Hello:

A coworker went to some bad sites and got there PC all messed up.

We run Symantec Corporate, so that is the antivirus program that was used to do the AV scans.

I followed the instructions in the malware removal thread. Attached are the 3 log files.

PandaAntiRootkit came up clean.

We do run SAAZ monitoring software on all of our PCs for remote network support.

Thanks!!
 
looks like the steps did what they are supposed to do.

It also looks like somebody likes playing games -

Let's run an online scan to see if I missed anything -

Run Kaspersky Online AV Scanner

Order to use it you have to use Internet Explorer.
Go to Kaspersky and click the Accept button at the end of the page.

Note for Internet Explorer 7 users: If at any time you have trouble with the accept button of the licence, click on the Zoom tool located at the right bottom of the IE window and set the zoom to 75 %. Once the license accepted, reset to 100%.
  • Read the Requirements and limitations before you click Accept.
  • Allow the ActiveX download if necessary.
  • Once the database has downloaded, click Next.
  • Click on "My Computer"
  • When the scan has completed, click Save Report As...
  • Enter a name for the file in the Filename: text box and then click the down arrow to the right of Save as type: and select text file (*.txt)
  • Click Save - by default the file will be saved to your Desktop, but you can change this if you wish.
Attach the report into your next reply


If the kaspersky log checks out then we can clean up, remove backups, and secure the work you did already
 
Thanks for your help!

Looks like Kaspersky found a couple of things. 2 In old Symantec Quarantine and several of the clean up tools. Also found 2 others that were missed by Symantec.

Here is the log.
 
Obviously you want to clean out Symantec Quarantine

but...

Asterisk Logger: Reveal/recover password behind asterisks (***)

Do you use that program? Or would you like to remove it?

I would like to hope that you or your coworker installed it rather than an infection.
 
Thanks alot for your help!

The logger was installed by a network contracter, not by malware. He should have removed it.
 
How is the computer running? any symptoms left?

Looks like they removed the program but not the zip of the installer

Just delete these then empty the recycle bin:

C:\BackUp of Files\Other\astlog.zip
C:\Documents and Settings\mstraub\Desktop\Other\astlog.zip

------------------------------------------------------------------

Uninstall Combofix
* Click START then RUN
* Now type Combofix /u in the runbox
* Make sure there's a space between Combofix and /u
* Then hit Enter.

* The above procedure will:
* Delete the following:
* ComboFix and its associated files and folders.
* Reset the clock settings.
* Hide file extensions, if required.
* Hide System/Hidden files, if required.
* Set a new, clean Restore Point.

-----------------------------------------------------------------------

OTCleanit! by Oldtimer
  • Download OTCleanIt
  • Click the CleanUp! button.
    • It will go thorugh the list and remove all of the tools it finds and then delete itself (requiring a reboot).

---------------------------------------------------------------------------

Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:
  1. Set correct settings for files
    • Click Start > My Computer > Tools menu (at top of page) > Folder Options > View tab.
    • Under "Hidden files and folders" if necessary select Do not show hidden files and folders.
    • If unchecked please check Hide protected operating system files (Recommended)
    • Click OK

    clear system restore points

    • This is a good time to clear your existing system restore points and establish a new clean restore point:
      • Go to Start > All Programs > Accessories > System Tools > System Restore
      • Select Create a restore point, and Ok it.
      • Next, go to Start > Run and type in cleanmgr
      • Select the More options tab
      • Choose the option to clean up system restore and OK it.
      This will remove all restore points except the new one you just created.

  2. Make your Internet Explorer more secure - This can be done by following these simple instructions:
    1. From within Internet Explorer click on the Tools menu and then click on Options.
    2. Click once on the Security tab
    3. Click once on the Internet icon so it becomes highlighted.
    4. 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.
    5. Next press the Apply button and then the OK to exit the Internet Properties page.
  3. Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

    See this link for a listing of some online & their stand-alone antivirus programs:

    Virus, Spyware, and Malware Protection and Removal Resources

  4. Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

  5. 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 succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

    For a tutorial on Firewalls and a listing of some available ones see the link below:

    Understanding and Using Firewalls

  6. 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.This is done in Vista through control panel -> windows updates.

  7. Install Spybot - Search and Destroy - Install and download Spybot - Search and Destroy with its TeaTimer option. This will provide realtime spyware & hijacker protection on your computer alongside your virus protection. You should also scan your computer with program on a regular basis just as you would an antivirus software.

    A tutorial on installing & using this product can be found here:

    Using Spybot - Search & Destroy to remove Spyware , Malware, and Hijackers

  8. Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

    A tutorial on installing & using this product can be found here:

    Using SpywareBlaster to protect your computer from Spyware and Malware

  9. Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
Follow this list and your potential for being infected again will reduce dramatically.

here are some additional utilities that will enhance your safety

  • IE/Spyad <= IE/Spyad places over 4000 websites and domains in the IE Restricted list which will severely impair attempts to infect your system. It basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.
  • MVPS Hosts file <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your coputer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
  • Google Toolbar <= Get the free google toolbar to help stop pop up windows.
  • Winpatrol <= Download and install the free version of Winpatrol. a tutorial for this product is located here:
    Using Winpatrol to protect your computer from malicious software
 
Looks good, well-done Blind Dragon.
I can do these logs now, i have found out how to analyse them...
 
Everything seems fine accept for a small issue in Outlook 2000. It bombs whenever the user tries to access to the Tools->Customize option. I am likely going to just uninstall and reinstall that application.

Thanks again for all of your help. I followed all the steps in your follow up guide and I also installed Firefox and told my user to use that browser.
 
Within firefox you can select tools -> add-ons -> get addons -> browse all addons -> you can get and IE Tab for sites that demand IE and you can run IE within firefox browser
