My laptop started running really slow and freezing up a couple of days ago. I ran Ad-Aware and it detected win32.trojan.dnschanger. I opted for Ad-Aware to remove it but I'm thinking that didn't work...

The file was associated with a Family Feud game I'd downloaded through my HP game console recently. Go figure.

Now, Firefox won't open at all, and IE just loads a page that says Insecure Internet Activity. Threat of virus attack.

I don't know what to do next. I want to make sure I get rid of it completely, so I'm hoping you can help. Thanks in advance!

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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 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.
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 and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes.


* If you cannot use the Internet or download any programs from your machine, you are going to need access to another computer (family member, friend, etc) with an Internet connection. Save mbam-setup.exe to a flash (usb, pen, thumb, jump) drive or CD, transfer it to the infected machine, then install and run the program. If you cannot transfer or install from the infected machine, try running the setup (installation) file directly from the flash drive or CD so it will install on the hard drive.

Your MBAM log shows "No action taken". This usually occurs if you forget to click "Remove Selected" and instead just click "Save Logfile". Please review these instructions (scroll down), rescan again (Quick Scan) in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. After performing a new scan, click the Logs tab and copy/paste the contents of the new report in your next reply.

Lets do another scan to see if we find anything else that MBAM may have missed.

Seems to be running much better! The only thing I'm picking up now is the occasional tracking cookies. Thanks again for your help!

Cookies are text string messages given to a Web browser by a Web server. Whenever you visit a web page or navigate different pages with your browser, the web site generates a unique ID number which your browser stores in a text (cookie) file that is sent back to the server each time the browser requests a page from that server. Cookies allow third-party providers such as ad serving networks, spyware or adware providers to track personal information. The main purpose of cookies is to identify users and prepare customized Web pages for them.

The type of cookie that is a cause for some concern are "tracking cookies" because they can be considered a privacy risk. These types of cookies are used to track your Web browsing habits (your movement from site to site). Ad companies use them to record your activity on all sites where they have placed ads. They can keep count of how many times you visited a web page, store your username and password so you don't have to log in and retain your custom settings. When you visit one of these sites, a cookie is placed on your computer. Each time you visit another site that hosts one of their ads, that same cookie is read, and soon they have assembled a list of which of their sites you have visited and which of their ads that you have clicked on. They are used all over the Internet and advertisement companies often plant them whenever your browser loads one of their banners. Cookies are NOT a "threat". As text files they cannot be executed to cause any damage. Cookies do not cause any pop ups nor do they install malware.

As long as you surf the Internet, you are going to get cookies and some of your security programs will flag them for removal. However, you can minimize this by reading "Blocking & Managing Unwanted Cookies" and "Block Third-Party Cookies in IE7".

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Tips to protect yourself against malware and reduce the potential for re-infection:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".

• Avoid gaming sites, underground web pages, pirated software sites, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Welcome to BC

I'm glad your problem has been resolved. However, it's not a safe practice to be following specific instructions provided to someone else. Instructions given to others have been formulated to fix that particular members problems, NOT YOURS after careful evaluation of the malware involved. Although your problem may be similar, the solution could be different based on the kind of hardware, software, system requirements, etc. and the presence of other malware. Using someone else's fix instructions could lead to disastrous problems with your operating system.

If you need assistance in the future, it's best that you tell us what specific issues YOU are having rather than point to someone else. That's what this forum is for so feel free to start your own topic anytime and someone will assist you with your issues specifically.
