I had some viruses and I successfully removed them with Kaspersky. Malwarebytes said there were no problems. During that time I was unable to visit any websites of which one was and still is facebook. I checked the hosts file and nothing is there. I found the problem in the dns where there are many facebook entries. When I do a dnsflush, the entries remain and the problem persists. Here are my logs.

In my original post, I attached a zip file and inside that zip file are 4 files. One of them is the dds scan.

Hi, sorry about that. Due to the title of the attachment I assumed they were MBAM logs. :)

COMBOFIX
---------------
Please download ComboFix from one of these locations:
Bleepingcomputer
ForoSpyware
  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on Combofix.exe and follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, or if you are running Vista, ComboFix will continue it's malware removal procedures.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\Combofix.txt in your next reply.

Ok some interesting things. I said I didn't have recovery console even though I did. I tried to use it's install feature but it said I had no internet so I manually created a restore point and went ahead with the process. It fixed the problem but I am not able to use the default dns servers. I went ahead and put in google dns servers and it works but without them I have no internet all. I would like the default dns servers to work. Note that I tried switching the dns server before and it did nothing so something has definitely changed here. My log is attached.

If you connect through a router, please reset it. You can do this by pressing the reset button for approx. 10 seconds with the router powered off. Let me know if that takes care of the DNS problem.

Besides this, do you have any other issues left?

I'm glad to hear that! :) To be sure everything stays okay, here are a few last steps.

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 7.
  • Look for "JDK 7 (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.

My apologies, I missed your reply. These files were just some remnants.

ALL CLEAN
--------------
Your machine appears to be clean, please take the time to read below on how to secure the machine and take the necessary steps to keep it clean :)

Please do the following to remove the remaining programs from your PC:
  • Delete the tools used during the disinfection:
  • Click start > run and type combofix /uninstall, press enter. This will remove Combofix from your computer.
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.
