Hi. I originally posted this problem on 7/14/09 and never received any advice. A few lookers but no replies. I still have no internet connectivity on this machine so unless I can create a bootable cd I can't get any tools to run to clean it up. I did get the paid version of AVG 8.5 to load off a cd and it reports 5 instances of win.32 huer on the machine. They are supposed to be locked in the AVG virus vault. I know earlier versions of AVG were giving false positives for this trojan but I tend to believe this report since the machine is screwed up. Since removing the virus without any tools is impossible can any one advise me on how to restore internet connectivity? Or can I use this machine running XP pro sp2 to load a cleaner to the infected machine? They share the same WLAN I know you guys are busy but a little advice sure would be appreciated.

Thanx again in advance
Steve

Hello,I've a couple ideas.

See if this fixes your Net issues .

Go to Start ... Run and type in cmd
A dos Window will appear.
Type in the dos window: netsh winsock reset
Click on the enter key.

Reboot your system to complete the process.


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.

***


Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware 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.

Thanks for your' reply I was beginning to think my problem was so obviously simple no one wanted to respond. Regardless, I have been acting on your suggestions most of the afternoon with no results. The reset at the DOS command prompt comes back as reset completed successfully but I still can't get a connection.. I performed the reset hard wired to the router and via the wireless adapter card in both normal and safe modes. I checked the wireless connection through the icon in the start tray and it comes back as "good with limited access" Does this mean spam is going out and nothing can get in? Neither Firefox or IE8 browsers come up. The windows firewall is still turned off and resists all attempts to turn it back on. I copied the latest update from MBAM to cd and ran the quick scan. The report came back "No malicious items detected." The full scan is running as I type this and I will post the results if there are any. Do you have any further suggestions in the mean time? I can usually clear these things up in a few hours but this one really has me frustrated. I am into the third day on this and have just about run out of ideas. Any and all suggestions are welcome.

Thanks Again
Steve

Try this--open control, internet options, connections tab, lan settings, uncheck the box next to "use proxy...."

Please go to Start -> Control Panel, and choose Network Connections. Then right click on your default connection, usually Local Area Connection or Dial-up Connection if you are using Dial-up, and left click on properties. Double-click on the Internet Protocol (TCP/IP) item and select the radio button that says Obtain DNS servers automatically. Click OK twice, and restart your computer.
