Buongiorno.
Il log non presenta grosse anomalie.
Problemi?

Questa:
O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file)
E' una voce che riguarda Windows Live Messenger.
Non è pericolosa, e non serve eliminarla, in quanto si rigenerebbe quando si usa tale programma.

Queste:
O4 - HKUS\S-1-5-20\..\RunOnce: [_nltide_2] regsvr32 /s /n /i:U shell32 (User 'SERVIZIO DI RETE')
O4 - HKUS\S-1-5-18\..\RunOnce: [_nltide_2] regsvr32 /s /n /i:U shell32 (User 'SYSTEM')

Queste voci [[_nltide_2]] sono dovute al fatto che hai istallato una copia di Xp con un cd modificato con [_nltide_2].
Per cui, anche queste sono regolari.
