Virus

Come rimuovere virus e spyware? Le carte di credito sono davvero sicure in rete? È possibile navigare anonimi? Con quali programmi tutelare la propria privacy? Come proteggere i file importanti? Se volete una risposta a queste e altre domande questo è il luogo giusto!

HO installato un programma di grafica, credo falso, al riavvio del pc mi e' sparito il segno di spunta sul ripristino di configurazione e il collegamento ad internet e' lentissimo. Potreste indicarmi su come risolvere il problema e scovare il maledetto worm?
grazie.

si sono riuscito ad entrare alla provvisoria e sto facendo una scansione con avg ma non ha trovato nulla, il computer e' sempre piu' lento e anche io penso di aver contratto un brutto virus ma non riesco ad individuare quale.
Qualcuno ha qualche suggerimento?

ciao

inizia a scansionare con combofix


Disattiva l'antivirus e i programmi anti-spyware

Disconnetti il pc da internet

scarica combofix da qui:
http://download.bleepingcomputer.com/sUBs/ComboFix.exe

Se hai delle icone di collegamento a programmi sul desktop, crea una cartella apposita e copiale al suo interno

Doppio click su combofix.exe e segui le istruzioni passo a passo, ricordati di dare invio dopo i vari passaggi

Quando avrà finito creerà il log C:\combofix.txt salvalo e postalo come gli altri report.

NON TOCCARE MOUSE E TASTIERA durante la scansione.

ciao

per ora lascia stare le scansioni ed esegui questa procedura, hai mbr infetto


Scarica MBR:EXE direttamente nella Directory C:\ (è di fondamentale importanza che venga scaricato dove si trova il S.O,

http://www2.gmer.net/mbr/mbr.exe

Riavvia il Pc in modalità provvisoria
Da Start - Esegui - digita C:\mbr.exe e clicca su OK (fai copia-incolla)
La scansione dura pochi secondi.

-Lancia di nuovo mbrfix con l'opzione di pulizia (da Start-->Esegui--> digita C:\mbrfix.exe -f (attenzione allo spazio prima di -f)
Elimina l'altro per non confondere, oppure postali tutti e due per non sbagliare

ciao

dovresti rieseguire le procedure di prima, non ho capito se hai fatto gmer prima o dopo mbr

elimina tutti i file creati prima da MBR, li trovi in C:\

riesegui ora la procedura

Start\Esegui\ copia-incolla : C:\mbr.exe e clicca OK.

Posta il il log , che si trova dove hai scaricato l'MBR.EXE e cioè in C:\.
