Here you go, here's the Fix Log and the OTL Log.
One thing I noticed in glancing over the fix log is that there's a user account on my system named "Updatus User". It's not listed under user accounts in my control panel, and it doesn't seem to have any files of its own. It also doesn't seem to have any permissions, so I'm not too worried about it, just curious if you know what this could be.

Hi,

NVIDIA Corporation will creates an account named "Updatus User" so that it will already have permissions on your system and updates will perform smoothly.
-----------

I see that you have Malwarebytes already on your computer.  Please open Malwarebytes, update it and then run a Quick Scan.  Save the log that is created for your next reply.
----------

ESET Online Scanner:

Hi,

The two entries that were found by ESET are already quarantined by ComboFix so they are fine. 

Please open OTL.

  • Make sure all other windows are closed and to let it run uninterrupted.
  • When the window appears, click the None button near the top (it may looked greyed out)
  • In the Extra Registry section change it to All
  • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
When the scan completes, it will open 2 notepad windows, OTL.Txt and Extra.txt. Please post the Extra.txt.

    click Remove Older Versions.

Hi there,
followed those steps, everything worked fine. Do you need a copy of the removal log from JavaRa?
Everything seems to be running perfectly, no problems at all so far!

No thank you.   :)
----------

Provided that there are no other problems...

IT APPEARS THAT YOUR LOGS ARE NOW CLEAN :)  SO LETS DO A COUPLE OF THINGS TO WRAP THIS UP!! :)

This infection appears to have been cleaned, but I can not give you any absolute guarantees.  As a precaution, I would go ahead and change all of your passwords as this is especially important after an infection.
----------

The following will implement important cleanup procedures as well as reset System Restore points:

Click Start > Run  and copy/paste the following bolded text into the Run box and click OK:

ComboFix /Uninstall
----------

Clean up with OTL:
  • Double-click OTL.exe to start the program.
  • Close all other programs apart from OTL as this step will require a reboot
  • On the OTL main screen, press the CLEANUP button
  • Say Yes to the prompt and then allow the program to reboot your computer.
----------

Any of the logs that you created for use in the forums or remaining tools that have not yet been removed can be deleted so they aren't cluttering up your desktop.

Here are some tips to reduce the potential for spyware infection in the future:

1. Make your Internet Explorer more secure - This can be done by following these simple instructions:
  • From within Internet Explorer click on the Tools menu and then click on Options.
  • Click once on the Security tab
  • Click once on the Internet icon so it becomes highlighted.
  • Click once on the Custom Level button.
  • Change the Download signed ActiveX controls to Prompt
  • Change the Download unsigned ActiveX controls to Disable
  • Change the Initialize and script ActiveX controls not marked as safe to Disable
  • Change the Installation of desktop items to Prompt
  • Change the Launching programs and files in an IFRAME to Prompt
  • Change the Navigate sub-frames across different domains to Prompt
  • When all these settings have been made, click on the OK button.
  • If it prompts you as to whether or not you want to save the settings, press the Yes button.
  • Next press the Apply button and then the OK to exit the Internet Properties page.
Make your Mozilla Firefox more secure - This can be done by adding these add-ons:
2. Enable Protected Mode in Internet Explorer.  This helps Windows Vista users stay more protected from attack by running Internet Explorer with restricted privileges as well as reducing the ability to write, alter or destroy data on your system or install malicious code.  To make sure this is running follow these steps:
  • Open Internet Explorer
  • Click on Tools > Internet Options
  • Press Security tab
  • Select Internet zone then place check next to Enable Protected Mode if not already done
  • Do the same for Local Intranet, Trusted Sites and Restricted Sites and then press Apply
  • Restart Internet Explorer and in the bottom right corner of your screen you will see Protected Mode: On showing you it is enabled.
3. Use and update an anti-virus software - I can not overemphasize the need for you to use and update your anti-virus application on a regular basis.  With the ever increasing number of new variants of malware arriving on the scene daily, you become very susceptible to an attack without updated protection.

4. Firewall
Using a third-party firewall will allow you to give/deny access for applications that want to go online. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a firewall in its default configuration can lower your risk greatly.  A tutorial on firewalls can be found here.  **There are firewalls listed in this tutorial that could be downloaded and used but I would personally only recommend using one of the following two below:
Online Armor Free
Agnitum Outpost Firewall Free

5. Make sure you keep your Windows OS currentWindows XP users can visit Windows update   regularly to download and install any critical updates and service packs. Windows Vista/7 users can open the Start menu > All Programs > Windows Update > Check for Updates (in left hand task pane) to update these systems.  Without these you are leaving the back door open.

6. Consider a custom hosts file such as MVPS HOSTS. This custom hosts file effectively blocks a wide range of unwanted ads, banners, 3rd party Cookies, 3rd party page counters, web bugs, and many hijackers.  For information on how to download and install, please read this tutorial by WinHelp2002
Note: Be sure to follow the instructions to disable the DNS Client service before installing a custom hosts file.

7. WOT (Web of Trust) As "Googling" is such an integral part of internet life, this free browser add on warns you about risky websites that try to scam visitors, deliver malware or send spam. It is especially helpful when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites.  WOT has an add-on available for Firefox, Internet Explorer as well as Google Chrome.

8.Finally, I strongly recommend that you read TonyKlein's good advice So how did I get infected in the first place?

Please reply to this thread once more if you are satisfied so that we can mark the problem as resolved.
