My PC is now unable to get out on TCP/IP to the Internet. WHen I first start it up, it works, Then a few minutes later, TCP/IP does not work.
I am connected to a router and then a cable modem. The NIC icon shows good connectivity to the router. My ipconfig/all shows I have a valid IP address to the router.

Email fails with a TCP/IP error.
The web browser comes up with my home page but any other page I try to go to, nothing happens. No errors, nothing.

Ran Malware Bytes full scan - nothing found.
Ran Microsoft Security Essentials full sca- nothing found.
Also have SpyBot S&D and Ad-Aware running resident. They arent finding anything.

I changed my NIC card and when I booted with the new NIC, it worked fine all evening. Then the next morning, problem is back.

I am using another PC to write this.
thanks
R.

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up.

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.

  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

My problem is now worse. Now when I start up, I can not get out on the Internet at all whereas previously it would work for a few minutes. Now it is consistently broken. I get TCP/IP errors from my email OUtlook Express. Firefox just sits there and cant go anywhere.
I greatly appreciate any help you can provide.
thanks
R.

Hello, first of all completely uninstall your Norton antivirus as indicated below. You have two antivirus programs running at the moment which is not indicated and can cause many problems, including the ones you describe.

Please click HERE and follow the instructions in STEP 2 to download and run the norton removal tool.

regards, Elise

Hi Elise
OK All of Norton has been removed using the Norton Removal Tool.
Internet seems to be working (for now) but lets be sure.
What else would you like me to do?
thanks

Hi, glad to hear that!

Your version of Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system.
  • Download the latest version of Java Runtime Environment (JRE) Version 7u1.
  • Look for "JDK 7u1 (JDK or JRE).
  • Click the "Download JRE" button at the right.
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
    • Select "Windows x86 Offline" and click on jre-7-windows-i586.exe
  • Save it to your desktop
  • Close any programs you may have running - especially your web browser.
  • Uninstall all older versions of Java (any item with Java Runtime Environment, JRE or J2SE in the name).
  • Reboot your computer once all Java components are removed.
  • Install the newest version by double clicking (run as Administrator for Windows Vista/Seven) the downloaded file.



ESET ONLINE SCANNER
----------------------------
I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on this link to open ESET OnlineScan in a new window.
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on esetsmartinstaller_enu.exe to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image
      icon on your desktop.
  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
  • Click the Finish button.

regards, Elise

The ESETS scanner did not conclude as you described. It finished and did not find anything. All that was there was the FINISH button. There was no indication of exporting the results. I clicked FINISH expecting the export but it was completely over. Here is the log file I found in the ESETS directory.

That looks okay. :)

Please read these advices, in order to prevent reinfecting your PC:
  • Install and update the following programs regularly:
    • an outbound firewall. If you are connected to the internet through a router, you are already behind a hardware firewall and as such you do not need an extra software firewall.
      A comprehensive tutorial and a list of possible firewalls can be found here.
    • an AntiVirus Software
      It is imperative that you update your AntiVirus Software on regular basis.If you do not update your AntiVirus Software then it will not be able to catch the latest threats.
    • an Anti-Spyware program
      Malware Byte's Anti Malware is an excellent Anti-Spyware scanner. It's scan times are usually under ten minutes, and has excellent detection and removal rates.
      SUPERAntiSpyware is another good scanner with high detection and removal rates.
      Both programs are free for non commercial home use but provide a resident and do not nag if you purchase the paid versions.
    • Spyware Blaster
      A tutorial for Spywareblaster can be found here. If you wish, the commercial version provides automatic updating.
  • Keep Windows (and your other Microsoft software) up to date!
    I cannot stress how important this is enough. Often holes are found in Internet Explorer or Windows itself that require patching. Sometimes these holes will allow an attacker unrestricted access to your computer.
    Therefore, please, visit the Microsoft Update Website and follow the on screen instructions to setup Microsoft Update. Also follow the instructions to update your system. Please REBOOT and repeat this process until there are no more updates to install!!
  • Keep your other software up to date as well
    Software does not need to be made by Microsoft to be insecure. You can use the Secunia Online Software occasionally to help you check for out of date software on yourmachine.
  • Stay up to date!
    The MOST IMPORTANT part of any security setup is keeping the software up to date. Malware writers release new variants every single day. If your software updates don't keep up, then the malware will always be one step ahead. Not a good thing.
Some more links you might find of interest:
Please reply to this topic if you have read the above information. If your computer is working fine, this topic will be closed afterwards.

regards, Elise
