Hello JP_Auto

Restart the computer and check it out - if firefox is still redirecting I want you to do the following

I want you to reset firefox back to defaults, this will remove everything from Firefox

I will let you keep your bookmarks so to do that you can go here - Export BookMarks

Now to reset firefox do the following.

  • At the top of the Firefox window, click the "Firefox" button,
  • go over to the "Help" sub-menu
    • (on Windows XP, click the Help menu at the top of the Firefox window) and select "Troubleshooting Information".

[*]Click the "Reset Firefox" button in the upper-right corner of the Troubleshooting Information page.

[*]click "Reset Firefox" in the confirmation window that opens.

[*]Firefox will close and be reset. When it's done. Click "Finish" and Firefox will open.

restart the computer and check firefox for me now

Well my good man, you did it. Simple restart didnt resolve the redirects but resetting firefox, then restarting PC,did. I tried about 10 sites and didnt get any redirects. Thank You so much.

I did have a few questions before you wrapped this up with your software removal instructions...

1. Am i able to clear that Trojan Win32/Tracur.AU that is in my MSE history?

2. MSE is telling me i havent run a scan in awhile (kinda strange considering thats all i've done this past week). Am i ok to now do so?

3. I must give you a donation for all you have done to resolve this for me. Would you say i am safe to now use sensitive info sites such as paypal? (i am always concerned with backdoor viruses that may have not been completely removed/repaired).

4. Lastly, Is there anyway you are able to tell where this virus came from? Reason i ask is because no one screws around on this computer (atleast they shouldnt be). It is strictly for graphic designs and running a vinyl plotter. Only thing i can think if it came from a font download but if im using a free font site, i only download zip files and scan it before i extract it. I was just wondering if you had any thoughts.

Thank you so much, Gringo

Hello

1, I use MSE at home (at work now) I know it can be done by offhand don't know how - but give me a PM tomorrow and I will check it out - also I know if you wait like 30 days it should clear on its own - I remember a trick for Norton about setting the clock 30 days forward and restarting to clear it - might work here try up to 90 days

2. yes you can but there still may be some quarintine folders around so don't get to alarmed if it finds something just let me know

3. yes I think it is OK at this time

4. I can't tell where but remeber one thing - nothing is ever free so freeware comes allot of things and what I see more often is the freeware comes with something not so bad but that will bring a friend later

you are more than welcome

Thank you for your replies and info.

In regards to question #1 (removing the trojan in history). It is located under the History Tab and listed as quarantined. All that i need to do is go down to the "detected item box" and check the box beside the virus name, then click remove. I apologize, i should have been more clear, i was only asking if it was OK for me to remove it. Thanks.

I will await your instructions for your software removal.

Hello JP_Auto

The Online scan looks very good!! It is only reporting backups created during the course of this fix!!


  • C:\Qoobox\Quarantine\<-- combofix

Very well done!! This is my general post for when your logs show no more signs of malware - Please let me know if you still are having problems with your computer and what these problems are.

:Why we need to remove some of our tools:

  • Some of the tools we have used to clean your computer were made by fellow malware fighters and are very powerful and if used incorrectly or at the wrong time can make the computer an expensive paper weight.
    They are updated all the time and some of them more than once a day so by the time you are ready to use them again they will already be outdated.
    The following procedures will implement some cleanup procedures to remove these tools. It will also reset your System Restore by flushing out previous restore points and create a new restore point. It will also remove all the backups our tools may have made.

:DeFogger:

Note** Defogger only needs to be run if it was run when we first started. If you have not already run it then skip this.

  • To re-enable your Emulation drivers, double click DeFogger to run the tool.
    • The application window will appear
    • Click the Re-enable button to re-enable your CD Emulation drivers
    • Click Yes to continue
    • A 'Finished!' message will appear
    • Click OK
    • DeFogger will now ask to reboot the machine - click OK.

Your Emulation drivers are now re-enabled.

:Uninstall ComboFix:

  • turn off all active protection software
  • push the "windows key" + "R" (between the "Ctrl" button and "Alt" Button)
  • please copy and past the following into the box ComboFix /Uninstall and click OK.
  • Note the space between the X and the /Uninstall, it needs to be there.
  • CF-Uninstall.png

:Remove the rest of our tools:

Please download OTCleanIt and save it to desktop. This tool will remove all the tools we used to clean your pc.

  • Double-click OTCleanIt.exe.
  • Click the CleanUp! button.
  • Select Yes when the "Begin cleanup Process?" prompt appears.
  • If you are prompted to Reboot during the cleanup, select Yes.
  • The tool will delete itself once it finishes, if not delete it by yourself.
  • If asked to restart the computer, please do so

Note: If you receive a warning from your firewall or other security programs regarding OTCleanIt attempting to contact the internet, please allow it to do so.

About Java

  • During the cleaning process if I found that Java was installed I asked for it to be uninstalled, Many home users will not miss it. If you use OpenOffice, play online games or use business applications which require Java, Then you need to install the latest version and make sure to disable it in your web browsers.
    If an application or website requires it, you should receive a notification indicating that when you attempt to launch that application or access that website.
    Link to download latest version. -
install Java
How to disable java in your web browsers - Disable Java

:The programs you can keep:

Some of the programs that we have used would be a good idea to keep and used often in helping to keep the computer clean. I use these programs on my computer.

Revo Uninstaller Free - this is the uninstaller that I had you download and works allot better than add/remove in windows and has saved me more than once from corrupted installs and uninstalls
CCleaner - This is a good program to clean out temp files, I would use this once a week or before any malware scan to remove unwanted temp files - It has a built in registry cleaner but I would leave that alone and not use any registry cleaner
Malwarebytes' Anti-Malware The Gold standard today in antimalware scanners

:Security programs:

One of the questions I am asked all the time is "What programs do you use" I have at this time 4 computers in my home and I have this setup on all 4 of them.

  • Microsoft Security Essentials - provides real-time protection for your home PC that guards against viruses, spyware, and other malicious software.
  • WinPatrol As a robust security monitor, WinPatrol will alert you to hijackings, malware attacks and critical changes made to your computer without your permission. WinPatrol takes snapshot of your critical system resources and alerts you to any changes that may occur without your knowledge.
  • Malwarebytes' Anti-Malware Malwarebytes' Anti-Malware is a new and powerful anti-malware tool. It is
    totally free but for real-time protection you will have to pay a small one-time fee. We used this to help clean your computer and recomend keeping it and using often. (I have upgraded to the paid version of MBAM and I am glad I did)
    Note** If you decide to install MSE you will need to uninstall your present Antivirus

:Security awareness:

It is good security practice to change your passwords to all your online accounts on a fairly regular basis, this is especially true after an infection. Refer to this Microsoft article

Strong passwords: How to create and use them Then consider a password keeper, to keep all your passwords safe. KeePass is a small utility that allows you to manage all your passwords.

The other question I am asked all the time is "How can I prevent this from happening again." and the short answer to that is to be aware of what is out there and how to start spotting dangers.

Here are some articles that are must reads and should be read by everybody in your household that uses the internet

internetsafety
Internet Safety for Kids

Here is some more reading for you from some of my colleges

PC Safety and Security - What Do I Need? from my friends at Tech Support Forum
COMPUTER SECURITY - a short guide to staying safer online from my friends at Malware Removal

quoted from Tech Support Forum

Conclusion

There is no such thing as ‘perfect security’. This applies to many things, not just computer systems. Using the above guide you should be able to take all the reasonable steps you can to prevent infection. However, the most important part of all this is you, the user. Surf sensibly and think before you download a file or click on a link. Take a few moments to assess the possible risks and you should be able to enjoy all the internet has to offer.

I'd be grateful if you could reply to this post so that I know you have read it and, if you've no other questions, the thread can then be closed.

I Will Keep This Open For About Three Days, If Anything Comes Up - Just Come Back And Let Me Know, after that time you will have to send me a PM

My help is free, however, if you wish to make a small donation to show your appreciation or to help me continue the fight against Malware, then click here -->btn_donate_SM.gif<-- Don't worry every little bit helps.
