Qualcuno puo' interpretare questo log ed aiutarmi a debellare un trojan che mi rallenta in maniera drammatica tutto il sistema. Grazie

Ciao Tommygun e benvenuto nei forum di Zeus News

apparentemente il Log mostra solo dei residui di rimozioni del trojan Bombka che però non dovrebbero causarti rallentamenti... Hai già provato a deframmentare l'hard disk?

Comunque diamo una controllata

Scaricati Unhackme, installalo ed avvialo. Guarda se ti trova qualcosa

Disabilita il ripristino di configurazione: clicca con il tasto destro sull'icona del Desktop "risorse del computer", dal menù a tendina scegli "proprietà". Metti il flag alla voce "Disabilita ripristino configurazione di sistema" e premi "OK"

Riavvia in modalità provvisoria: premi F8 al Boot e dal menu che seleziona "modalità Provvisoria" (safe mode)

Avvia HijackThis dal link sul desktop e clicca "Do a System Scan only", metti un segno di spunta sulla casella accanto a queste voci e al temine premi "Fix chacked"

[TommyGun]

Mi sembra che vada molto meglio, cosa ne dici Holyfay :

Direi proprio di si, il log adesso è pulito

Elimina i file eventualmente presenti nella cartella c:\windows\temp, soprattutto se terminano con ????.tmp.exe

Poi, come ulteriore verifica, fai una scansione online con Panda. Segui queste istruzioni:

# premi il pulsante "Scan your PC"
# nella nuova finestra che si apre clicca il pulsante "Check Now"
# inserisci le informazioni richieste (paese, stato, email) e premi "Send"
# seleziona una opzione "Home User" o "Company"
# clicca su "Scan Now"
# Accetta l'installazione del controllo ActiveX
# inizierà il download del file, aspetta che abbia terminato
# al termine clicca su "My Computer"
# quando Panda avrà completato la scansione clicca il pulsante "See Report" e salvalo sul tuo pc.

Se il log di Panda ti sembra sospetto ci risentiamo: postalo qui
