This is a nightmare: Win32:DNSChanger-VJ [Trj]

Viruses and worms

My apologies, but I have to step away from my computer for a few minutes. I’ll be back shortly.

I see that you have windows all in one repair, once you have merged the registry files could you run that and in the advanced section select :

Repair Winsock and DNS Cache

Under my Avatar is a globe
Press that and it will take you to my Skydrive
There you will find a Zip file with your name
Download that and extract the four registry files to the desktop
Right click each one and select Merge
Accept the warnings

Run the windows repair all in one fix

Now download a fresh Copy of Combofix and run that please

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

  • IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

[*]Double click on ComboFix.exe & follow the prompts.
[*]Accept the disclaimer and allow to update if it asks

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

The second registry file legacy_mpssvc won’t merge. I get an ‘Error accessing the registry’ message.

24

I finally was able to run Combofix. Avast isn’t popping up anymore, so I guess on first appearances this virus has been removed. In any event, here is the Combofix log.

25

Here’s the second part of the Combofix log.

26

Avast is no longer detecting anything, but it just seems my computer is running slow. Maybe I’m being paranoid, but it seems to me there are some remnants of this virus still affecting my system. Any advice on whether or not there’s some software I need to scan for remnants of this virus would be much appreciated!

27

Still two oddballs to kill - lets see how it runs after this

  1. Close any open browsers.
  2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
  3. Open notepad and copy/paste the text in the quotebox below into it:
File:: c:\windows\system32\drivers\fzwobwfr.sys c:\windows\system32\drivers\zdwpeujx.sys

Driver::
fzwobwfr
zdwpeujx

Save this as CFScript.txt, in the same location as ComboFix.exe

http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif

Refering to the picture above, drag CFScript into ComboFix.exeWhen finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

I’m kind of new to Avast, and honestly I have no clue how to completely disable the program. Is it as simple as ‘right clicking’ on the Avast icon in the tray and disabling the shields control?

29

Yes select disable all untill reboot

Do not let avast sandbox or quarantine anything whilst Combofix is doing its thing

30

OK here is the new Combofix log file.

31

How is the computer behaving now ?

32

After restarting the computer, everything seems to be completely normal. I can’t thank you enough; nicely done!

33

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL
[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands [resethosts] [emptytemp] [Reboot]

[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

[*]Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
[*]In the Run box, type in ComboFix /Uninstall (Notice the space between the “x” and “/”) then click OK

http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg

[]Follow the prompts on the screen
[]A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

[*]Click Start.
[*]Open My Computer.
[*]Select the Tools menu and click Folder Options.
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[]Click OK.

SPRING CLEAN

To manually create a new Restore Point

[*]Go to Control Panel and select System
[*]Select System
[*]On the left select System Protection and accept the warning if you get one
[*]Select System Protection Tab
[*]Select Create at the bottom
[*]Type in a name i.e. Clean
[*]Select Create

Now we can purge the infected ones

[*]GoStart > All programs > Accessories > system tools
[*]Right click Disc cleanup and select run as administrator
[*]Select Your main drive and accept the warning if you get one
[*]For a few moments the system will make some calculations
[*]Select the More Options tab
[*]In the System Restore and Shadow Backups select Clean up
[*]Select Delete on the pop up
[]Select OK
[]Select Delete

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

http://img233.imageshack.us/img233/7729/mbamicontw5.gif

Malwarebytes. Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

[*]Microsoft Windows Update

To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ?

Keep safe :wave:

Cleanup complete and everything is back to normal; thanks again for all the help, essexboy! :slight_smile:

My pleasure ;D

https://forms.fbi.gov/check-to-see-if-your-computer-is-using-rogue-DNS

Anyone can use ipconfig and check @ fbi.gov and manually enter the actual ip found in ipconfig using “Check Your DNS” and manually enter the ip address you have on that page. Should give peace of mind on this.
