I picked up a nasty virus last night. It started out as the usual system security rouge. I cleaned that with a process stop and Malware Bytes. After several reboots and scans with McAfee, MalwareBytes, and Kaspersky the virus in still there.

Symptoms: Google link hijacking and ???

From Kaspersky:
detected: Trojan program Trojan.Win32.Monder.cqbi File: globalroot\systemroot\system32\geyekrqgrrrqpn.dll
It claims the file is locked and will not delete

Malware Bytes
Memory Modules Infected:
\\?\globalroot\systemroot\system32\geyekrqgrrrqpn.dll (Trojan.TDSS)
Files Infected:
\\?\globalroot\systemroot\system32\geyekrqgrrrqpn.dll (Trojan.TDSS) -> No action taken.
Malwarebytes trys to delete after reboot but it does not seem to be successfull

Hello you are right..

IMPORTANT NOTE: It is a nasty variant of the TDSSSERV rootkit component. Rootkits, backdoor Trojans, Botnets, and IRC Bots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. Rootkits are used by Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:

What danger is presented by rootkits?
Rootkits and how to combat them
r00tkit Analysis: What Is A Rootkit

If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised and change each password using a clean computer, not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
What Should I Do If I've Become A Victim Of Identity Theft?
Identity Theft Victims Guide - What to do


Although the infection has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if the malware appears to have been removed. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired so you can never be sure that you have completely removed a rootkit. The malware may leave so many remnants behind that security tools cannot find them. Tools that claim to be able to remove rootkits cannot guarantee that all traces of it will be removed. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

When should I re-format? How should I reinstall?
Help: I Got Hacked. Now What Do I Do?
Where to draw the line? When to recommend a format and reinstall?


Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. Some infections are difficult to remove completely because of their morphing characteristics which allows the malware to regenerate itself. Sometimes there is another hidden piece of malware which has not been detected by your security tools that protects malicious files and registry keys (which have been detected) so they cannot be permanently deleted. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a DDS/HijackThis log for further investigation. Let me know how you wish to proceed.

========================
It doesn't say what your Operating system is (XP<Vista etc)
Now your MBAm(Malwarebytes scan said no action taken.. So if we are to clean and not format we need to rerun that.
Rerun MBAM like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan.
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

I am running XP with the latest SP and patches. I forgot to add one more thing. I can't boot into safe mode no matter what - very strange...

OK that was good. I'm hoping you can run these now.
Next run ATF and SAS:

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware

, Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you

should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.


Please ask any needed questions,post logs and Let us know how the PC is running now.
