As per request, here is my post as directed by step #9.

I am running 64bit so there is no GMER scan/log.

Here is the DDS logs

My previous thread containing some more details and logs of some other scans I have already run is located here: http://www.bleepingcomputer.com/forums/topic470333.html.

Greetings and Welcome to The Forums!!

My name is Gringo and I'll be glad to help you with your computer problems.

I have put together somethings for you to keep in mind while I am helping you to make things go easier and faster for both of us

  • Please do not run any tools unless instructed to do so.
    • We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability.
  • Please do not attach logs or use code boxes, just copy and paste the text.
    • Due to the high volume of logs we receive it helps to receive everything in the same format, and code boxes make the logs very difficult to read. Also, attachments require us to download and open the reports when it is easier to just read the reports in your post.
  • Please read every post completely before doing anything.
    • Pay special attention to the NOTE: lines, these entries identify an individual issue or important step in the cleanup process.
  • Please provide feedback about your experience as we go.
    • A short statement describing how the computer is working helps us understand where to go next, for example: I am still getting redirected, the computer is running normally, etc. Please do not describe the computer as "the same", this requires the extra step of looking back at your previous post.
NOTE: At the top of your post, click on the Watch Topic Button, select Immediate Notification, and click on Proceed. This will send you an e-mail as soon as I reply to your topic, allowing us to resolve the issue faster.

NOTE: Backup any files that cannot be replaced. Removing malware can be unpredictable and this step can save a lot of hartaches if things don't go as planed. You can put them on a CD/DVD, external drive or a pen drive, anywhere except on the computer.

NOTE: It is good practice to copy and paste the instructions into notepad and print them in case it is necessary for you to go offline during the cleanup process. To open notepad, navigate to Start Menu > All Programs > Accessories > Notepad. Please remember to copy the entire post so you do not miss any instructions.

Security Check

  • 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.



Run Combofix:

You may be asked to install or update the Recovery Console (Win XP Only) if this happens please allow it to do so (you will need to be connected to the internet for this)

Before you run Combofix I will need you to turn off any security software you have running, If you do not know how to do this you can find out >here< or >here<

Combofix may need to reboot your computer more than once to do its job this is normal.

You can download Combofix from one of these links.
Link 1
Link 2
Link 3
1. Close any open browsers or any other programs that are open.
2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Double click on combofix.exe & follow the prompts.
When finished, it will produce a report for you.

Note 1: Do not mouseclick combofix's window while it's running. That may cause it to stall

Note 2: If you recieve an error "Illegal operation attempted on a registery key that has been marked for deletion." Please restart the computer

"information and logs"

  • In your next post I need the following
  • Log from Combofix
  • let me know of any problems you may have had
  • How is the computer doing now?

Thank you for the reply. I will begin working on your first set of instructions in about 12 hours or so (I will often make posts from my phone when I am away from my computer).

As of now, the computer is performing normally. Internet browsers run normally, programs run normally (with the exception of MSE and windows firewall of course), etc. I have been running it in safe-mode for the past couple of days in order to prevent further infection or at least slow it down. When I last ran it normally, everything was still running fine. I was only able to catch it through its interaction with MSE. Seeing as MSE was no longer working correctly after the initial scan, I uninstalled it and am currently without firewall and anti-virus.

Also, is it okay to put code logs in spoiler blocks? The code is lengthy and it makes finding instructions in these threads a bit difficult sometimes. If not, thats okay.

Sorry, I fell asleep waiting for the aswMBR scan to finish, I added the log in my previous post. And the TDSSkiller log is up in there now, too, I forgot to post that the first time around. I had to run another scan to get the report again. Is that okay?

Greetings

At this time I would like you to run this script for me and it is a good time to check out the computer to see if there is anything else that needs to be addressed.

:Run CFScript:

Open Notepad and copy/paste the text in the box into the window:

ClearJavaCache::

Save it to your desktop as CFScript.txt

Refering to the picture above, drag CFScript.txt into ComboFix.exe
Posted Image
This will let ComboFix run again.
Restart if you have to.
Save the produced logfile to your desktop.

Note: Do not mouseclick combofix's window whilst it's running. That may cause it to stall

Note 2: If you recieve an error "Illegal operation attempted on a registery key that has been marked for deletion." Please restart the computer

"information and logs"

  • In your next post I need the following

  • report from Combofix
  • let me know of any problems you may have had
  • How is the computer doing now after running the script?

CF is running now. Will edit this post with the log when it's done.

What issues should I be looking to fix? As I mentioned earlier, it runs pretty normally with the exception of windows security essentials and windows firewall not working correctly. Also, it's still in safe mode, so I can't really tell overall how well it's doing until I begin to run it normally again. When would you recommend I switch back to a normal boot?

Edit: scan has finished. Log is in spoiler box at the bottom. Computer appears to be running the same. Should I check and run MSE or something?

Odd that MSE isn't on that list, despite it being listed under the start button.

Hello

:P2P Warning!:

IMPORTANT I notice there are signs of one or more P2P (Person to Person) File Sharing Programs on your computer.

Please note that as long as you are using any form of Peer-to-Peer networking and downloading files from non-documented sources, you can expect infestations of malware to occur
Once upon a time, P2P file sharing was fairly safe. That is no longer true. P2P programs form a direct conduit on to your computer, their security measures are easily circumvented and malware writers are increasingly exploiting them to spread their wares on to your computer. Further to that, if your P2P program is not configured correctly, your computer may be sharing more files than you realise. There have been cases where people's passwords, address books and other personal, private, and financial details have been exposed to a file sharing network by a badly configured program.

Please read these short reports on the dangers of peer-2-peer programs and file sharing.

FBI Cyber Education Letter
File sharing infects 500,000 computers
USAToday
infoworld


These logs are looking allot better. But we still have some work to do.

Please print out these instructions, or copy them to a Notepad file. It will make it easier for you to follow the instructions and complete all of the necessary steps..

uninstall some programs

NOTE** Because of the cleanup process some of the programs I have listed may not be in add/remove anymore this is fine just move to the next item on the list.

You can remove these programs using add/remove or you can use the free uninstaller from Revo (Revo does allot better of a job)

Programs to remove

µTorrent
Adobe Reader 9.1.3
Java™ 6 Update 31
Java™ 6 Update 7
[/list]


  • Please download and install Revo Uninstaller Free
  • Double click Revo Uninstaller to run it.
  • From the list of programs double click on The Program to remove
  • When prompted if you want to uninstall click Yes.
  • Be sure the Moderate option is selected then click Next.
  • The program will run, If prompted again click Yes
  • when the built-in uninstaller is finished click on Next.
  • Once the program has searched for leftovers click Next.
  • Check/tick the bolded items only on the list then click Delete
  • when prompted click on Yes and then on next.
  • put a check on any folders that are found and select delete
  • when prompted select yes then on next
  • Once done click Finish.
.

Update Adobe Reader

Recently there have been vulnerabilities detected in older versions of Adobe Reader. It is strongly suggested that you update to the current version.

You can download it from http://www.adobe.com/products/acrobat/readstep2.html
After installing the latest Adobe Reader, uninstall all previous versions.
If you already have Adobe Photoshop® Album Starter Edition installed or do not wish to have it installed UNcheck the box which says Also Download Adobe Photoshop® Album Starter Edition.

If you don't like Adobe Reader (53 MB), you can download Foxit PDF Reader(7 MB) from here. It's a much smaller file to download and uses a lot less resources than Adobe Reader.

Note: When installing FoxitReader, be careful not to install anything to do with AskBar.
[/list]

Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts.
Click OK to either and let MBAM proceed with the disinfection process.
If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

Working on those instructions right now. Will update when I'm done.

As for the computer, I booted back in normal mode in order to uninstall adobe reader. After it boots, when I log in the screen stays blank for a couple of minutes until everything loads where as when I used to log in it loaded the desktop and taskbar immediately while everything else was still loading.

Secondly, MSE still won't manually update due to connection errors. It says it's updated as of now, but when I manually update definitions it fails due to some connection error.
