[Win XP] Non si apre Cambia Utente

[Mister Zippo]

Faccio una scansione completa e elimino tutto,ma mi accorgo che il pc è molto più lento all'avvio e quando faccio partire alcune applicazioni di Windows,nel Task Manager non appare il mio nome sotto Nome utente,infatti nel pannello di controllo se faccio doppio clic su Account Utente non succede nulla...che succede? Ho fatto il controllo con hijackthis e questo è il risultato:

[blue_tech]

ci sono queste tre voci che non ho mai visto:

O4 - HKUS\S-1-5-19\..\RunOnce: [nltide_3] rundll32 advpack.dll,LaunchINFSectionEx nLite.inf,C,,4,N (User '?')

O4 - HKUS\S-1-5-20\..\RunOnce: [nltide_3] rundll32 advpack.dll,LaunchINFSectionEx nLite.inf,C,,4,N (User '?')

O4 - HKUS\S-1-5-18\..\RunOnce: [nltide_3] rundll32 advpack.dll,LaunchINFSectionEx nLite.inf,C,,4,N (User '?')

e questa che viene vista come sospetta:

O23 - Service: fastnetsrv Service (fastnetsrv) - Unknown owner - C:\WINDOWS\system32\FastNetSrv.exe



magari prima di fixare, fai uno scan completo con mbam
e se al posto di avg metti avira è meglio
