zlob.dnschanger / trojan.dnschanger

Hi Pete and Welcome to Majorgeeks


Yes logs will indeed help but we do have a set of steps that we need following as this gets your PC/s to a known state and along the way generated a few logs that will need attaching to your next posts.

If their are multiple PCs involved with this malware infection then what I would do as the fix maybe slightly different for each and to keep things fro becoming confusing i would start a new thread for each PC involved with this malware infection and name the thread something like zlob.dnschanger / trojan.dnschanger infection PC #1 and then #2 etc


Please follow the instructions in the below link and attach the requested logs when you finish these instructions.

• READ & RUN ME FIRST. Malware Removal Guide

• If something does not run, write down the info to explain to us later but keep on going.

• Do not assume that because one step does not work that they all will not.

Notes:

1. If you run into problems trying to run theREAD & RUN ME or any of the scans in normal boot mode. You can running steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
   
   • Starting your computer in Safe mode
2. If you have problems downloading on the problem PC, download the tools on another PC and burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.

Since MBAM has removed your infection and you are saying that it comes back, it sounds like that rest of the process for removing this infection (also commonly called a WareOut infection) has not been finished. These instructions are included in the below procedure

WareOut Removal

The above proecedure and the infection you mentioned were mentioned in another sticky thread title:

Special Removal Procedures - SmitFraud,Virtumonde,Qoologic,SpyAxe,Look2ME,Zlob


I'm not sure if FixWareOut supports Vista, but you could disconnect your PC from the internet, run MBAM, and then follow the remaining instructions in the WareOut Removal procedure to get your network settings restored to the proper DNS server.

 

Yes the tool itself is obsolete since other scanners now pickup the infections and remove them. However obviously some manual steps like I had given in that procedure will still need to be run. I'll have to update that thread to remove FixWareOut and insert MBAM but keep the rest.

If you are not having any other malware problems, it is time to do our final steps:

1. We recommed you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
3. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
   • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
   • "%userprofile%\Desktop\combofix" /u
     • Notes: The space between the combofix" and the /u, it must be there.
     • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
   • Delete the C:\combofix folder from combofix (if it exists)
4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
7. Go to add/remove programs and uninstall HijackThis.
8. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
9. If you are running Vista, Windows XP or Windows ME, do the below:
   • Refer to the cleaning steps in the READ ME for your Window version and see the steps to Disable System Restore which will flush your Restore Points.
   • Then reboot and Enable System Restore to create a new clean Restore Point.
10. After doing the above, you should work thru the below link:
