Specs: Microsoft Windows XP Professional, 2.394 GHz / 3061 MB
Yo yo yo,
Seemed to have aquired the DNSChanger Trojan virus. I'm on a work network and a bit worried.
Goolgle redirects in both Firefox and IE8.
Have tried everything I can think of, installing and running Malwarebytes, HijackThis and many others in SafeMode, with no joy. Now when I run the AntiVirus, nothing is detected, but I still have the issue, any ideas?

Many thanks in advance to anyone who can help.

1) Can you please post your AVZ log:
Note: Run AVZ in windows normal mode. If avz.exe doesn't start, then try to rename the file avz.exe to something else and try to run it again. Make sure you have your web browser open in background before following the steps below.

1) To create the logfile, download AVZ by clicking HERE. Please save this file to your desktop or "My Documents" folder.

2) Next, unpack the file to a new folder using the Compressed (zipped) folders wizard built into Windows XP/Vista, or a zip utility of your choice.

3) Once you have unpacked the contents of the zip archive, please launch the file AVZ.exe by double clicking on it or right clicking and selecting Open.
Note: If you are running Windows vista launch AVZ.exe by right clicking and selecting Run as Administrator.

You should now see the main window of the AVZ utility. Please navigate to File->Custom Scripts. Copy the script below by using the keyboard shortcut CTRL+C or the corresponding option via right click.


Paste the script into the execution window by using CTRL+V keyboard shortcut, or the "paste" option via the right click menu. Click on Run to run the script, the PC will reboot. After the reboot the LOG subfolder is created in the folder with AVZ, with a file called virusinfo_syscure.zip inside. Upload that file to rapidshare.com and paste the link here.

2) Can you also upload your HijackThis log to rapidshare.com. Hijackthis: http://download.bleepingcomputer.co...

Follow these Steps in order numbered. Don't proceed to next step unless you have sucessfully completed previous step:

1) Run this script in AVZ like before, your computer will reboot:

SearchRootkit(true, true);

2) After Reboot. Attach a Combofix log, please review and follow these instructions carefully.

Download it here -> http://download.bleepingcomputer.co...

Before Saving it to Desktop, please rename it to something like 123.exe to stop malware from disabling it.

Now, please make sure no other programs are running, close all other windows and pause Antivirus/Sypware programs (http://www.bleepingcomputer.com/forums/topic114351.html Programs to disable) until after the scanning and removal process has taken place.

Please double click on the file you downloaded. Follow the onscreen prompts to start the scan. Once the scanning process has started please DO NOT click on the Combofix window or attempt to use your computer as this can cause the scanning process to stall. It may take a while to complete scanning and this is normal.

You will be disconnected from the internet and your desktop icons/toolbars will disappear during scanning, do not worry, this is normal and it will be restored after scanning has completed.

Combofix will create a logfile and display it after your computer has rebooted. Usually located in c:\combofix.txt, please upload that file to rapidshare.com and paste the link here.
