Ciao a tutti, ho un grosso problema, in una rete aziendale, pc con xp sp3, ho questo problema su una decina di computer, l'officescan trova il virus conficker o kido in c:\windows\system32\x, ma se faccio girare parecchi remove tool del kido non trova nulla infetto.
Ho fatto la scansione anche con il rescue cd di antivir ma niente!
il fatto è che dopo poco dall'accensione alcuni servizi che sono avviati in auto si spengono(server, broswer, firewall, workstation, audio...).
Non so + cosa fare e inventare per non formattare i pc.
Ecco il log di system scan

Ciao lalecco,

In questo topic una carrellata di vari tools per la rimozione di Conficker/kido.

Vedi se ti può essere utile.

[lalecco]

Ciao, grazie ma tutti i tool non riportano infezioni.. non so più cosa fare

[bdoriano]

Quando utilizzi i tool, disconnetti i pc dalla rete?

[lalecco]

scusa, ma non riesco a capire cosa cambia facendo la scansione con il cavo staccato, ho fatto anche la scansione con antivir rescue cd che lavora non in ambiente esterno linux e non in rete ma...
grazie

[bdoriano]

Più che con Avira Live CD, dovresti provare la scansione con Kaspersky Rescue CD.

Se, invece, decidi di utilizzare i tools che ti ho proposto precedentemente, devi staccare i pc dalla rete, altrimenti risulteranno totalmente inefficaci.
