    Hi there,

    Looks like I'm joining the Google Redirect party. Google searches redirect to sites like bookingbuddy and various other unrequested websites, some of which upset Firefox's Web of Trust extension. We were running Avira 9. I installed Avira Antivir 10 yesterday after uninstalling Avira during R&R Me First (so that MGTools would run).

    Before coming to MG we ran MBAM and picked up several viruses. SAS mostly found tracking cookies. I've attached those logs.

    Since the Google redirect persisted, I came to MG and ran Read & Run Me First. Just one virus was picked up by MBAM that I could see. We're on a 64bit Vista system here so I didn't run RootRepeal or ComboFix.

    I thought maybe our system was clean after R&R Me, but I ran another full MBAM scan to be sure and it picked up one more virus. I also ran several Linux boot CD scanners (Bit Defender Rescue, Avira Rescue, AOSS--maybe this was overkill?). Most came up clean, but AOSS came up with "Trojan Zefarch" in Users\Family\AppData\Local\... (a long string)\Chrome\contents\overlay.xvl.

    After all that, I went back into Firefox and Google was still being redirected. Any tips? After looking at some other threads I tried to run TDSSkiller, but it balked at our 64bit OS and refused to run.

    I've attached the MG R&R logs (labeled as such) along with a zip containing the more recent full MBAM scan and the previous MBAM and SAS scans.

    Many thanks for any help you can provide.

    Quite a few infections have been known to infect router hardware. If you have a router hooked up then you need to follow the instructions for your hardware and reset it to factory default settings. Normally there is a recessed push button type switch that needs to be held down for some number of seconds to do this. After resetting to factory defaults on your router, you will need to reconfigure the router for your network if you have made any changes to the default network setup.


    Now Click Start > Run and type in cmd
    • Click OK.
    • This will open a command prompt.
    • Type or copy and paste the following line in the command window:
      ipconfig /flushdns
    • Hit Enter
    • Exit the command window


    Now copy the bold text below to notepad. Save it as fixme.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.
    Make sure that you tell me if you receive a success message about adding the above
    to the registry. If you do not get a success message, it definitely did not work.



    Are you still having Google redirects? If so, do that happen with both IE and FireFox? Also do they happen in safe boot mode?

    Sadly, it doesn't seem to be fixed yet, but I really do appreciate the help in getting to the bottom of this.

    I reset my router and then flushed the DNS ("Successfully flushed the DNS Resolver Cache"--but only after "requiring elevation," weirdly, even though I was already running as administrator).

    I ran fixme.reg as instructed, and got a success message.

    Unfortunately, I still get periodic Google redirects, both in normal mode and in safe mode. Oddly, I don't think I've experienced it as an Administrator--only when I'm logged in to our Standard User account (which is how we usually surf).

    Google redirect doesn't happen with Opera or IE, as far as I can tell--although I don't use them as regularly as Firefox, I did try clicking on several search results that sometimes trigger redirects in Firefox and they all loaded fine.

    Thanks again for your help--any further assistance would be terrific.

    Then you are giving me logs for the wrong account! To possibly fix the problem account, scans need to be run on it. Cleaning the Admin account will not fix the Family account. You need to temporarily change the Family account to have administrator priviledges. Then reboot and log into the Family user account.


    Then run the below and attach new logs:
    • SUPERAntiSpyware - update before running scan
    • Malwarebytes - update before running scan
    • download new MGtools and run a new scan. Remember UAC must still be disable and you must right click and chose Run As Administrator even if a user account has admin priviledges.

    Ah, sorry about that. My new scans from the regular account are attached.

    Also, I don't know if it's relevant, but the computer had trouble booting this morning and startup repair had me do a system restore. I couldn't tell exactly which restore point it used, but it seems to have gone to one from after I ran all the R&R Me steps (ie the recycle bin stayed empty, etc).

    I also just installed Noscript in Firefox and it seems that a script from "Gissom.net" causes the redirects--blocking that seems to prevent redirects. I can't find anything about that script/website online, and when I checked on a clean computer there was no such script running on Google.

    So Noscript seems to solve the symptom, although I'm still concerned about what else might have caused the script in the first place.

    Likely an addon that was installed to FireFox. Sometime the best way to get rid of these is by uninstalling FireFox completely and deleting folders. If you don't delete the folders, the infection will remain. To do this, we recommend the below.



    We are going to be uninstalling your old version of FireFox and installing the new version. So do the below to save bookmarks:
    • Run FireFox and click Bookmarks.
    • Then select Organize Bootmarks.
    • Then on the next window click File and then select Export. Save the bookmarks.html file to your Desktop for later use in importing.
    Now download and save the installer for the current version of FireFox but DO NOT install it yet. Get it here: Mozilla FireFox

    You will need exit FireFox now and use Internet Explorer to continue with the below until we reinstall FireFox.

    • Start by uninstalling FireFox and then reboot. Do not skip the reboot.
    • After reboot, delete the below folders:
      • C:\Program Files (x86)\Mozilla Firefox
      • C:\Users\Family\AppData\Roaming\Mozilla\Firefox
    • Now reinstall FireFox from the file previously downloaded.
    • Import your bookmarks file. (similar process to exporting).
    Now see how things look without having installed any addons including NoScript.

    No luck, unfortunately. Google still redirecting (but as before it's only sometimes--maybe one click in ten, and the redirect vanishes if you hit Back and click on the link again).

    The you need to run more explicit detailed/repetitive tests with IE and see if it happens with IE so we can better determine where the problem might be. This is still sounding like a possible DNS issue. Earlier I ask you to reset your router to factory defaults. When you said you reset the router, did you mean you reset it back to factory defaults or did you just mean that you rebooted it or power cycled it?

    I restored factory defaults using the recessed button on the back of my Netgear router. I actually did it through their web-based control panel, too.

    Couldn't replicate the problem in IE, even with Protection turned off (in case it was doing the same thing as Noscript). I tried a couple of dozen times to click on results in searches that led to redirects in Firefox.

    I did notice, however, that two extensions had installed themselves to Firefox: XULRunner 1.9.1 and Microsoft .NET Framework Assistant 0.0.0. With those "disabled" (not uninstalled--the option was greyed out in both cases) the rogue script (from gissom.net) disappeared and redirection seemed to cease. It seems XULRunner 1.9.1 is the real culprit, as enabling that (and not the MS add-on) brought the script and redirections back. Maybe these installed themselves as soon as I installed Firefox?

    I found a similar problem with malware and XULRunner here:
    http://support.mozilla.com/tiki-vie...cale=en-US&comments_parentId=658523&forumId=1

    (I also gather the MS add-on may be worth uninstalling for other reasons.)

    Would uninstalling XULRunner fix my problems or do you think deeper cleaning is required?

    Thanks again.

    Yes this is why I was having you uninstall FireFox and said to delete the below folders
    This should remove all of the extensions and add-ons which was where I suspected the problem was. The problem was that you also had Mozilla Thunderbird installed and I had to be careful not to remove folders you needed for it. It would have been a much easier task to just delete all Mozilla applications and folders and then reinstall clean. Mozilla applications are frequent source of malware infections ( actually they are higher security risks and more problematic than IE is now). As the popularity of FireFox grew, hackers decided that it was worth attacking and thus all the security issues are no becoming apparent.

    Yes it should.

    Reading this mozzila support forum thread suggested that XULRunner was hiding in \Users\Family\AppData\Local\{Long-and-seemingly-random-string-of-values}, not in a folder marked as Firefox or Mozilla at all. It had a standard .rdf file that described it as relating to XULRunner, I deleted it, and the redirect seems to be gone from Firefox.

    Thanks again for all your help, and for the tips re: the risks of Mozilla software!

    chaslang MajorGeeks Admin - Master Malware Expert Staff Member

    Yes yours was likely in this one:
    C:\Users\Family\AppData\Local\{9D028924-2EB4-4AF2-8BF4-97640E815234}

    These are referred to as CLSIDs and malware uses random strings so it is next to impossible for us to know which ones are good vs bad. In addition since you had a 64 bit OS, some tools we normal could run that would help to find things like this could not be run. Such is the problem with x64.

    I suggest that you also delete the below which may be related:
    Code:
    ----a-w      0 2010-06-05 12:26:11  C:\Users\Family\AppData\Local\Dhevusudih.bin
    ----a-w  7,349 2010-05-28 20:02:00  C:\Users\Family\AppData\Local\evamifet.dll
    ----a-w    120 2010-06-05 12:26:15  C:\Users\Family\AppData\Local\Fgoqokoxev.dat
    ----a-w     20 2010-05-27 14:32:18  C:\Users\Family\AppData\Roaming\vqdlkr.dat
    
    You're welcome.




    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    3. Go back to step 6 oof the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
      related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of the READ ME
        for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    10. After doing the above, you should work thru the below link:
