Ok, went through and cleaned out what I found via other posts...had a lot of ancient items to get rid of as well. Pretty sure it might all be corrected, currently rescanning with fingers crossed.

Hi,

Let's make sure you are totally clean,

please run the following;

Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.

  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

  • Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Posted Image

  • Click on Yes, to continue scanning for malware.
When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.

Hi

Please do the following:

  • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before following the steps below.
  • They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
Copy/paste the text inside the Codebox below into notepad:

Here's how to do that:
Click Start > Run type Notepad click OK.
This will open an empty notepad file:

Copy all the text inside of the code box - Press Ctrl+C (or right click on the highlighted section and choose 'copy')

DDS::
uInternet Settings,ProxyServer = http=localhost:8080
uInternet Settings,ProxyOverride = <local>

FireFox::
FF - prefs.js: keyword.URL - hxxp://www.mywebsearch.com/jsp/cfg_redir2.jsp?id=ZRfox000&fl=0&ptb=B3TVLi1GzKHYuZeHgR4Nzg&url=http://search.mywebsearch.com/mywebsearch/dft_redir.jhtml&st=kwd&searchfor=

ClearJavaCache::

Now paste the copied text into the open notepad - press CTRL+V (or right click and choose 'paste')

Save this file to your desktop, Save this as "CFScript"


Here's how to do that:

1.Click File;
2.Click Save As... Change the directory to your desktop;
3.Change the Save as type to "All Files";
4.Type in the file name: CFScript
5.Click Save ...

Posted Image
  • Referring to the screenshot above, drag CFScript.txt into ComboFix.exe.
  • ComboFix may request an update; please allow it.
  • ComboFix will now run a scan on your system. It may reboot your system when it finishes. This is normal.
  • When finished, it shall produce a log for you.
  • Copy and paste the contents of the log in your next reply.

CAUTION: Do not mouse-click ComboFix's window while it is running. That may cause it to stall.

**Note**

When CF finishes running, the ComboFix log will open along with a message box--do not be alarmed. With the above script, ComboFix will capture files to submit for analysis.
  • Ensure you are connected to the internet and click OK on the message box.
