hello,

this is driving me insane. i noticed the other day that if i clicked on links from google, i was redirected to unrelated sites. i tried download all soerts of spyware tools, but either they were blocked or their updates were. i have since downloaded and installed some programs via usb stick. malwarebytes found the alureon trojan, and found dnshijacker reg entries and said it has removed both of them, however no matter what i do something keeps rewriting my dns servers in the registry. i cant get to windowsupdate and other sites. spyware programs fix this, but then on reboot or renewing my dhcp lease, the evil dns servers are back there. they are: 85.255.116.30 and 85.255.112.19. i have tried all sorts of things in combination of safe mode and normal: combofix, fixwareout, malwarebytes, superantispyware, avast, norman malware cleaner, and avg. nothing works, and no programs find anything wrong except the dns reg entries which they remove but then they just show up again. i used process explorer and reg explorer from sysinternals to isolate which process is resetting the dns registry settings at reboot and dhcp lease renewal, here is what i found:

svchost.exe:972 SetValue HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DhcpNameServer SUCCESS "85.255.116.30 85.255.112.19"
svchost.exe:972 SetValue HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{40B82B3D-7B98-41F0-9A68-06E538BB61EC}\DhcpNameServer SUCCESS "85.255.116.30 85.255.112.19"


i have attached attach.txt from dds.scr, and included dds.txt per the forum instructions, thanks in advance for your time and help!

Hello! :)
My name is Sam and I will be helping you.

In order to see what's going on with your computer I will ask for you to post various logs from the tools that we will use to resolve your issue. Please also share with me any information about how your computer is reacting and behaving each step of the way as we work through this process.


It sounds like a case of Zlob/DNSchanger that change the router's DNS settings. Please download Malwarebytes' Anti-Malware from Here or Here

Next disconnect your system from the internet, and your router, then…

Double Click mbam-setup.exe to install the application.
  • Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once the program has loaded, select "Perform Quick Scan", then click Scan.
  • The scan may take some time to finish,so please be patient.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Make sure that everything is checked, and click Remove Selected.
  • When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
  • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
  • Copy&Paste the entire report in your next reply.
Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediatly.


===============================================


Next you must reset the router to its default configuration. This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router. Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds). If you don’t know the router's default password, you can look it up HERE

However, if there are other Zlob-infected machines using the same router, they will need to be cleared with the above steps before resetting the router. Otherwise, the malware will simply go back and change the router's DNS settings. You also need to reconfigure any security settings you had in place prior to the reset. Check out this site here for video tutorials on how to properly configure your router's encryption and security settings. You may also need to consult with your Internet service provider to find out which DNS servers your network should be using.

Once you have ran Malwarebytes' Anti-Malware on the infected system, and reset the router to its default configuration you can reconnect to the internet, and router. Then return to this site to post your logs.

===============================================

Please post the Malwarebytes log and let me know how things are running now :thumbup2:

well crap, there goes about 15 hours of my life! no wonder i couldnt find any spyware, once i cleaned it out it was gone, and my computer was getting the evil dns settings legitly from my router. i had no idea spyware could change your routers settings. i switched em back to what they should be and feel confident my system is clean. thanks for helping to run such a great site!

Sneaky little buggers aren't they? :)


Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:
  • Disable and Enable System Restore. - If you are using Windows ME or XP then you should disable and reenable system restore to make sure there are no infected files found in a restore point left over from what we have just cleaned.

    You can find instructions on how to enable and reenable system restore here:

    Windows XP System Restore Guide

    Renable system restore with instructions from tutorial above

  • Make your Internet Explorer more secure - This can be done by following these simple instructions:
    • From within Internet Explorer click on the Tools menu and then click on Options.
    • Click once on the Security tab
    • Click once on the Internet icon so it becomes highlighted.
    • Click once on the Custom Level button.
      • Change the Download signed ActiveX controls to Prompt
      • Change the Download unsigned ActiveX controls to Disable
      • Change the Initialize and script ActiveX controls not marked as safe to Disable
      • Change the Installation of desktop items to Prompt
      • Change the Launching programs and files in an IFRAME to Prompt
      • Change the Navigate sub-frames across different domains to Prompt
      • When all these settings have been made, click on the OK button.
      • If it prompts you as to whether or not you want to save the settings, press the Yes button.
    • Next press the Apply button and then the OK to exit the Internet Properties page.
  • Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

    See this link for a listing of some online & their stand-alone antivirus programs:

    Virus, Spyware, and Malware Protection and Removal Resources

  • Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

  • Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

    For a tutorial on Firewalls and a listing of some available ones see the link below:

    Understanding and Using Firewalls

  • Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.

  • Install Spybot - Search and Destroy - Install and download Spybot - Search and Destroy with its TeaTimer option. This will provide realtime spyware & hijacker protection on your computer alongside your virus protection. You should also scan your computer with program on a regular basis just as you would an antivirus software.

    A tutorial on installing & using this product can be found here:

    Using Spybot - Search & Destroy to remove Spyware , Malware, and Hijackers

  • Install Ad-Aware - Install and download Ad-Aware. ou should also scan your computer with program on a regular basis just as you would an antivirus software in conjunction with Spybot.

    A tutorial on installing & using this product can be found here:

    Using Ad-aware to remove Spyware, Malware, & Hijackers from Your Computer

  • Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

    A tutorial on installing & using this product can be found here:

    Using SpywareBlaster to protect your computer from Spyware and Malware

  • Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
Follow this list and your potential for being infected again will reduce dramatically.
