Gentili utenti buongiorno. Il mio personal Lenovo R60e con S.O. xp professional 512 Mb Ram apparentemente va bene la cosa strana è che ieri Avira mi segnalava un virus e nel percorso C:\Doc and Settings si sono creati 2 Executable Jar File sospetti. Ho fatto una scansione on line con Panda che mi rilevava 4 file infetti, ma poi si è interrotta dopo 2 ore di scansione nonostante abbia l' adsl. Scansione con Malwarebytes negativa. Mah.

Vi allego il log di Hijackthis e vi ringrazio.

Scarica Combofix

http://download.bleepingcomputer.com/sUBs/ComboFix.exe

Salvalo sul desktop.

Importante: dopo aver scaricato COMBOFIX chiudi la connessione disabilita il tuo antivirus e
chiudi TUTTI i programmi aperti,(Firewall compreso) e

Doppio click su combofix.exe (comparirà una videata.)

E' probabile che ti siano inviati messaggi dall'antivirus,(o dallo stesso Combofix)
tu ignorali.

Se ti verrà chiesto se vuoi Installare LA CONSOLE DI RIPRISTINO DI EMERGENZA, clicca NO.

Durante l'operazione di scansione è importante non usare il PC (neanche il mouse)
e attendere pazientemente la fine delle operazioni.
Al termine, verrà creato un file log sul Desktop, chiamato C:\ComboFix.txt. Postalo qui.

ps:se usi windows firewall,in xp è una cioffeca,sara' bene che ne installi un altro
