Hello all. My Windows 7 (32-bit) computer is infected with an 'X' that is redirecting Google clicked searches in FireFox. Internet Explorer does not seem to be impacted, but I am not 100% on this, but I never see redirects in IE, only Firefox.

I appreciate any experts help to resolve the issue, I have been beating my head against the wall for 2 weeks. Here is what I have done:

1. Avast does not find anything
2. Ran HiJackThis and looked for something bad. Can post logs at request.
3. Try to Run ComboFix, but it never gets past: "However, scan times for badly infected machines may easily double" and PC completely locks up. I watched Task Manager close by itself today.
4. Saw a process when Combofix was running called WBVista.exe, not sure if this is something that should be there.
5. Tried GMER, does not find rootkit, but I will post log.
6. RootRepeal -- will not run
7. MBRCheck -- "Windows 7 MBR Code Detected" in green
8. Many other online virus scanners, Search and Destroy, TrendMicro, Sophos...
9. Computer has already ran Defogger, is in Disabled state.

Note: I ran the above before I found this forum which instructs not to run some of the utilities. I will refrain in future.

Thanks ahead of time for the brave soul that tries to help me.

UPDATE: Per Instructions, I tried to run DDS to generate a log, but it locked up PC completely. I am attempting to generate a GMER log right now.
UPDATE2: Ran GMER, attached is log file.

Hello

I Would like you to do the following.

Please print out or make a copy in notpad of any instructions given, as sometimes it is necessary to go offline and you will lose access to them.

Run Combofix:

You may be asked to install or update the Recovery Console (Win XP Only) if this happens please allow it to do so (you will need to be connected to the internet for this)

Before you run Combofix I will need you to turn off any security software you have running, If you do not know how to do this you can find out >here< or >here<

Combofix may need to reboot your computer more than once to do its job this is normal.

You can download Combofix from one of these links. I want you to save it to the desktop and run it from there.
Link 1
Link 2
Link 3
1. Close any open browsers or any other programs that are open.
2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Double click on combofix.exe & follow the prompts.
When finished, it will produce a report for you.

Note 1: Do not mouseclick combofix's window while it's running. That may cause it to stall

Note 2: If you recieve an error "Illegal operation attempted on a registery key that has been marked for deletion." Please restart the computer

"information and logs"

  • In your next post I need the following
  • Log from Combofix
  • let me know of any problems you may have had
  • How is the computer doing now?

ComboFix locks up computer every time, it will not complete scan.

I found the XULRunner problem described at the link below on my computer and removed the firefox extension, directory on "C:\...\" and registry key, however, i still do not know how it is getting on the computer from the start.

  • If a suspicious file is detected, the default action will be Skip, click on Continue.
  • It may ask you to reboot the computer to complete the process. Click on Reboot Now.

It was either the XULRunner problem in the link below or combofix fixed it. I examined the javascript code that is behind the XULRunner infection and it definitely was redirecting google searches. There is a separate file that contains 2 encoded variables and if you decode the data the links go directly to the websites I was being redirected to. An interesting bit of malware that is not detected by anything yet. How it got loaded, I have no idea.

Did you see anything in ComboFix logs that got removed? Do I still need to run tdsskiller?
