Svchost infetto
« on: March 02, 2015, 10:45:44 AM »
Buongiono,
è la prima volta che scrivo, e lo faccio in quanto mi appaiono minacce rivelate di Avast di un virus URL:Mal sul processo Svchost.exe da vari URL:
blackled.info, epictory.info, reduled.info. Questo succede sia all'accensione del computer (laptop ACER con windows 7 64 bit) e a volte durante la navigazione (uso Firefox).
Ho provato a fare scansione con Avast, Malwarebytes, JRT, Adwcleaner ma sembra tutto ok.
Mi aiutate per favore? Grazie!!!

Ciao,
prova a scaricare Farbar Recovery Tool Scan e salvalo sul desktop.
 http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/
Nota: È necessario eseguire la versione compatibile con il sistema. Se non siete sicuri di quale versione si applica al sistema scaricare entrambi e cercare di farli funzionare. Solo uno di loro verrà eseguito sul vostro sistema, che sarà la versione giusta.
 

     Tasto destro del mouse per eseguire come amministratore (gli utenti XP fare clic su Esegui dopo il ricevimento del Windows Security Warning - Apri file). Quando si apre lo strumento fare clic su Sì.
     Selezionare addition.txt in fondo
     Premere il pulsante Scan.

Quindi allega entrambi i log.

Ciao,
ho chiesto ad un malaware remover specialist di dare un' occhiata ai tuoi log, non so se riesce stamattina, magari nel pomeriggio ti risponde.

Potreste farmi sapere se questo si ferma gli avvisi

Could you let me know if this stops the alerts

CAUTION :  This fix is only valid for this specific machine, using it on another may break your computer

Open notepad and copy/paste the text in the quotebox below into it:
 
Quote
CreateRestorePoint:
BHO: No Name -> {9421DD08-935F-4701-A9CA-22DF90AC4EA6} ->  No File
Toolbar: HKLM - No Name - {9421DD08-935F-4701-A9CA-22DF90AC4EA6} -  No File
EmptyTemp:
CMD: bitsadmin /reset /allusers

 
Save this as fixlist.txt, in the same location as FRST.exe

Run FRST and press Fix
On completion a log will be generated please post that

Subject to no further problems   :)

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Remove tools

Download and run Delfix




: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article

I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)

If you do need to keep Java then download JavaRa
Run the programme and select  Remove Java Runtime.  Uninstall all versions of Java present
Once done then run it again and select Update Java runtime > Download and install Latest version



Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

CryptoPrevent install this programme to lock down and prevent crypto ransome ware



Malwarebytes.

Update and run weekly to keep your system clean

Unchecky

Click on the link above to be taken to Unchecky.com
click the very large Download button.
click Save
Click Open folder
Right click on the Unchecky_setup and choose to Run as Administrator
Once open click the Install button.
Then click on Finish
Unchecky is now installed and will help you keep unwanted check boxes unchecked, this is a fire and forget programme  ;)

It is critical to have both a firewall and anti virus to protect your system and to keep them updated.
