My wife's computer has been acting strangely, settings are changing, yahoo email hacked, wallpaper changing and her browser has been acting strange on occasion too. She called a guy about the yahoo account and he scanned her computer and said there was a possible network infection which I suppose means all the computers on our network and possibly our router could be infected. He said there was a trojan of some kind, possibly with 21 as part of the name. I will also be posting her logs under the Jameson.

Thanks for the help

Hello and welcome to Bleeping Computer!

I am HelpBot: an automated program designed to help the Bleeping Computer Staff better assist you! This message contains very important information, so please read through all of it before doing anything.

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. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

To help Bleeping Computer better assist you please perform the following steps:

***************************************************

Posted Image In order to continue receiving help at BleepingComputer.com, YOU MUST tell me if you still need help or if your issue has already been resolved on your own or through another resource! To tell me this, please click on the following link and follow the instructions there.

CLICK THIS LINK >>> http://www.bleepingcomputer.com/logreply/459208 <<< CLICK THIS LINK



If you no longer need help, then all you needed to do was the previous instructions of telling me so. You can skip the rest of this post. If you do need help please continue with Step 2 below.

***************************************************

Posted Image If you still need help, I would like you to post a Reply to this topic (click the "Add Reply" button in the lower right hand of this page). In that reply, please include the following information:

  • 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.
  • Please tell us if you have your original Windows CD/DVD available.
  • Upon completing the above steps and posting a reply, another staff member will review your topic and do their best to resolve your issues.

Thank you for your patience, and again sorry for the delay.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • 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.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows, you should not bother creating a GMER log.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!

Thanks for your help

This topic has been re-opened at the request of the person who originally posted.

Third party programs if not up to date can be the cause infiltration of an infection.

Please run this security check for my review.

Download Security Check by screen317 from 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.

Note: If after running ComboFix you get this error message "Illegal operation attempted on a registry key that has been marked for deletion." when attempting to run a program all you need to do is restart the computer to reset the registry.

Please post the logs for my review.

The ComboFix log is clean.

Check your present version and update as recommended.
