adware.Win32.BHO.ba

[klimt]

premetto che proteggo pc con NOD32 e Sygate personal firewall pro.
la scansione con e-squared free mi ha rilevato:

-adware.VB!sd5 o VB.y
-adware.Win32.BHO.ba
-NSIS media

pur mettendo in quarantena,adware.Win32.BHO.ba è sempre presente e non riesco ad eliminare C:\windows\Sistem32\windexserv.dll in cui è presente neanche manualmente.

che fare?grazie.

Ciao, elimina quel file con killbox, e poi posta un log di hijackthis.

[klimt]

-fatto,ma mi appare finestra con "this file could not be deleted".clicco ok e mi scompaiono icone desktop.ho dovuto con task manager chiudere sessione per tornare normale.

-a quanto pare anche nsis media è ancora qui(mi si è aperta finestra vuota)

-allego logfile
