Snip...

Please include the following reports for further review, and so we may continue cleansing the system:

C:\ComboFix.txt

New dds log.

Looks good! No more funky stuff getting launched, the item that started this whole thing is no longer in the registry and the DLL is no longer on the machine. Still, like my OS teacher in college used to say, the question is not whether or not you are paranoid; the questions is are you paranoid enough?

:)

Thanks, Carl

Hi again,

Disable Spybot's TeaTimer to make sure it won't interfere with fixes. You can re-enable it when you're clean again:

  • Run Spybot-S&D in Advanced Mode
  • If it is not already set to do this, go to the Mode menu
    select
    Advanced Mode

  • On the left hand side, click on Tools
  • Then click on the Resident icon in the list
  • Uncheck
    Resident TeaTimer
    and OK any prompts.
  • Restart your computer

Open notepad and copy/paste the text in the quotebox below into it:

Close all browser windows, disable protection software and refering to the picture above, drag CFScript into ComboFix.exe. Let ComboFix update itself.

Then post the resultant log & fresh dds.txt log.

I ran both, logs are attached. Unfortunately I forgot to update MBAM before running it, so I updated it and ran it a 2nd time. The 2nd run looked clean, and the output from KAS seems to have everything in quarantine or in an _restore directory. Light at the end of the tunnel, and it's not the headlight of an approaching train?

Kaspersky findings will be removed after ComboFix is uninstalled and system restore resetted (instructions below). Are you still noticing any problems? If not, it's time to secure your system to prevent against further intrusions.

THESE STEPS ARE VERY IMPORTANT

Let's reset system restore

Reset and Re-enable your System Restore to remove infected files that have been backed up by Windows. The files in System Restore are protected to prevent any programs changing those files. This is the only way to clean these files: You will lose all previous restore points which are likely to be infected. Please note you need Administrator Access to do clean the restore points.

1. Turn off System Restore.

On the Desktop, right-click My Computer.

Click Properties.

Click the System Restore tab.

Check Turn off System Restore.

Click Apply, and then click OK.

2. Reboot.

3. Turn ON System Restore.

On the Desktop, right-click My Computer.

Click Properties.

Click the System Restore tab.

UN-Check *Turn off System Restore*.

Click Apply, and then click OK.

NOTE: only do this ONCE,NOT on a regular basis

Now lets uninstall ComboFix:

  • Click START then RUN
  • Now copy-paste Combofix /uninstall in the runbox and click OK

Please download OTC and save it to desktop.

  • Double-click OTC.exe.
  • Click the CleanUp! button.
  • Select Yes when the
    Begin cleanup Process?
    prompt appears.
  • If you are prompted to Reboot during the cleanup, select Yes.
  • The tool will delete itself once it finishes, if not delete it by yourself.

Note: If you receive a warning from your firewall or other security programs regarding OTC attempting to contact the internet, please allow it to do so.

UPDATING WINDOWS AND INTERNET EXPLORER

IMPORTANT: You Need to Update Windows and Internet Explorer to protect your computer from the malware that is around on the Internet. Please go to the windows update site to get the critical updates.

If you are running Microsoft Office, or any portion thereof, go to the Microsoft's Office Update site and make sure you have at least all the critical updates installed (Free) Microsoft Office Update.

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.

The following are recommended third party programs that are designed to keep your computer clean. A link as well as a brief description is included with each item.

  • hosts file:
    • Every version of windows has a hosts file as part of them.
    • In a very basic sense, they are used to locate webpages.
    • We can customize a hosts file so that it blocks certain webpages.
    • However, it can slow down certain computers.
    • This is why using a hosts file is optional!!

    Download it here. Make sure you read the instructions on how to install the hosts file. There is a good tutorial here

    If you decide to download the hosts file, the slowdown problems can usually be avoided by following these steps:



    1. Click the start button (at the lower left hand corner of your screen)
    2. Click run
    3. In the dialog box, type services.msc
    4. hit enter, then locate dns client
    5. Highlight it, then double-click it.
    6. On the dropdown box, change the setting from automatic to manual.
    7. Click ok

    [*]Run Secunia vulnerability check here and fix its findings.

    [*]Get Anti Virus Software and keep it updated - Most AVs will update automatically, but if not I would recommend making updating the AV the first job every time the PC is connected to the internet. An AV that is using defs that are seven days old is not going to be much protection. If you do not update your anti virus software then it will not be able to catch any of the new variants that may come out. Good free antivirus programs are:

    Antivir

    Avast!

    Good commercial ones are from:

    Kaspersky and

    ESET

    [*]Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. 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. For more info, check this webpage out.

    If you don't have a 3rd party firewall or a router behind NAT then I recommend getting one. I recommend either Online Armor Free or Comodo Firewall Pro (If you choose Comodo: Uncheck during installation Install Comodo HopSurf.., Make Comodo my default search provider and Make Comodo Search my homepage and install firewall ONLY!). Both providers have support forums that help with configuration related questions.

Just a final reminder for you. I am trying to stress these two points.

UPDATE UPDATE UPDATE!!! Make sure you do this about every 1-2 weeks.

Make sure all of your security programs are up to date.

Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.

Once again, please post and tell me how things are going with your system... problems etc.

Have a great day,

Blade :)

Done! No more problems, I'm also now running Kaspersky Internet Security 2010. First thing I did after installing that was to update the DBs. There's one item in quarantine (dvdupgrrd.exe), but a full scan of the machine came back OK. I've moved as much data (i.e. non-executable files like photos) to a 2nd drive, and uninstalled everything I don't need/use. I have been running behind a Linksys firewall/router, is that considered sufficient? Also, is OTC something I can run on a regular basis? It seems pretty handy for reducing the amount of junk that a scan has to examine.

I also made sure everything was updated according to MS and Secunia. One thing I would like to get rid of is Outlook Express, since I'm running Office 2003 Pro and never use Express.

Thanks again for all your help, MBAM Pro is on the list of tools to get.

:)

You're welcome :)

Yes.

Also, is OTC something I can run on a regular basis? It seems pretty handy for reducing the amount of junk that a scan has to examine.

I'd recommend ATF Cleaner for cleaning not needed stuff.
