Ciao di nuovo, sono nuovo del forum, vi chiedo un grosso aiuto. Ho beccato questo virus rilevato da Avira --TR/Dropper gen
Dopo aver letto le varie discusioni inerenti al virus TR/Dropper gen ho fatto tutto quello che era possibile.
Il mio virus si trova in C:\ Documents and setting\Al User\Dati applicazioni\ Avira\AntiVir Desktop\ Temp\ e sono la cartella AVSCAN-20101202-16070-2191CA4B che è vuota e poi la cartella AVSCAN-20101202 -185855 -1979CB4D dove dentro vi è ARK6. tmp che poi si trasforma ARK13.tmp e non riesco ad eliminarla.
provato in tutti i modi anche con killbox.
Non posso formattare il PC. allego hijackthis.txt e poi il comboFix

vi ringrazio in anticipo

Ciao e benvenuto nel forum,
Disattiva il ripristino configurazione di sistema, e tienilo disattivato, fino alla soluzione del problema
Avvia hijackthis, metti la spunta alle voci sotto con tutte le applicazioni chiuse e disconnesso da Internet,premi su "fix checked":
O2 - BHO: Ask Toolbar - {D4027C7F-154A-4066-A1AD-4243D8127440} - C:\Programmi\Ask.com\GenericAskToolbar.dll
O3 - Toolbar: LEC - {1DBAB667-A486-421e-AFE4-CF07DD0088E5} - C:\Programmi\Power Translator 10\Applications\LEC IE Translation Extension.dll
O3 - Toolbar: Ask Toolbar - {D4027C7F-154A-4066-A1AD-4243D8127440} - C:\Programmi\Ask.com\GenericAskToolbar.dll


Poi scarica Malwarebytes QIO apri e lo aggiorni, poi fai una scansione completa, non veloce, elimina tutto quello che trova, posta il log.
Fai una pulizia con Ccleaner registro compreso.
Poi vai in C:/windows cerca la cartella Prefetch la apri ed elimina tutto il contenuto, non eliminare la cartella, se tutto è a posto, ripristina configurazione del sistema e crea un punto nuovo.
Fai sapere, ciao.
