Hi,

I posted a plea for help with my dns changer problem 3 days ago but have received no reply.

I am new to this and am not sure if I am doing something wrong. does anybody even see this post?

I could really use some advice. I can't get rid of zlob dns changer. Spybot keeps finding it but even though it says it fixes it, if I do another scan, it finds it again. I tried scanning in safe mode and with system restore turned off but it didn't help.

Please help,

jonhut

Hi and Welcome to BleepingComputer,

Sorry for the delay, it seems your original post was just overlooked by all.

I would start out by doing a scan with Malwarebytes...

It can be downloaded from any of these places...

http://www.malwarebytes.org/mbam.php

alternate download link 1
http://malwarebytes.gt500.org/mbam-setup.exe

alternate download link 2
http://www.majorgeeks.com/Malwarebytes_Ant...ware_d5756.html

Double-click on mbam-setup.exe to install the application. (If it will not download, install, or open after installation, change the name of it to whatever you want and change the .exe extension to .bat or .com or .pif or scr and then double click on it to run.)

When the installation begins, follow the prompts and do not make any changes to default settings. When installation has finished, make sure you leave both of these checked:

Update Malwarebytes' Anti-Malware
Launch Malwarebytes' Anti-Malware

Then click Finish.

MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.

Make sure the "Perform Quick Scan" option is selected. Then click on the Scan button.
If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.

When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found". Click OK to close the message box and continue with the removal process.

After running that scan, post the log of the full results here and then download, install, update and run a quick scan with SuperAntiSpyware and post the log of the full results here. This scan may take some time to complete so please be patient.

That can be downloaded from SuperAntiSpyware.com

If it will not download, install, or open after installation, change the name of it to whatever you want and change the .exe extension to .bat or .com or .pif or scr and then double click on it to run.

If possible, both programs should be run in regular Windows, not safe mode. Allow both programs to remove whatever they find and if they tell you that you need to reboot your computer to complete the removal process, reboot into normal Windows.

p.s. Hey I just noticed in the log; Rootkit.DNSChanger.H; is that it?

Yes, that could very well be it, but go ahead with the SuperAntiSpyware scan.

I hate to see rootkits on a computer as having one of those is really bad. I am sorry but there is no way to know for sure, even after cleaning the computer of it and having it no longer show up in scans, that your computer is actually safe and trustworthy unless you do a format of the drive and reinstall Windows.

Because of this rootkit infection, you should not do any online banking or online transactions involving any kind of bank card. If you have done any of that stuff since becoming infected, you should contact your bank.

The below links contain some information you might be interested in.

Let us know which way you decide to go with this computer, cleaning or reformatting.

Chewy, thank you so much for coming into this thread. I was in over my head if this person wanted to go ahead with disinfecting as I have never used RootRepeal and do not really know what to do with the results.

I was going to advise this person to use RootRepeal and post the log and then wait for one of you more knowledgeable ones to come along for further advice if they wanted to go ahead with disinfecting.

Thank you for taking the waiting out of the equation. :thumbsup:


Jonhut, good luck to you. You are in good hands with Chewy :flowers:

Thanks Stang.

Hi Chewy,

Ok this sounds really bad. Pit in my stomach.

The site link for downloading root repeal gave me a message saying they were low on bandwidth and I would have to try again later. I have to work in the morning, so I will try it tomorrow evening and report back then.

I really appreciate you guys helping me out. I hope I can fix this.


Thanks

jonhut

Chewy,

I downloaded rootrepeal but can't get it to open. When I try to open it I get the little hourglass for a couple of seconds and nothing else happens. I am running xp home so I should be able to open zip files, shouldn't I?

I have to go to work, so I will check back when I get home.

Thanks
jonhut

On the clean computer and a jump drive

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.
