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/437256 <<< 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 will not be able to run GMER and you may skip this step.

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!

It said 16/20 found something! Also, when I clicked on the Jotti link, I got an AVG pop-up saying that a threat was detected, and it listed the 'trojan horse hider' again. I temporarily disabled AVG to let this scan run and this is what I got:

Thanks a lot for taking the time to help me out ;)

The file is infected. Please run this tool and will take it from there.

Okay, I ran into two problems. First, I could not disable the Windows Firewall. I attached a picture of the pop-up I got. I made sure to temporarily disable AVG, I closed all open browsers and even disconnected from the internet. When I tried to run combofix I got a warning pop-up saying that Avast Antivirus and Avast AntiSpyware were "active" real time scanners, BUT I never installed Avast! I also made sure to check my "Programs and features" to go ahead and uninstall the software, but its not on there (because I never downloaded it in the first place).

What do I do from here? I'm stuck with the ComboFix Warning pop-up, and I don't know whether I should click "Ok" or X out of the box.

Avast must still have some remnant entries in the Registry or the computer.

Run ComboFix and ignore the message.

We will deal with the firewall after.

Ran ComboFix and restarted computer afterwards. I got two weird pop-ups as ComboFix was running, do you want me to post the images? I think they were fake files/apps.

My netbook seems fine for now, but all of this past week the screen would dim randomly, even if I was moving the mouse. Did that have anything to do with the "trojan horse hider" or is it an unrelated problem? I checked my power options and everything so there's not reason for the screen to dim unless its been inactive for more than 3 mins.

I do not know. Time will tell. Keep an eye on it.

Secure your system by updating 3rd party programs.

Your version of Java is outdated and needs to be updated to take advantage of fixes that have eliminated security vulnerabilities.

Check your present version and update as recommended.
https://www.java.com/en/download/installed.jsp

If present remove the old version(s) of Java using the Add/Remove Programs applet.


Java™ 6 Update 27

Get the latest version of the Adobe Reader.
http://get.adobe.com/reader/
Before your download I suggest you unckeck the box on the top right "Include in your download" this is not required. While the installation is in progress you can also deny the installation of any other programs that may be suggested.

When installed remove your old version of the Reader using the Add/Remove Programs applet if present.

If all is well:

Time for some housekeeping

The following will implement some cleanup procedures as well as reset System Restore points:

Click Start > Run and copy/paste the following bold text into the Run box and click OK:

ComboFix /Uninstall

Delete the other tools we used.
