svchost.exe - playing random sound files. Please help!

[capncam]

Hi everyone,

Starting today my computer has suddenly started playing bizarre music and what sounds like clips from movies at random. I found out ending the process "svchost.exe" stops the music, but every time I stop the process, it comes right back. I'm sure I'm infected, and have no idea how to proceed. Can somebody please help?

Thanks.

Hello, and thanks so much for your help. Here are the first two logs you asked for. I ran malwarebytes after my initial post and it seems to have slowed down the onslaught of svchost.exe for the moment, at least.

dds.txt

attach.txt

[capncam]

And here is the roguekiller report. Looks like something called zeroaccess.

RKreport1_S_04302013_02d2009.txt

[MrCharlie]

Please read the following information first.

You're infected with Rootkit.ZeroAccess, a BackDoor Trojan.

BACKDOOR WARNING

------------------------------

One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would advice you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

http://www.dslreports.com/faq/10451

When Should I Format, How Should I Reinstall

http://www.dslreports.com/faq/10063

I will try my best to clean this machine but I can't guarantee that it will be 100% secure afterwards.

Let me know what you decide to do. If you decide to go through with the cleanup, please proceed with the following steps.

-----------------------------------------

Run RogueKiller again and click Scan

When the scan completes > click on the Registry tab

Put a check next to all of these and uncheck the rest: (if found)

[HJ INPROC][ZeroAccess] HKCR\[...]\InprocServer32 : (C:\$Recycle.Bin\S-1-5-21-2214748242-2495860862-1536195380-1000\$eaf17607883368f213aa6c17f8c822a8\n.) [x] -> FOUND

Now click Delete on the right hand column under Options

-------------

Then.............

Download Malwarebytes Anti-Rootkit from HERE

• Unzip the contents to a folder in a convenient location.
  
• Open the folder where the contents were unzipped and run mbar.exe
  
• Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
  
• Click on the Cleanup button to remove any threats and reboot if prompted to do so.
  
• Wait while the system shuts down and the cleanup process is performed.
  
• Perform another scan with Malwarebytes Anti-Rootkit to verify that no threats remain. If they do, then click Cleanup once more and repeat the process.
  
• When done, please post the two logs produced they will be in the MBAR folder..... mbar-log.txt and system-log.txt
  

To attach a log if needed:

Bottom right corner of this page.

New window that comes up.

~~~~~~~~~~~~~~~~~~~~~~~

Note:

If no additional threats were found, verify that your system is now running normally, making sure that the following items are functional:

Internet access

Windows Update

Windows Firewall

If there are additional problems with your system, such as any of those listed above or other system issues, then run the fixdamage tool included with Malwarebytes Anti-Rootkit and reboot. It's located in the Plugins folder which is in the MBAR folder.

Just run fixdamage.exe.

Verify that your system is now functioning normally.

[capncam]

Hello again! I ran both programs. The malwarebyte anti-rootkit tool found a few things the first time, but none after the first cleanup. Here are the logs.

mbar-log-2013-04-30 (20-48-33).txt

mbar-log-2013-04-30 (21-19-42).txt

system-log.txt

[MrCharlie]

OK...Next:

Please download and run ComboFix.

The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

Please visit this webpage for download links, and instructions for running ComboFix

http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.

---------->NOTE<----------

If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

MrC

[capncam]

Thanks again for your continuing help. Here's the combofix report.

ComboFix.txt

[MrCharlie]

Looks Good.....How is it??? MrC

[capncam]

I don't notice anything unusual anymore. Thanks a ton! That was super bizarre when my computer just started reciting the lord's prayer at me, haha.

[MrCharlie]

Good.......Lets check for any adware while you're here:

Please download AdwCleaner from here and save it on your Desktop.

AdwCleaner is a reliable removal tool for Adware, Foistware, toolbars and potentially unwanted programs.

AdwCleaner is a tool that deletes :

· Adwares (software ads)

· PUP/LPI (Potentially Undesirable Program)

· Toolbars

· Hijacker (Hijack of the browser's homepage)

It works with a Search and Deletion methode. It can be easily uninstalled using the "Uninstall" mode.

1. Right-click on adwcleaner.exe and select Run As Administrator (for XP just double click) to launch the application.
   
2. Now click on the Search tab.
   
3. Please post the contents of the log-file created in your next post.

Note: The log can also be located at C:\ >> AdwCleaner[XX].txt >> XX <-- Denotes the number of times the application has been ran, so in this should be something like R1.

Note:

Please look over what was found......especially any folders, we're going to permanently delete it all in the next step....if there's something you may want to keep...please let me know and I'll explain to why it shouldn't be on your system.

If you see AVG Secure Search being targeted for deletion, Here's Why and Here. You can always Reinstall it.

Please note that Antivir Webguard uses ASK Toolbar as part of its web security. If you remove ASK by using Adwcleaner, Antivir Webguard will no longer work properly. Therefore, if you use this program please use the instructions below to access the options screen where you should enable /DisableAskDetections before using AdwCleaner.

You can click on the question mark (?) in the upper left corner of the program and then click on Options. You will then be presented with a dialog where you can disable various detections. These options are described below:

/DisableAskDetection - This option disables Ask Toolbar detection.

If you used DeFogger to disable your CD Emulation drivers, please re-enable them.

-------------------------------

Please download OTL from one of the links below: (you may already have OTL on the system)
