I just ran JRT and now when I try to launch Firefox I get the following error:[/size]

______________________________________________________________[/size]

Configuration Error[/size]

_______________________________________________________________[/size]

I see in JRT.txt (full contents of which are pasted below) the following line:[/size]

Successfully deleted: [File] C:\Program Files\mozilla firefox\Mozilla.cfg[/size]

Does this suggest that this configuration file was found to be infected?[/size]

Background Info:[/size]

I was attempting to use JRT Version: 6.9.1 (06.08.2015:1) downloaded from bleepingcomputer.com today to stop Conduit files from reappearing continuously. They repeatedly reappear even after Malewarebytes finds them each day and I repeatedly quarantine them. Malewarebytes had successfully stopped Conduit browser hijacking in IE and Firefox previously. It failed to stop it in Chrome but I no longer use Chrome so I just uninstalled it. [/size]

While running JRT[/size]

Having never used JRT previously I mistakenly thought it could take hours to scan files during which time it could run in the background while I continued my work. I attempted to launch Firefox while JRT was running and it did not launch. Not sure if that caused the problem, so I have pasted JRT.txt below for review. After JRT scan was finished I tried to launch Firefox again and that was when I first got the Configuration Error message above. I rebooted but I still get the configuration error message. Here is contents or JRT.txt..[/size]

I thought about restoring deleted file Mozilla.cfg file but did not for reason mentioned above. I also considered uninstalling and reinstalling Firefox or restoring registry from backup that JRT created. On second though however, I figure I might be better off seeking expert support here before digging myself in any deeper.[/size]

Hello there,

A member of the Malware Response Team told me that the file is malicious as it contains an injection script. There is a good chance your machine is infected.

Hi MarkSc,

I'm sorry  for the inconvenience this has caused you. I will do some more research but my understanding was that those type of .cfg files do not belong in that directory.

Let me know show you what a clean install of Mozilla Firefox looks like in the C:\Program Files\mozilla firefox folder: (c:\program files(x86)\Mozilla Firefox for me since I am running a 64-bit operating system).

As you can see, there is no such "Mozilla.cfg" file here hence why JRT considers any type of .cfg file in this particular directory/folder as malicious. I've had reports from other users and malware helpers saying that malware can hide there. We've seen for example a file called "my.cfg" being placed in this directory which then loads malicious javascript into FireFox creating popups for the user. However, this doesn't seem to be the case for you since there was not a mutual malicious javascript (.js) file detected.

Once again, I am sorry for the inconvenience. Were you having any trouble with while browsing in FireFox (pop ups, intrusive ads, etc)?

Lastly, I noticed the JRT log you linked appears to be incomplete. JRT detected FireFox hence the

~~~ FireFox

entry in the log

However, JRT will only include the above line if something related to FireFox was deleted. And while the "Mozilla.cfg" file is related to FireFox, it was deleted by a different and more generic portion of the tool; nonexclusive to FireFox.

Can you try repasting the log you received? I have a strong feeling that we are missing what is after the ~~~ FireFox line.

Nevertheless, thank you for the report. I will look further into the issue. In the meantime, I do think you're safe to reinstall FireFox if you'd like to.

Regards

I am running Win7 Pro SP1 on 32-bit platform and Firefox.exe is in directory

C:\Program Files\Mozilla Firefox\

There is nothing in JRT.txt besides what I pasted below. As I mentioned in my first email below, "I attempted to launch Firefox while JRT was running and it did not launch". I realize now it was not a good idea to attempt to lauunch firefox at that time. Might that explein why " ~~~ FireFox " appears as the last line in the JRT.txt log?.

I am by no means an expert so let me just tell you my hunch. It is that  JRT rightfully removed "mozilla.cfrg"  which based on some quick research appears to be at least a low-level threat. However, it appears firefox.exe is targeting "mozilla.cfrg" which is now missing so firefox.exe aborts.Do you agree and whether you agree or disagree what can you suggest I do next? Uninstall and reinstall Firefox maybe?

Thank you!

Yep, completely normal.

I realize now it was not a good idea to attempt to lauunch firefox at that time. Might that explein why " ~~~ FireFox " appears as the last line in the JRT.txt log?.

I kind of doubt it as JRT will close FireFox right before it starts to scan it. More than likely it's a bug with JRT that I haven't found yet.

However, it appears firefox.exe is targeting "mozilla.cfrg"

That's something interesting/new to me. Just so I understand correctly, the Mozilla FireFox shortcut on your desktop, and/or in the start menu points to the mozilla.cfg file instead of firefox.exe?

Uninstall and reinstall Firefox maybe?

I think this is your best route. I would recommend this. If your bookmarks are important to you and you'd like to save them, read: https://support.mozilla.org/en-US/kb/restore-bookmarks-from-backup-or-move-them

Desktop Shortcut and Quick Launch icon both point to "firefox.exe" and just ot be sure I attempted to launch "firefox.exe" from Windows Explorer filelist and got same error message. That is what leaves me thinking that "firefox.exe" is pointing to "mozilla.cfg".

This are specifics of what I propose to do. Please advise if you think this sounds ok:

1.) Uninstall Firefox with REVO Uninstaller since i have had better success with it in the past with programs that were corrupted.

2.) Next I am thinking I should run JRT again just to establish a baseline and see if there is more to be done past that "~~~ FireFox" entry.

4.) Rerun JRT to make sure it fully executes and returns a clean log.

Thanks again!

That sounds good. I actually prefer to uninstall using Revo as well

I uninstalled Firefox and ran JRT a secont time. As you can see below the log came back perfectly clean. Also, pleased to say in the past 2 days since the first run of JRT that MalewareBytes has not reported a single reoccurances of Conduit files. As reporteed below, prior to first running JRT it was finding them daily. Today I reinstalled Firefox and it is running fine.

My hunch is that an unwanted program caused modifications to firefox,exe including making it point to mozilla.cfg. JRT rightfully detected mozilla.cfg as a threat and deleted it thereby causing my corrupted incidence of Firefox to fail to launch.I probably should wait a day or two to see if Firefox web browsing allows Conduit file reinfestation but for now all looks good.

Thanks again!
