Hello. Let me start off by saying I am clueless when it comes to viruses and computer issues. My husband got on my laptop and downloaded a program and the next thing I know my computer is crazy. I click on a link and it sends me to some spam site. I tried using Norton 360 to virus scan and check my computer but it never will start up the scan. It sets there forever doing nothing. I am at a total loss with this and have no idea what to do to fix it. I would graciously and very thankfully appreciate any help in getting my computer back to speed. I am getting ready to start my final year of RN school and have to have this resolved soon in order to do homework. I appreciate any and all advice immensely!

My computer is still having issues. I appreciate you trying to help me. One issue is that when I click on a link it takes me to some spam site. I cannot get norton, symantec, or most antiviruses to scan at all to try to remove this thing. I just ran a fresh scan this morning as requested and am attaching both logs. Thank you for helping me. I appreciate it immensely!

Hi jessee,

There isn't anything obvious in the logs so we need to run a couple of scans to check out what might be there.

Firstly, though...

Please download Posted Image Malwarebytes Anti-Malware and save it to your desktop.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application or, if you are using Vista, right-click and select Run As Administrator 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.
  • On the Scanner tab:
    • Make sure the "Perform Full 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, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

If this does not run then please post back without doing the other scans below.


If it has run and you have the log then please now use the next tool.

We Need to check for Rootkits with RootRepeal
  • Download RootRepeal from the following location and save it to your desktop:
  • Extract RootRepeal.exe from the zip archive.
  • Open Posted Image on your desktop.
  • Click the Posted Image tab.
  • Click the Posted Image button.
  • Check all six boxes: Posted Image
  • Push Ok
  • Check the box for your main system drive (Usually C:), and press Ok.
  • Allow RootRepeal to run a scan of your system. This may take some time.
  • Once the scan completes, push the Posted Image button. Save the log to your desktop, using a distinctive name, such as RootRepeal.txt. Include this report in your next reply, please.
Then we need to take a better look at the PC

We need to create an OTL Report
  • Please download OTL By OldTimer
  • Save it to your desktop.
  • Double click on the Posted Image icon on your desktop.
  • Click the "Scan All Users" checkbox.
  • Push the Posted Image button.
  • Two reports will open, copy and paste them in a reply here:[list]
    OTListIt.txt <-- Will be opened
    Extra.txt <-- Will be minimized
Thanks :thumbup2:

The MBAM report was very enlightening.

There was some major malware in there and we need to make sure that it has gone.

Please download ComboFix from one of these locations:* IMPORTANT !!! Save ComboFix.exe to your Desktop but rename it Combo-Fix.exe
  • 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 Combo-Fix.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.

Posted Image


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

Posted Image


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.

Thanks :thumbup2:

Thanks for the log. It shows that we need to run Combofix again but this time we need to add a script to the program.

First though

The log shows that you have been using so called peer-to-peer or file-sharing programmes (in your case uTorrent and Limewire). These programmes allow to share files between users as the name(s) suggest. In today's world the cyber crime has come a long way and any means is used to infect personal computers to make use of their stored data or machine power for further propagation of their malware files. A popular means is the use of file-sharing tools as a tremendous amount of prospective victims can be reached through it.

It is therefore possible to be infected by downloading manipulated files via peer-to-peer tools and thus suggested to be used with intense care. Some further readings on this subject, along the included links, are as follows: "File-Sharing, otherwise known as Peer To Peer" and "Risks of File-Sharing Technology."

It is also important to note that sharing entertainment files and proprietary software infringes the copyright laws in many countries over the world and you are putting yourself at risk of being indicted through organisations watching over the rights of the authors of such files (i.e. the RIAA for music files, or the MPAA for movie files in the USA) or the authors of the files themselves.

Naturally there are also legal ways to use these services, such as downloading Linux distributions or office suites such as "Open Office."


Back to the fix


1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Open notepad and copy/paste the text in the quotebox below into it:

Folder::
c:\programdata\dyrupulc
c:\programdata\cxhqggwc


Save this as CFScript.txt, in the same location as ComboFix.exe


Posted Image

Refering to the picture above, drag CFScript into ComboFix.exe

When finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Then we should be able to move on to the next steps.

Hello! We are clicking right along! I hope things are looking better and better w/each scan. I TOTALLY agree with you in regards to the peer to peer sharing. I was out of town doing clinicals for my Registered Nurse training program and got home to a broken laptop. After throwing a temper tantrum and thinking my four children were on my computer I find out it was my husband! I was RANCID ANGRY! He and I do NOT agree about him downloading his music, his videos or anything for that matter. He has crashed FOUR of my computers due to this and had to reformat them. Aside from lock him off of them (which trust me, the thought is very near my mind) I can't stop it. I do have my computer passworded but my daughter gave him the code so he could use my cd/dvd burner (only my laptop has one). Now the password is changed and no one knows it. I can assure you this computer is vital to me and I use it strictly for homework only. Anything that has peer to peer connected to it he has done or any file on here that I'm unaware of he has installed. If you can let me know what you see besides the two programs mentioned, I will delete them off the computer and uninstall it all. I do not want anything that could harm my computer on here. I use this for college work and I do facebook and myspace at times too.

Once this computer is clean, I can assure you, you will not see my screen name here again! LOL!

Okay, Jessee we'll remove the P2P folders and files and do a quick clean-up later but first we must let an online scanner remove any infected files - which the P2P programs may have brought in.

I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Push the Start button.
  • 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, push Posted Image
  • Push Posted Image, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the Posted Image button.
  • Push Posted Image
After that we can start the clean-up :thumbup2:

Ok. This scan gave me two options ... uninstall this program and finish. It didn't allow me to print or save any type of report. It also stated that the virus scan found no threats and it did scan over 400,000 files.

That's great news because it means that there are no threats left.

Just before we give the final instructions let's remove the P2P stuff for you.

Backup Your Registry with ERUNT
  • Please use the following link and scroll down to ERUNT and download it.
    http://aumha.org/freeware/freeware.php
  • For version with the Installer:
    Use the setup program to install ERUNT on your computer
  • For the zipped version:
    Unzip all the files into a folder of your choice.
Click Erunt.exe to backup your registry to the folder of your choice.

Note: to restore your registry, go to the folder and start ERDNT.exe

We need to execute an OTM script
  • Please download OTM by OldTimer and save it to your desktop.
  • Double click the Posted Image icon on your desktop.
  • Paste the following code under the Posted Image area. Do not include the word "Code".
    :Files
    c:\users\Jessee Family\AppData\Roaming\BitTorrent
    c:\program files\morpheus
    c:\program files\limewire
    c:\program files\DNA
    c:\program files\bittorrent
    c:\users\jessee family\program files\dna
    :Reg
    [HKLM\~\services\sharedaccess\parameters\firewallpolicy\StandardProfile\AuthorizedApplications\List]
    "c:\\Program Files\\BitTorrent\\bittorrent.exe"=-
  • Push the large Posted Image button.
  • OTM may ask to reboot the machine. Please do so if asked.
  • Copy/Paste the contents under the Posted Image line here in your next reply.
  • If you are unable to copy/paste from this window (as will be the case if the machine was rebooted), open Notepad (Start->All Programs->Accessories->Notepad), click File->Open, in the File Name box enter *.log and press the Enter key, navigate to the C:\_OTM\MovedFiles folder, and open the newest .log file present, and copy/paste the contents of that document back here in your next post.
Post the OTM log.
