Trojan Horse

[giuliag]

L'AVG mi ha rivelato i seguenti problemi, probabilmente ricevuti tramite MSN:

cmosvc.exe Trojan horse Downloader.Small.AYJ C:\WINDOWS\system32\cmosvc.exe

image37.zip Trojan horse Downloader.Small.AYJ C:\Documents and Settings\Nico\Impostazioni locali\Temp\image37.zip

image35.zip Trojan horse Downloader.Small.AYJ C:\Documents and Settings\Nico\Impostezioni locali\Temp\image35.zip

image28.zip Trojan horse BackDoor.Ircbot.CDO C:\Documents and Settings\Nico\Impostazioni locali\Temp\image28.zip

cosa posso fare?

grazie

Ciao giuliag,

Prova per prima cosa a passare questo tool:

MSNFix.zip

• decomprimi il file, aprila cartella e clicca su MSNFix.bat. (attendi che ci vuole un attimo)
  
• Clicca E e premi Invio
  
  
• Poi clicca R e premi Invio
  
• Se l'infezione (o parte di essa) [Malware found] viene individuata premi N.
  
• Apparirà un rapporto... postarlo
  

prova ad usare quest'altro che è per la stessa infezione (il primo comunque sarebbe meglio)

NO worm Live Messanger

eseguirlo, selezionare in che driver avete installato Windows (solitamente è C:\)

e cliccare su "Cura il tuo pc dal worm di Live Messenger".

* Scarica ATF Cleaner

Avvia ATF Cleaner.exe con un doppio click

- clicca sul menu main

- seleziona la casella Select All

- clicca sul pulsante Empty selected

- aspetta l'avviso Done Cleaning.

(se non vuoi eliminare le password togli la spunta)

(se usi opera o firefox,spunta anche le loro sezioni)

posta anche un log di Hijackthis

Ho fatto come hai detto tu:

il testo di MSNFix è

MSNFix 1.588
