New possible Rootkit (Stuxnet Trojan horse) was signed by Realtek Semiconductor drivers

the Stuxnet trojan 'creates two pilots on the compromised machine, called mrxcls.sys and mrxnet.sys. The drivers are used to hide malware on the infected PC and the USB key. These two drivers are signed using the certificate of Realtek [Semiconductor, one of the largest Taiwanese hardware producers]...

A check of the validity of the certificate VeriSign, issuer of the certificate, shows that it is indeed legitimate...

they have rootkit features and hide files lnk and ~WTRxxxx.tmp in the root of the storage device'.»

    Each time Firefox opened

    == I tried to access a website

    Hello Dave deaf.

    It is possible that you have a problem with some Add on Firefox which is an obstacle to the normal behavior of your Firefox. Have you tried to disable all add-ons (just to see) to see if Firefox goes back to normal?

    Whenever you have a problem with Firefox, whatever it is, you must make sure that it is not caused by one (or more) of your installed modules, whether an extension, a theme or a plugin. To do this easily and cleanly, start Firefox in safe mode (remember to select disable all add-ons when you start safe mode). If the problem goes away, you know that it's an add-on. Disable them all in normal mode and allow them one by one until you find the source of the problem. See this article for more information on troubleshooting extensions and theme and this one for plugins.

    If you need help with one of your modules, you will need to contact the author.

    In addition, it is possible that your system is infected by malicious software. To search for malicious software, install, update and run these programs in this order. They are all free for personal use, some have limited functionality in their 'free mode', but the features you won't miss are not really necessary to find and remove the problem you have. Remember that not all programs detect the malware even!

  • Satellite M30X: Trojan horse - total Formate with recovery disc?

    Hello

    I had a Trojan horse on my Satellite M30X. My Antivirus deleted, but every time I've been connected to the Internet, it appeared again. Not connected to the Internet it doesn't give me any problems. As I couldn't get rid of him, I backed up all my data and do a fresh install from the recovery disc. As long as the button for LAN wireless is disabled, everything works fine, but just a little while, after I turned on it, I get a blue screen. When I restart my computer with WIFI turned on, it produces a blue screen before Windows is properly loaded, even during installation. I tried restoring 3 times, but it's always the same result.

    1 is it possible, that the Trojan horse destroyed things of the pre installation?
    2. I can't choose to make a formatting during the recovery process. All data are lost, but I feel that's not formate the hard drive correctly, when everything is destroyed. It crushes just stuff?
    3. is there a way to make a good formatting, then install completely new Windows?

    It is not a problem of my WLAN card, internet being no problem under Linux.

    Thank you for your help

    Hello!

    If you use the whole HARD disk Toshiba Recovery disk will be formatted so if you have any virus or Trojans on your laptop, they will be also deleted.

    But what BSOD code are you have? Are you sure that's the reason why the virus?
    You have the same problem if you connect a network cable to the laptop?

    Good bye

  • unidentified possible Trojan horse

    I think that my computer is infected with some sort of Trojan. I bought this MacBook Air in October and it worked perfectly until today. I tried to read a Web site and page could not finish loading and it kept opening other tabs very suspicious. When I visited perfectly firefox regularly guarded site redirecting them to pages like this:

    And there's always a pop up window asking me to download MacKeeper (I didn't download it!). The same thing happens when I use Safari.

    I checked the Add-ons, and I don't know what could cause me (even if I don't know what these modules are Flash and Java). I read that Java can cause Trojans and I installed it recently. But it was earlier this week and I did not notice something different.

    Then I not unhooked firefox and installed again, but nothing has changed. I googled and found that trojans and malware can be in the library, and then I found this:

    What should I remove without damaging my brand new computer? One of them may be the Trojan horse that I'm looking for? Besides that I also found a local.cfg in Macintosh HD, is that suspicious?

    I've updated to El Capitan earlier this week, and that's all right. A day earlier, I installed Adobe Illustrator and it required me to install Java, I don't like at all about Java. But as I said before this computer started showing this odd behavior today. Yesterday, I tried to download a pdf file from a Web site with a lot of pop ups, that could be the cause. But what can I do? I searched a lot of common trojans and found nothing.

    I have a friend suggested that I should download Malwarebytes and run tests. But is it safe?

    It's a scam jump upward. Do not call or click on anything either that it asks you. If you use Safari, force quit Safari then all by pressing and holding SHIFT restart Safari.

    MalwareBytes is safe.

  • I am not able to connect on all sites with my system XP displays a 404 error code after a Trojan horse (trojan. ADH.2) was found and quarantined by norton.

    Hello, I'm not able to get online at all sites with my system XP displays a 404 error code after a Trojan horse (trojan. ADH.2) was found and quarantined by norton. The system is slow or bottleneck at all, but I think that the registry has taken hostage by this Trojan horse. I tried to run Add ons, reset IE8, reinstall IE8 offline, I tried different users, tried to run a different browser (firefox). I can ping all the sites in the cmd prompt, but have no luck connection in the browser. A ran mohamed, superspyware, spybot. Is that what I can do without having to re install? I don't have the OS XP Media.

    original title: error 404 on all sites

    I wouldn't worry IPSec.

    I think the most important things to address are:
    1 search for rootkits.
    2 empty the DNS.
    3 reset the proxy settings.
    4 reset the TCP/IP and Winsock settings.
    Good luck!

    Theres a informative guide here - malicious software removal http://www.selectrealsecurity.com/malware-removal-guide

    You guide through the steps, then request that you download some tools to run on your PC. This information should hopefully clear your PC of malicious software (if one is found).

    The tools, to which it refers are programs like malwarebytes, tdss killerand others, all links included in the document.

    Remember, back up your data (at a minimum, the essential must have all bookmarks in your browser and email music, documents, photos etc account information) before you start - just to be sure.


    If all goes well that should clean your PC from viruses or malware. Read the first guide to ensure that you have everything you need at hand and understand what needs to be done before you start.



    Once the PC looks clean, try to restart the service of security. If it still does not start, have a read of this post - http://answers.microsoft.com/en-us/windows/forum/windows_7-security/windows-security-center-service-has-been-removed/47b55525-f0be-4434-95c3-265fbba64807

    I searched a bit using Google and it seems to be the false positive. Only Superantispyware is showing this Trojan horse, but all other virus scanners do not show any alarm.

    Also this .exe file is already included in the image of recovery if she s no virus or Trojan horse.
