutti i programmi aperti e ho riavviato il pc.

Dopo 2 scansioni antivirus (una ieri e una oggi) il computer risulta privo di codici maligni.

Nel log di Panda si legge:

==================================================================================

Virus rilevato: Bck/VB.TW Protezione Antivirus 02/18/07 18:54:50 Spostato Percorso: c:\windows\router.exe
Virus rilevato: Trj/Downloader.MXA Protezione Antivirus 02/18/07 18:54:37 Spostato Percorso: c:\windows\winmsgr.exe

==================================================================================

Mi rimangono però due stranezze da chiarire:

1) i due files infetti risultano "spostati". Ma dove sono finiti, dal momento che la Quarantena è vuota?

2) Ad ogni avvio del pc mi compare una finestrella di errore che riporto qua sotto:



- non c'è modo di toglierla?
- è un segno che c'è ancora qualche residuo di infezione?

Grazie anticipate se qualcuno vorrà aiutarmi!
Posto sotto il log di Hijackthis.

P.S.: forse per curiosità vorrete sapere cosa stavo facendo quando ho beccato il virus... avevo appena scaricato un codec per Windows Media Player al fine di visualizzare un filmato .asx che mi aveva inviato un amico via mail.

ciao
questi sono da eliminare
O4 - HKLM\..\Run: [Dispatcher] C:\WINDOWS\dispatcher.exe ( è un trojan)
O9 - Extra button: (no name) - {e2e2dd38-d088-4134-82b7-f2ba38496583} - %windir%\Network Diagnostic\xpnetdiag.exe (file missing)

per l'errore prova così:
start/esegui digita regedit
HKLM/Software/Microsoft/OLE/EnableRemoteConnect
Verifica che il valore EnableRemoteConnect sia impostato su " Y" per Sì.

Molto gentile

ciao
l'errore è legato all'applicazione Office, non c'entra nulla i virus. controlla le impostazioni.
http://support.microsoft.com/kb/244264/it

le voci sono da fixare con HiJack. la procedura è seguente
Ricordati di mettere HIJACK in una cartella a lui dedicata (in Programmi o Documenti), l'importante è che non si trovi sul desktop o in cartelle temporanee.... è importante se vuoi salvare i backup

Disabilita il Ripristino di configurazione su tutte le unità
(nota che questo ELIMINERà TUTTI i punti di ripristino, quindi se non riscontri più problemi, crea almeno un nuovo punto di ripristino dopo questa procedura)

Avvia il sistema in Modalità Provvisoria

CON TUTTE LE APPLICAZIONI CHIUSE....
.Avvia Hijack e clicca su "do a system scan only"

Metti la spunta a questi voci e clicca su "fix checked"

[ulrikke]

In effetti qualche problemino con Office ce l'avevo... ma solo dopo aver beccato il virus (o trojan, quello che è )

Comunque...

Dopo aver fixato quelle 3 voci con Hijackthis l'odiosa finestrella è scomparsa. Grazie!

Non riscontro altri problemi, quindi ho creato un punto di ripristino.

Posto un nuovo log di Hijackthis nella speranza che qualcuno mi ci dia un'occhiata... ora dovrebbe essere a posto.

Grazie mille!!!

Ora mi rimane la curiosità che avevo espresso anche nel mio primo post
