Ciao amicici ho bisogno del vostro aiuto per risolvere una questione che mi è capitata oggi, allora in pratica ho avuto la "brillante" idea di prestare la mia psp a mio cugino (lui mi ha prestato il ds,abbiamo fatto a scambio) per una settimana quasi, solo che quando me l'ha ritornata dentro c'era un simpatico "
ospite",infatti oggi pomeriggio collegando la memory stik al pc per metter su mp3 e roba varia da portare con me al mare,(non l'avessi mai fatto
) avast comincia a segnalare che la memory stik da 4 giga è infetta da due file: disk knight.exe e autorun.inf
,al che comincio una ricerca per capire di cosa si tratta ed ho trovato questa descrizione del virus Disk knight version 4.2 antivirus/virus!
Si professa come un antivirus invece e' un virus! che prende di mira le pen drive usb,e supporti di memoria esterna ed infetta i pc.
E' piuttosto innocuo : non ti permette di visualizzare i tuoi file sulla chiavetta usb.
Come eliminarlo?
DALLA CHIAVETTA USB:in esplora risorse andare in strumenti-opzioni cartella e attivare la visualizzazione dei file di sistema, adiamo sulla chiavetta e per magia apparira il file knigt.exe ---> Cancellalo!
DAL PC: premere ctrl alt canc e aprire il pannello dei processi in corso visualizzare il processo knight.exe ed arrestarlo
andare in c:windows e cercare il file knight.exe ELIMINALO
Niente di piu' semplice.
**********
seguendo questo schema passo passo, non ci sono riuscito, allora non mi sono arreso e in un blog straniero ho trovato questa guida:
http://www.mikeyleung.ca/2007/08/07/disk-knight/seguendo tutto alla lettera sembra che sono riuscito ad eliminare la minaccia o almeno avast(ultima versione) mi dice che il pc è pulito,stessa cosa antimalawarebytes, la memory stick della psp è tornata visibile (prima non me la faceva propio aprire)
ho fatto una scansione anche con: Microsoft Windows Malicious Software Removal Tool (aggiornato ad agosto 2010) ultimo aggiornamento disponibile per ora e mi dice che il sistema è pulito
sperem, poi però ho letto che questo virus si annida anche in c:windows col nome kinight.exe e nei file di registro di sistema
e se non si fa un controllo approfondito dei file di sistema e del registro di windows il virus protrebbe ripresentarsi
speriamo di no, comunque super amicici ora vi posto un log hijackthis datemi buone notizie vi prego!!!
