Have a friends computer and am fighting with it right now. The computer says I do have both wireless and wired network connection but I am unable to connect to the internet. I downloaded malwarebytes and installed it but was not able to update it as the internet is not working for me right now. I did a quick scan and that got rid of 43 problems but I am still unable to connect to the internet. As I write this, I am running a full scan to see if that will help.

Any suggestions on your side?

Appreciate any help,
Jeff

Hi,

After performing these scans, enter the results in your next post and also update me on the status of the PC.

Note: You may have to perform some or all of the following in Safe Mode With Networking, depending on if you have internet access while in the normal Windows environment.

================================================================================

Download Security Check by screen317 from here or here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.

================================================================================

Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
    For instructions with screenshots, please refer to the How to use SUPERAntiSpyware to scan and remove malware from your computer Guide.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all other options as they are set):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the Control Center screen.
  • Back on the main screen, under "Select Scan Type" check the box for Complete Scan.
  • If your computer is badly infected, be sure to check the box next to Enable Rescue Scan (Highly Infected Systems ONLY).
  • Click the Scan your computer... button.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the scan log after reboot, launch SUPERAntiSpyware again.
  • Click the View Scan Logs button at the bottom.
  • This will open the Scanner Logs Window.
  • Click on the log to highlight it and then click on View Selected Log to open it.
  • Copy and paste the scan log results in your next reply.
-- Some types of malware will disable security tools. If SUPERAntiSpyware will not install, please refer to these instructions for using the SUPERAntiSpyware Installer. If SUPERAntiSpyware is already installed but will not run, then follow the instructions for using RUNSAS.EXE to launch the program.
================================================================================

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Super AntiSpyware:

file was too long to post. This site told me to shorten it. Is there a way to attach the file so you can see it?

As for the computer, it still does not have internet connection either normal or safe mode. It will not connect with my wireless adapter or through ethernet.

Let me know if I can upload the superantispyware file to you,

Thanks,
Jeff

The SAS log shouldn't be that long. :blink:

I suppose we will do without it for now.

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

Are you experiencing any other symptoms other than a lack of internet connection?

Also, have you tried installing the latest drivers for the network adapter off the manufacturer site?

The SAS log is 164 KB. It is a large text file. I will try to locate drivers for this computer and get back to you. As for now, the Device Manager says the device is working properly but I don't have an internet connection.

I'll check on any new drivers

I am pretty busy for the rest of the night with my studies, so I'll leave another suggestion. But you should still install drivers.

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

TCP/IP stack repair options for use with Vista or Windows 7

Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type the following commands, each followed by the Enter key:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults: netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults: netsh int ipv6 reset reset.log

Reboot the machine.

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

TCP/IP stack repair options for use with Windows XP with SP2/SP3

Start, Run, CMD to open a command prompt:

In the command prompt window that opens, type the following commands, each followed by the Enter key:

Note: Type only the text in bold for the following commands.

Reset TCP/IP stack to installation defaults, type: netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog

Reboot the machine.

Tried your last suggestion and that didn't work either. I uninstalled the driver and then had it reinstall and still no internet. The driver that is on the computer was the latest driver out there. When I check the local connection and click on the support tab, I noticed that there at no numbers by the IP address, Submask or Default gateway.

Talk to you soon,
Jeff

Please follow the instructions in ==>This Guide<== starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
