Google 18.104.22.168 Redirect Malware, Virus, Spyware…
UPDATE (9/29/2011 9:15AM EST)
I have corrected the link to the 7770finder.exe file. This still detects the original strain of this piece of malware. To fully innoculate and protect yourself, I recommend downloading Malwarebytes’ Anti-Malware software:http://www.malwarebytes.org/. It’s FREE for personal use!

I’ve been getting a lot of email questioning why my tool did not remove found infected files. This tool does NOT remove any infected files. It is up to you to remove them. This tool also does not support directory recursion; e.g., it ONLY scans %SystemDir% files, no subfolders. Sorry.

To help prevent infection take the following actions:
Use NoScript Firefox Plugin

Malwarebytes is able to detect the malware. Interestingly enough, it only detects it if it’s in c:windowssystem32drivers folder. I’m not sure what’s up with that. Update the applications to ensure you’re using the latest definitions. If you know of any other Spyware/Malware/AV software that is detecting this, leave a comment.
AVG supposedly detects this threat (posted by: Peter Liu)
Please let me know of any other software that detects this.
1) Redirects searches to 22.214.171.124
2) Displays what appear to be normal results, but in fact are linked to many other malware centric sites
3) Kaspersky (as of this writing) is the only application to detect the presence of this malware on your PC (and yes I’ve tried Malware Bytes, Spybot S&D, AntiVir, SuperSpyware)
4) The culprit file resides in c:\windows\system32\wdmaud.sys and should be removed, or renamed. Don’t remove the file from c:\windows\system32\drivers\wdmaud.sys.
5) After deleting/renaming the file, restart your browser(s) and you’ll be OK. Note: This affects IE and FF, I have not tested Opera, Netscape or Safari.
Here’s an example screenshot of what Google results look like when you are infected. Notice the Google links (green links) on the results page.
What I’d like to know is what that file has to do with the browser. The WDMAUD.sys file (the real one) deals with Windows High Definition Audio. Could this file have been placed there via Flash vulnerability? I know I was on YouTube the night prior to me being invaded.
I ran ProcessMon from SysInternals and saw that Firefox and IE both called for wdmaud.sys but in the c:\windows\system32 directory, not in the drivers subfolder. Here’s a screenshot of that. If I move the file (the infected file) out of system32 the redirection stops. If I put it back in the infection is back. My question that is burning me is HOW did it get there? What put it there?
Process Monitor highlighting the search request for wdmaud.sys
So far, the infection is in c:\windows\system32\wdmaud.sys (or c:\winnt\system32\wdmaud.sys). Simply delete the file and restart any open web browsers.
If you do not find the wdmaud.sys file, or are unsure what to even look for, you may download a tool that we created that will investigate all the files in the Windows system directory. It doesn’t just specifically look for the wdmaud.sys file, but it looks for the signature in every file within that directory.
Compatible with: Windows XP (all SPs), Server 2000/2003/2008, and Vista.
Your use of this software indicates that you agree to the attached terms of service.
Tool Update (1/16/2009)
* Prints path of file that is infected
* Allows program to accept a path as an argument; otherwise it uses %SystemDir% as default if no path specified
* Still no recursion -yet-
If you download the tool and find it useful, or don’t find it useful, I’d appreciate any feedback. You can leave a comment or send any questions/comments to email@example.com.
