Suspected malware infection of my PC or router


Recommended Posts

Dear all,

My PC has been acting erratically and the following are the symptoms.

1) Sometimes when I go to a website, my browser will load up the web page then after awhile it will be redirected to another website. Usually it will just hang there while at the bottom left it will say "waiting for google-analytic.com"

2) Sometimes when there will be random warning telling me that my PC has virus/trojans, asking for permisiion to scan my PC. The exact wording of the warning is

Warning!!! Your computer contains various signs of viruses and malware programs presence. Your system requires immediate anti viruses check! Antivirus 2010 will perform a quick and free scanning of your PC for viruses and malicious programs. OK/Cancel

Even if I click cancel it will still proceed with scan and showing up lots of trojans on HDD (is it possible to still get infected if I click cancel or if I accidentally click OK?)

3) When clicking on a link sometimes a new browser opens up and it is attempting to connect to some weird websites.

4) I download and installed MBAM as a response to these erratic behavior but it wont let me update after installation (I read that some virus/trojans specifically attack MBAM)

I am using Avast! antivirus and Outpost firewall with regular windows update of OS (Win XP service pack 3). I recently performed a reformat of my PC but problem remains. The only non essential program files on my PC now is VLC video player, winamp, Starcraft 1 and 2. My room mates are also reporting similar problems and so I suspect a DNS infection of the router now. Please advice.

Thank you.

Regards,

Hi,

Before we begin, you should save these instructions in Notepad to your desktop, or print them, for easy reference. Much of our fix will be done with your internet connection disabled, so you will be unable to access this thread at that time. If you have questions at any point, or are unsure of the instructions, feel free to post here and ask for clarification before proceeding.

It sounds like a case of Zlob/DNSchanger that change the router's DNS settings.

1. Very important: First disconnect your computer from the internet.

2. Router Reset: Next you must reset the router to its default configuration. This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router. Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds).

3. Reset the IP/DNS settings of your interent connection:

  • Go to Start -> Control Panel -> Double click on Network Connections.
  • Right click on your default connection (usually Local Area Connection or Wireless Network Connection) and select Properties.
  • Select the General tab.
  • Double click on Internet Protocol (TCP/IP).
    • Under General tab:
      • Select "Obtain an IP address automatically".
      • Select "Obtain DNS server address automatically".

    [*]Click OK twice to save the settings.

    [*]Reboot if you had to change any setting.

4. Flush the DNS cache:

  • Click the Start logo in the bottom left corner of the screen
  • Click on Run
  • In the command window copy/paste the following:
    ipconfig /flushdns


  • Then hit enter.
  • Exit the command window.

5. Reconnect: Once you have followed all the above steps you can reconnect your computer to the internet.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Download ComboFix from one of these locations:

Link 1

Link 2

* IMPORTANT !!! Save ComboFix.exe to your Desktop

  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. Here is a guide on how to disable them:
    Click me
    If you can't disable them then just continue on.
  • Double click on ComboFix.exe & 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, 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 log in your next reply.
