pc parte solo in modalita' provvisoria

[sheva]

il mio computer (un po' datato purtroppo) mi si avvia solo in modalita' provvisoria. In realta' si avvia normalmente ma appena tento di di far partire qualche cosa tipo internet a qualche prog. di scansione computer, si spegne. Anche in modalita' provvisoria se faccio "lavorare" il computer si spegne. Mi permette di andare su internet e poco piu'.Ho fatto girare spybot, ad-ware e avast. ma non hanno trovato niente di importante.Solo una volta mi e' uscito un messaggio con scritto C\windows\system32\.exe con un numero 1073741819. dopo di che' iniziava un conto alla rovescia e dopo 60 secondi lo spegnimento del pc. Cosa sara' successo un becccato un virus ?

grazie a tutti x l'aiuto


Ho un pentium 4 con xp professional service pack 3 512 di ram e 200 giga di hd

La ram va sicuramente incrementata, ma penso che i tuoi problemi nascano da infezioni. Visto che la modalità provvisoria parte, installa e scansiona con Hijackthis e poi posta il contenuto del file log prodotto. Se non conosci Hijackthis fai riferimento a questo topic viewtopic.php?f=7&t=87995 o cerca in questa sezione.

Ciao,Scarica Combofix da qui, mettilo sul sul desktop del computer infetto:
http://www.bleepingcomputer.com/combofi ... e-combofix
all'interno della pagina troverai una guida sul corretto utilizzo del programma, leggila attentamente.
Non installare la Console di Ripristino.

Portati, finita la scansione, in C:\ apri il file di testo ComboFix.txt copia ed incolla il suo contenuto in un prossimo post.

NB
durante la rimozione non dev'essere attiva la connessione internet e l'antivirus dev'essere disattivato.

Poi, da start > esegui, nel box bianco copia e incolla questo comando, virgolette comprese:
"%userprofile%\desktop\abc.exe" /killall
Premi OK, si dovrebbe avviare la scansione
