Ciao, procedi così:

chiudi HijackThis in una cartella a lui dedicata (possibilmente non sul desktop), altrimenti perdi i backup;

<b>Disattiva il Ripristino configurazione di Sistema</b>: ------ > <b>procedura:</b>

<b>avvia in modalità provvisoria</b> ----- > <b>procedura:</b>

<b>rendi visibili le cartelle nascoste</b> ------ > <b>procedura</b>:
da Risorse del computer:
Strumenti >> Opzioni cartella >> visualizzazione;
metti la spunta su:
<i>Visualizza file e cartelle nascoste</i>;
togli la spunta da:
<i>Nascondi file protetti del sistema(consigliato)</i>


Avvia hijackthis, con tutte le applicazioni chiuse, premi su <b>Do a system scan only</b> , spunta ed elimina <b>(fix checked)</b> la seguente riga:

---

<font color=red>O4 - HKLM\..\Policies\Explorer\Run: [5T19I3B27A] C:\WINDOWS\csrs.exe
</font id=red>

---

elimina il file in rosso:
___________________________________________
C:\WINDOWS\<font color=red>csrs.exe</font id=red>
___________________________________________

Da Start >> Esegui, incolla la stringa <b>%temp%</b> ed elimina tutti file della cartella temp;

Vai su Strumenti >> Opzioni Internet, elimina la cronologia, i files temporanei internet, i cookies;

svuota il cestino;

riavvia il computer normalmente.

fai qui un controllo antivirus
http://www.bitdefender.com/it/

<b>Alla fine:</b>

rinascondi le cartelle di sistema;
riattiva il ripristino configurazione di sistema e, se tutto è a posto, creane uno nuovo.


Dovresti installare un firewall. Scarica da questo sito <b>Zone Alarm:</b> o <b>OutPost 1.0</b> e disattiva quello di Windows.

scusami ma sbagliavo.all'avviamento del computer, compare sempre la schermata di authority\sistem.ripeto la citazione della schermata:c:\windows\system32\services.exe è terminato in modo imprevisto con codice 000101013(ad esempio).inoltre ho fatto la scansione antivirus come mi avete proposto e non sono affetto da nessun tipo di virus.posto nuovamente il nuovo log di hijack this.attendo risposte grazie mille Logfile of Trend Micro HijackThis v2.0.2

attendo risposte grazie dell'aiuto

si l'ultima volta era comparsa.ora faccio nuovamente la scansione e la posto , grazie mille per l'aiuto

Adesso mi fai vedere i programmi che hai in avvio automatico:

Start >> Esegui >> regedit. Vai sulla chive <i>HKEY_LOCAL_MACHINE</i> e poi nell'ordine apri <i>Software >> Microsoft >> Windows >> CurrentVersion</i>. A questo punto fai <b>un</b> clic sulla cartellina <b>Run</b>. Dovresti pubblicare uno screenshot di quello che vedi a destra.

Se non l'ha cancellato devi cambiare le impostazioni come ti ho detto. Ma se quella finestra non se ne va devi fare quello che ti ho suggerito nel mio ultimo post.
Un'altra cosa: la finestra ti fa vedere un conto alla rovescia superato il quale il computer si spegne?
