Ciao a tutti,
ho un piccolo problema (almeno spero) da qualche giorno quando accendo il pc all'avvio avg mi segnala la presenza di un'infezione più precisamente troijan horse small.AOQ e dice che il file si trova in "C:\WINDOWS\system32\Drivers\mchlnjDrv.sys." la cosa strana è che se gli dico di rimuoverlo o di spostarlo in quarantena avg mi dice che non può perchè non trova il file. In effetti seguendo la directory che mi da il file non c'è, ho letto in vari forum che potrebbe essere un falso positivo, per mè rimane un mistero.
P.S. il mio PC non ha (almeno all'apparenza) nessun problema.
Se può servire allego un log.
Sono nelle vostre mani, grazie in anticipo Juri.

ciao

hai ragione a dire che e' fantasma ...non vedo niente a parte questo PCAccelerate.exe

fai una scansione con kaspersky online e vedrai il fantasmino come esce fuori


http://www.kaspersky.com/virusscanner


1. Clicca su Kaspersky Online Scanner
2. Clicca su Accept
3. Partirà un Update
4. Vai nella colonna di sinistra dov'è scritto Scan e scegli my computer
5. Al termine della scansione in fondo a destra trovi la voce View Scan Report. Cliccaci sopra e poi clicca su Save "Save Report As" e salvalo sul desktop.
Per la scansione è richiesta l'installazione del java.

ciao shapiro, per la scansione di kaspersky viene richiesta l'activeX?

sembra un falso positivo di bug di AVG ..... disinstalla e opera con altro antivirus ....... ciaux e buon lavoro
