Title: virus xmlka e processo svchost infiniti
Post by: REDACTED on January 29, 2015, 10:56:13 PM
Ciao a tutti !

Ho un problema come in oggetto;
avast rileva che c'è un virus, definito xmlka ( c:windows/explorer) ed ogni tot minuti compare il pop-up che mi avverte che è stato bloccato.
invece nei dettagli dei processi c'è attivo il processo svchost una decina di volte con utilizzo del disco o della memoria quasi sempre al 100%.

Ho windows 8.1, ho già provato a fare il ripristino ma è fallito, la scansione con avast non ha rilevato niente ed anche malwarebytes che ha  rilevato dei file danneggiati non è riuscito a risolvere. Non so più che fare...

Grazie

Ciao
Prova a scaricare  Farbar Recovery Tool Scan e salvarlo sul desktop.

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.

Ciao,
ho chiesto ad un malaware remover specialist se può aggiungersi a questo topic.
Tra qualche ora (spero), dopo che ha visionato i logs, ti dirà come procedere

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 (http://www.bleepingcomputer.com/download/delfix/)

(https://dl.dropboxusercontent.com/u/73555776/delfix.JPG)


: 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 (http://www.forbes.com/sites/eliseackerman/2013/01/11/us-department-of-homeland-security-calls-on-computer-users-to-disable-java/)

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 (http://www.geekstogo.com/2600/how-to-disable-java-in-your-web-browser/) and How to unplug Java from the browser (http://krebsonsecurity.com/how-to-unplug-java-from-the-browser/))

If you do need to keep Java then download JavaRa  (https://singularlabs.com/software/javara/javara-download/)
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
(https://dl.dropboxusercontent.com/u/73555776/javara.JPG)


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

CryptoPrevent (http://www.foolishit.com/vb6-projects/cryptoprevent/) install this programme to lock down and prevent crypto ransome ware

(https://dl.dropboxusercontent.com/u/73555776/CryptoPrevent.JPG)

Malwarebytes (http://www.malwarebytes.org/mbam-download.php).

Update and run weekly to keep your system clean

Unchecky (http://unchecky.com/)

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.

To learn more about how to protect yourself while on the internet read this little guide  Best security practices  (http://www.bleepingcomputer.com/forums/t/407147/answers-to-common-security-questions-best-practices/)Keep safe  :wave:
