    You havent cleaned the virus entirely or the virus has made a change to your system files.

    Run online scans and use AVG.
    Ping the sites you cannot access.
    Try another browser (download it)

    The simple versions of these viruses add incorrect entries to the file
    C:\WINDOWS\system32\drivers\etc\hosts
    The only necessary entry is 127.0.0.1 localhost.

    Or they might hijack the DNS setting on your network card, changing it to a value of their choosing. Run ipconfig /all and check the DNS servers setting.

    -

    However the one I saw the other day was a lot nastier. TDSSserv.sys
    It appeared to place it's own driver to check some simple address checks on DNS and web requests.

    So googling/ yahooing/ MSLive would send you to some dodgy site that impersonated itself as go.google.com or go.yahoo.com.

    So trying to ping www.eset.ie, www.trendmicro.com and a pile of others would ping 127.0.0.1. This would occur even when the network card was disconnected and the ipconfig /flushdns had cleared the local DNS cache.
    The bug was still causing problems in safe mode with networking.

    Using nslookup to get the IP address and plugging that into the browser would succeed.

    By going into Control Panel\System\Hardware\device manager\Non-plug and Play Drivers, choosing View\Show Hidden Devices I found this TDSSserv.sys driver file.
    Click disable, not uninstall.

    Nod32 and AVG scans failed to notice or fix the problem. I didn't see anything suspicious in hijackthis (but I'm no expert.) Google searches for a fix were unusually unhelpful.

    I ended up nuking the laptop from orbit just in case.

    * Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

      Your using an old version of Adobe Acrobat Reader, this can leave your pc open to vulnerabilities, you can update it here :
      http://www.adobe.com/products/acrobat/readstep2.html




      Below I have included a number of recommendations for how to protect your computer against malware infections.

      * Keep Windows updated by regularly checking their website at :
      http://windowsupdate.microsoft.com/
      This will ensure your computer has always the latest security updates available installed on your computer.

      * To reduce re-infection for malware in the future, I strongly recommend installing these free programs:

      SpywareBlaster protects against bad ActiveX

      * SpywareGuard offers realtime protection from spyware installation attempts. Make sure you are only running one real-time anti-spyware protection program or there will be a conflict.

      Make Internet Explorer more secure
      • Click Start > Run
      • Type Inetcpl.cpl & click OK
      • Click on the Security tab
      • Click Reset all zones to default level
      • Make sure the Internet Zone is selected & Click Custom level
      • In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to "Prompt", and ("Initialize and Script ActiveX controls not marked as safe") to "Disable".
      • Next Click OK, then Apply button and then OK to exit the Internet Properties page.


      *ATF Cleaner - Cleans temporary files from IE and Windows, empties the recycle bin and more. Great tool to help speed up your computer and knock out those nasties that like to reside in the temp folders.

      *NoScript - Addon for Firefox that stops all scripts from running on websites. Stops malicious software from invading via flash, java, javascript, and many other entry points.

      *Keep a backup of your important files - Now, more than ever, it's especially important to protect your digital files and memories. This article is full of good information on alternatives for home backup solutions.

      * MVPS Hosts file replaces your current HOSTS file with one containing well known ad sites and other bad sites. Basically, this prevents your computer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer, meaning it will be difficult to infect yourself in the future.

      * Please consider using an alternate browser. Mozilla's Firefox browser is fantastic; it is much more
      secure than Internet Explorer, immune to almost all known browser hijackers, and also has the best built-in pop up
      blocker (as an added benefit!) that I have ever seen. If you are interested, Firefox may be downloaded from
      Here

      * Take a good look at the following suggestions for malware prevention by reading Tony Klein’s article 'How Did I Get Infected In The First Place'
      Here

      *ERUNT (Emergency Recovery Utility NT) allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed.

      * Recovery Console - Recent trends appear to indicate that future infections will include attacks to the boot sector of the computer. The installation of the Recovery Console in the computer will be our only defense against this threat. For more information and steps to install the Recovery Console see This Article. Should you need assistance in installing the Recovery Console, please do not hesitate to ask.

      Thank you for your patience, and performing all of the procedures requested.
