Hi,

I was recently infected with a virus on my computer (win32/heur). I used AVG and HijackThis to safely (from what I can tell anyhow) clean out most instances of the virus. However, it seems to have also added information to my tcp/ip settings to use a DNS server. I have tried numerous things, but still can not change the 2 IP's that are hard coded there. Can someone pls help? Below are the HijackThis logs (I have bolded what I see to be problematic). Here are the steps I took to try and correct the issue without any luck:

1) Selected all occurences of O17 below and "fix checked"
2) Went to the tcp/ip settings of my Local Area Connection and check off "Obtain DNS server automatically".
3) Re-started my computer
4) Once rebooted, ran "ipconfig /flushdns"
5) Re-started computer again
6) Did another scan with HijackThis, but had exact re-occurrences of O17 below…

Any help is appreciated! Thanks in advance.

Hello niroowns and welcome to the forums here at WTT!

:welcome:

There is a new variant of this Wareout infection that is changing the settings in routers, if present. Do you have a router? If so proceed with the following instructions. If not let me know.

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 a new HijackThis log, and also let me know how things are running now.

Glad it worked out. You should post the logs and we may want to run another scan or 2 to make sure you are all clean. Absence of symptoms does not always mean a clean PC. Up to you…
