istsvc.exe

[orpheus]

Oggi sono andato da una mia amica per un problema di spyware sul suo pc. In pratica dopo 10 minuti (o poco +) ke è in internet gli appare la finestra ke un processo Generic Host Win32 è andato in crash (con conseguente possibilità di inviare l'errore a microsoft) ..dopodichè pochi minuti dopo l'apparizione di questa finestra la connessione e tutto il pc s'impallano tanto da dover riavviare il tutto.

Ho fatto una scansione con adware e mi ha trovato questo malware istsvc con le relative kiavi di registro, ovviamente in esecuzione e quindi ineliminabile anke se termino fisicamente tale processo dal taskmanager mi dice ke il file nn puo' essere cancellato poichè in esecuzione.

Allora disattivo il ripristino di sistema, vado in modalità provvisoria e da lì riesco a cancellarlo (faccio due passate per sicurezza sia di adware ke di spybot e il problema sembra risolto)

Riavvio normalmente il pc e faccio una nuova scansione con adware
e tutto è regolare... appena accedo a internet xo' il file si ricrea e torna in esecuzione rendendo inutile tutto quello ke ho fatto.


Ki mi sa dare una mano?? qcuno ha avuto un problema simile??

grazie per eventuali risposte
