Gentilissimi redattori di MegaLab,
innanzitutto ringrazio Voi e il Vostro sito per la disponibilità e per l' aiuto.

Ho letto attentamente la Vostra guida, ma non sono sicuro al 100% di cosa includere nello script di avenger, soprattutto in riferimento al passaggio "Nel report di Kaspersky non è detto che sia sempre visibile il rootkit che si nasconde nella cartella C:\WINDOWS\system32\drivers\ includetelo lo stesso nello script. ". Dunque come procedere per l' individuazione ed eliminazione di suddetto rootkit?

Vi riporto lo scan di Kasperky online come ho visto fare ad altri utenti:

Si, ho appena provato a reinstallare l' antivirus e non sono riuscito.

Devi riscaricare l'installer dell'antivirus perché il worm lo ha corrotto. Neanche così si reinstalla?

Qualcosa non è andata a buon fine con l' Avenger.
Per sicurezza sto ripetendo la scansione kaspersky online e i virus sono ancora lì.

Il ripristino di sistema l' avevo disattivato esattamente come indicato da http://www.MegaLab.it/articoli.php?id=510

Posto il nuovo scan effettuato con Kaspersky online

Non so se sia rilevante ai fini del problema, ad ogni avvio di windows il blocco note si apre con il file desktop.ini contenente

Riscarica gli installer dei programmi di sicurezza e prova a reinstallare un antivirus.

PS. Non sembra avessi il Bagle...

Sono appena riuscito ad reinstallare l' antivirus.

Ringrazio tutti per il cortese aiuto.

Mi sono rimasti un paio di dubbi.. Credevo che il problema fosse "Trojan-Downloader.Win32.Bagle.jd", quindi il Bagle, se non era lui, cos'era?

Non riesco a capire perché all' avvio si continua ad parire il blocco note con la stringa "[.ShellClassInfo]
LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21787"

Con quali programmi si suggerite di fare un' analisi approfondita del sistema?

Verifica che nella cartella di esecuzione automatica non vi sia un file desktop.ini.

Ripristina la modalità provvisoria utilizzando questo file.
