io ti dico la mia il tuo post è aperto e visibile a tutti sotto lascio delle voci che sono sospette.







strano che non ti trova nulla : Malwarebytes Anti-Malware

@: 1) il tuo s.o xp è originale ?

2) hai un antivirus fra i più quotati "avira" magari usalo in modalità provvisoria ...
con il log postato non si vedono virus , ma "voci sospette"

3) hai detto che Malwarebytes Anti-Malware non rileva nulla al punto sopra cè qualcosa che non torna

Fatto tutto. Ecco il nuovo log.

Scusate l'intromissione.

Non è necessario disattivare il ripristino configurazione e andare in provvisoria.
Avvia hijackthis, metti la spunta alle voci e con tutte le applicazioni chiuse e disconnesso da Internet, premi su "fix checked"

Ciao.
Il problema è serio.
Vedi se sei capace, di eseguire queste indicazioni:

Start\Esegui\digita regedit e poi clicca ok.

Clicca sul + di HKEY_LOCAL_MACHINE.
Clicca sul + di SOFTWARE
Clicca sul + di Microsoft
Clicca sul + di Windows NT
Clicca sul + di CurrentVersion

Scorri finchè trovi la cartellina Winlogon.

Clicca una volta, sopra la cartellina Winlogon.
Nella pagina a destra, (quasi a fondo pagina) troverai:
Userinit.
Fai Doppio click su Userinit.
Si apre una finestrella, con scritto: C:\WINDOWS\system32\userinit.exe, (compresa la virgola finale)
Puoi confermare? (specialmente se trovi la virgola finale)

Se clicchi 2 volte ...dove?

In "dati valore, " non c'è scritto :
C:\WINDOWS\system32\userinit.exe,
