This has me stumped!
After removing a few different varieties of malware from the wife's laptop, including 3 strains of Vundo, the laptop (wireless connection) can no longer see the internet. The 'net was working fine until this. I'm thinking there may still be some sort of infection.
Edit to add info: Internet was working until SuperAntiSpyware was used to remove the Vundo strains along with 2-4 other items. It was after this that the problem started. I removed SAS afterward (leaving the logs and quarantine in place), thinking that it was causing the problem, but to no avail. I'll add in exactly what SAS found here in an edit.
The funny thing is - the laptop hooks up to the wireless router just fine, my PC and the laptop can see each other and transfer files, and the laptop can PING IP addresses (numbers) with no problem. It -cannot- ping by name, which indicates to me that the domain name resolution somehow got hosed.
I've tried the various winsock fixes, rebuilding the tcp/ip stack, flushing the DNS cache, checking all the settings - you name it. The ipconfig /all command report even looks good (all IP numbers correct).
As far as I can tell, the laptop is apparently clean now, but I could still be missing something due to the 'net issues.
Thanks in advance for any assistance!
Floyd.

Edit to add: Laptop is Windows XP Home, SP3

Have you run MBAM on here??
If you cannot use the Internet,you will need access to another computer that has a connection.
From there save mbam-setup.exe to a flash,usb,jump drive or CD. Now transfer it to the infected machine, then install and run the program.
If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe so it will install on the hard drive.
***
Manually Downloading Updates:
Manually download them from HERE and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.


Note: Mbam-rules.exe is not updated daily. Another way to get the most current database definitions if you're having problems updating through the program's interface or have already manually downloaded the latest definitions (mbam-rules.exe) shown on this page, is to do the following: Install MBAM on a clean computer, launch the program and update through MBAM's interface. Copy the definitions (rules.ref) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system. If you cannot see the folder, then you may have to Reconfigure Windows to show it.
  • XP: C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware
  • Vista: C:\Documents and Settings\Users\All Users\Malwarebytes\Malwarebytes' Anti-Malware

I was able to fix the 'net problem by disabling "DNS Client" (IIRC) in services.msc, however I'm still having other odd issues that may or may not be malware related.
One of the problems is this: http://www.bleepingcomputer.com/forums/t/324026/cds-dvds-cant-be-read/
I'm able to run and update MBAM, so if you let me know what scan parameters you need for a report, I can have something posted for you tomorrow afternoon.
I'd really like to make sure the system is clean before I start blaming registry issues or other Windows shenanigans for its problems :thumbsup:
Thanks for looking into this!
Floyd.

[TFC by OT
Please download TFC by Old Timer and save it to your desktop.
alternate download link
Save any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
b]Next run MBAM (MalwareBytes):[/b]

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.alternate download link 1
alternate download link 2
MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.
We may as well do an online scan also,,,ESET
Please perform a scan with Eset Online Antiivirus Scanner.
(Requires Internet Explorer to work. If given the option, choose "Quarantine" instead of delete.)
Vista users need to run Internet Explorer as Administrator. Right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run as Administrator from the context menu.
  • Click the green ESET Online Scanner button.
  • Read the End User License Agreement and check the box: YES, I accept the Terms of Use.
  • Click on the Start button next to it.
  • You may receive an alert on the address bar that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then click Insall ActiveX component.
  • A new window will appear asking "Do you want to install this software?"".
  • Answer Yes to download and install the ActiveX controls that allows the scan to run.
  • Click Start.
  • Check Remove found threats and Scan potentially unwanted applications.
  • Click Scan to start. (please be patient as the scan could take some time to complete)
  • If offered the option to get information or buy software. Just close the window.
  • When the scan has finished, a log.txt file will be created and automatically saved in the C:\Program Files\ESET\ESET Online Scanner\log.txt
    folder.
  • Click Posted Image > Run..., then copy and paste this command into the open box: C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • The scan results will open in Notepad. Copy and paste the contents of log.txt in your next reply.
Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

Well obviously no we need a deeper look. Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.

Thank you!!
Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
