PC lento, pobabile infezione?

[valerioz]

Ciao a tutti,
è da qualche settimana che il mio portatile è decisamente lento (softwares, browser, ecc) nei pimi 40 - 50 min di utilizzo, e l'hard disk continua a girare insistentemente in questo periodo. Inoltre anche la CPU risulta occupata dal 7 al 15% se non oltre pur non utilizzando nessuna applicazione. Poi, superato questo periodo, il tutto sembra funzionare correttamente.
Vi allego il log eseguito con Hijack, per un vostro controllo.

Il laptop è un Asus Travelmate 7720G con Vista

Grazie,

Il Kaspersky è un buon antivirus, mi sembra strano che non ti abbia segnalato la presenza di qualche codice dannoso. Piuttosto ho notato che all'avvio hai troppi programmi coi relativi processi. Questo è uno dei motivi per i quali il pc rallenta. Ti consiglierei di eliminarli, lasciando il solo antivirus. Apri quello che ti serve quando ti serve effettivamente. Noterai le migliorie di sicuro.

ciao

hai un'infezione da togliere

scarica avenger sul desktop
http://swandog46.geekstogo.com/avenger.zip
Decomprimi l'archivio

Avvia il file avenger.exe

Copi e incolli nella finestra: "Imput script here" il SEGUENTE testo COSI' come l'ho scritto CON la dicitura files to delete:

files to delete:
C:\Program Files\RelevantKnowledge\rlvknlg.exe

folders to delete:
c:\programmi\relevantknowledge\

Togli il segno di spunta dalla voce Scan for Rootkits
Premi il pulsante Execute
Rispondi di Si alle due richieste di Avenger
Adesso il tuo computer dovrebbe riavviarsi, nel caso non succedesse, riavvialo tu manualmente
Al riavvio del computer, copia e incolla qui il contenuto del blocco note che apparirà.



Scarica e installa
http://www.malwarebytes.org/mbam/program/mbam-setup.exe
Aggiornalo e fai una scansione completa del computer. Posta il rapporto ottenuto. Per ora non rimuovere nessuna eventuale minaccia rilevata
