Malware - possible rootkit?


Recommended Posts

My computer has acted suspiciously for 2-3 months; I've run various cleanup software, works better, then goes back to being slow, not opening programs, locking up, etc. Recently it's locking up constantly. Spybot shows a freeze.com file, that it says it will delete upon restart; but it hasn't(ran scan twice.) I had used your software back in August...seemed to help, but. I consulted your support forum directions and have tried to run a Smart Scan 3x; computer always freezes. So I ran a Quick Scan and that did complete. I am attaching the log from the Quick Scan(as well as the old log from several months ago) and the OTL logs. Please help...or tell me where else to look for help!

Good job!

Download Combofix from the link below, and save it to your desktop.

Link

**Note: It is important that it is saved directly to your desktop**

If you get a message saying "Illegal operation attempted on a registry key that has been marked for deletion", please restart your computer.

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

IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

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

Right-Click and Run as Administrator on ComboFix.exe & follow the prompts.


  • When finished, it will produce a report for you.
  • Please post the C:\ComboFix.txt for further review.

Jeff:

I'm on my third try, but can't get ComboFix to run. It was saved directly to my desktop, and I ran it as an administrator. It opens all the files and then a blue screen, Administrator at the top left, says;

"Please wait.

ComboFix is preparing to run.

Attempting to create a new System Restore point."

It never progresses past that point(I've left it for >an hour). I've turned off security essentials, windows firewall, spybot, malwarebytes, and a couple of other random things.

Any ideas? another suggested program?

Thanks,

Suzie

Hi,

Download Combofix from any of the links below but rename it to Vageta.com before saving it to your desktop.

Link 1

Link 2

==================================

Right-click and Run as Administrator on the renamed ComboFix.exe & follow the prompts.

  • When finished, it will produce a report for you.
  • Please post the C:\ComboFix.txt so we can continue cleaning the system.

I get the same result. Vageta/combofix extracts the files and backs up registry; then a new screen pops up with the message "attempting to create a new system restore point". Nothing happens after that; and eventually the computer locks up and a I have to do a cold boot to restart. After that happened, I deleted both ComboFix and Vageta from my desktop; downloaded the file again(from the first link, second one doesn't work for me), renamed to vageta and tried again with the same result.

Next thought?

Thanks,

Suzie

Jeff:

It seems that my computer is actually working!! The Windows update was installed, it is responding to commands without dragging...it looks like it's fixed!

I'm attaching the logs; the first from the fix and the second from the scan.

I have been using Microsoft Security Essentials and previously also used Windows Defender(have Vista on this machine); although the Defender was disabled by the virus/rootkit/whatever and I was unable to reinstall it. The problem, I believe, originated when I used an unsecured network in an airport while traveling...

Any suggestions/preferences for anti-virus/malware programs?

Thanks for your help and patience,

Suzie

One more issue...I can't turn on Windows Defender. Tried to access via Control panel; message box says it's turned off and it won't turn on when I push Turn on. I looked at program files/Window Defender to start the exe. file; same message box comes up, that its' turned off.

I go to the defender website to download and it aborts the download, saying that it came with Vista and I should access it via program files. This is the first problem I initially had back in late July...

Thanks,

Suzie

Good!

Stick with me while we check for anything else hiding. I will go over your other questions before we finish up. :)

I see that your Java software is out of date. Please go to Start >> Control Panel >> Programs and Features >> uninstall all versions of Java.

Now download and install the newest version from here >> http://java.com/en/download/index.jsp

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

Clear Java Cache

See this page for instructions on how to clear java's cache.

Go into the Control Panel and double-click the Java Icon. (looks like a coffee cup)

  • Under Temporary Internet Files, click the Delete Files button.
  • There are three options in the window to clear the cache - Leave ALL 3 Checked

    • Downloaded Applets
      Downloaded Applications
      Other Files

    [*]Click OK on Delete Temporary Files Window

    Note: This deletes ALL the Downloaded Applications and Applets from the CACHE.

    [*]Click OK to leave the Java Control Panel.

----------

Malwarebytes

Please open Malwarebytes, update it and then run a Quick Scan. Save the log that is created for your next reply.

----------

ESET Online Scanner

Go here to run an online scannner from ESET. Windows Vista/Windows 7 users will need to right click on their Internet Explorer shortcut, and select Run as Administrator

  • Note: For browsers other than Internet Explorer, you will be prompted to download and install esetsmartinstaller_enu.exe. Click on the link and save the file to a convenient location. Double click on it to install and a new window will open. Follow the prompts.
  • Turn off the real time scanner of any existing antivirus program while performing the online scan
  • Tick the box next to YES, I accept the Terms of Use.
  • Click Start
  • When asked, allow the activex control to install
  • Click Start
  • Make sure that the option Remove found threats is unticked and the Scan Archives option is ticked.
  • Click on Advanced Settings, ensure the options Scan for potentially unwanted applications, Scan for potentially unsafe applications, and Enable Anti-Stealth Technology are ticked.
  • Click Scan
  • Wait for the scan to finish
  • When the scan is done, if it shows a screen that says "Threats found!", then click "List of found threats", and then click "Export to text file..."
  • Save that text file on your desktop. Copy and paste the contents of that log as a reply to this topic.
  • Close the ESET online scan, and let me know how things are now.

----------

Please download Farbar Service Scanner and run it on the computer with the issue.

  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center
    • Windows Update
    • Windows Defender

    [*]Press "Scan".

    [*]It will create a log (FSS.txt) in the same directory the tool is run.

    [*]Please copy and paste the log to your reply.

Ok, I finally got everything completed. Java is installed, cache cleared(should I do that every time I download their updates?), ESET run(wouldn't complete in IE, so I ran it in Chrome); and FSS. Logs are attached.

Amazing how many trojans are on the machine! Guess it explains why the machine hangs up, slows down and freezes

up so much. It appears to be running better, but I'd have to use it for a day or so and see if those issues have gone away.

Thanks,

Suzie

Press your Windows key + R and this will open the Run box.

In the Run text bar type services.msc and this will open the Services on your system.

Find Windows Defender and scroll over to Startup Type and double click on that.

In the General tab go to Startup type dropdown and change it to Automatic

Press OK

Reboot your system and then see if Windows Defender is fixed up.

That is what I thought....Microsoft Security Essentials now turns off Windows Defender by default because it is integrated into the antivirus program itself. So there is not actually a problem.

Providing there are no other malware related problems...

IT APPEARS THAT YOUR LOGS ARE NOW CLEAN SO LETS DO A COUPLE OF THINGS TO WRAP THIS UP!!

This infection appears to have been cleaned, but I can not give you any absolute guarantees. As a precaution, I would go ahead and change all of your passwords as this is especially important after an infection.

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

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

Press the Windows key + R and this will open the Run box. Copy/paste the following text into the Run box as shown and click OK.

Combofix /Uninstall

(Note: There is a space between the ..X and the /U that needs to be there.)

CF.jpg

----------

Clean up with OTL:

  • Right-click and Run as Administrator OTL.exe to start the program.
  • Close all other programs apart from OTL as this step will require a reboot
  • On the OTL main screen, press the CLEANUP button
  • Say Yes to the prompt and then allow the program to reboot your computer.

----------

Any of the logs that you created for use in the forums or remaining tools that have not yet been removed can be deleted so they aren't cluttering up your desktop.

If you didn't already have it I would keep Malwarebytes AntiMalware though.

Here are some tips to reduce the potential for spyware infection in the future:

1. Internet Explorer. Even if you don't use it as your main browser it should be kept up-to-date because that is the browser Windows uses for updates.

Make your Internet Explorer more secure - This can be done by following these simple instructions:

  • From within Internet Explorer click on the Tools menu and then click on Options.
  • Click once on the Security tab
  • Click once on the Internet icon so it becomes highlighted.
  • Click once on the Custom Level button.
  • Change the Download signed ActiveX controls to Prompt
  • Change the Download unsigned ActiveX controls to Disable
  • Change the Initialize and script ActiveX controls not marked as safe to Disable
  • Change the Installation of desktop items to Prompt
  • Change the Launching programs and files in an IFRAME to Prompt
  • Change the Navigate sub-frames across different domains to Prompt
  • When all these settings have been made, click on the OK button.
  • If it prompts you as to whether or not you want to save the settings, press the Yes button.
  • Next press the Apply button and then the OK to exit the Internet Properties page.

2. FireFox. If you use Firefox, I recommend installing the following add-ons to help make your Firefox browser more secure:

NoScript

AdBlock Plus

3. Enable Protected Mode in Internet Explorer. This helps Windows Vista users stay more protected from attack by running Internet Explorer with restricted privileges as well as reducing the ability to write, alter or destroy data on your system or install malicious code. To make sure this is running follow these steps:

  • Open Internet Explorer
  • Click on Tools > Internet Options
  • Press Security tab
  • Select Internet zone then place check next to Enable Protected Mode if not already done
  • Do the same for Local Intranet, Trusted Sites and Restricted Sites and then press Apply
  • Restart Internet Explorer and in the bottom right corner of your screen you will see Protected Mode: On showing you it is enabled.

4. Use and update an anti-virus software - I can not overemphasize the need for you to use and update your anti-virus application on a regular basis. With the ever increasing number of new variants of malware arriving on the scene daily, you become very susceptible to an attack without updated protection.

5. Firewall

Using a third-party firewall will allow you to give/deny access for applications that want to go online. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a firewall in its default configuration can lower your risk greatly. I would personally only recommend using one of the following two below:

Online Armor Free

Agnitum Outpost Firewall Free

6. Make sure you keep your Windows OS current. Windows XP users can visit Windows update regularly to download and install any critical updates and service packs. Windows Vista/7 users can open the Start menu > All Programs > Windows Update > Check for Updates (in left hand task pane) to update these systems. Without these you are leaving the back door open.

7. WOT (Web of Trust) As "Googling" is such an integral part of internet life, this free browser add on warns you about risky websites that try to scam visitors, deliver malware or send spam. It is especially helpful when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites. WOT has an add-on available for Firefox, Internet Explorer as well as Google Chrome.

8.Finally, I strongly recommend that you read How to Prevent Malware found here and also PC Safety and Security - What Do I Need?.

Please reply to this thread once more if you are satisfied so that we can mark the problem as resolved.

I can't access the combofix uninstall page on either chrome or IE...I'll try later today.
There is no page....you just have to open the Run box and put Combofix /uninstall inside of it and press Enter. It should uninstall it on its own....it will look like ComboFix is running again but it is actually uninstalling itself.

Jeff:

Sorry, brain challenged. I did remove combofix and all the log files; cleaned up with OTL, made the security changes you recommended. I've kept malwarebytes (I keep it on the desktop to run when something weird pops up).

I downloaded Online Armor's firewall, but can't get it to install. My laptop freezes up on the last line of the security check, twice.

I also can't get MS Security Essentials to run a full scan, same thing, it freezes up. In between attempts, I've checked my power settings; display and system are set to be always on when hooked up to power.

Also, over the last few days, the machine freezes up over time(after 1-2 hours?) and display would be frozen, mouse wouldn't work; pushing esc/enter/power button has no effect. So something is causing the machine to lock up. Overnight, the display would grey; as if it had gone to sleep; but it wouldn't respond and come back on when I pushed the power button. I can't launch Task Manager to see what's going on, either.

I can launch IE or Chrome, use the internet, or word/excel; and those seem to work ok if I'm not running many programs. But the issue of the machine freezing up has not gone away..

Any other ideas? Thanks for your help thus far,

Suzie

First open an elevated command prompt > Click Start and type cmd in Start Search.

When cmd.exe populates above, right click it and select Run as Administrator to open an elevated command prompt.

Copy the contents of the code box > right click in the command window and select paste >> Press Enter (do one line at a time if there are more than one)

chkdsk /f

Follow any prompts and once complete let me know how your system is running.

I must be an idiot. I pull up the cmd.exe box, but there is no option to run it as an administrator. I've right clicked all over the screen and that option never materializes...and yes, if I put the chkdsk command in without, it tells me I need an elevated command prompt. What am I doing wrong?

Got to tell you, this process is getting old....

Thanks, Jeff!

Hi,

There was a very serious infection on your system that probably created some damage that we are dealing with now unfortunately. Sometimes the damage may be extensive. I appreciate your patience while we have been working on this... :)

Download Windows Repair (all in one) from this site

Install and then run the program.

On the Start Repairs tab, select Advanced Mode and click Start

Capture1.gif

Select the items Checked in the screen shot below (remove the checks from the rest ) and check Restart System When Finished.

I ran the Tweaking Windows.com; completed and rebooted. I then downloaded/installed 14 updates from Windows Update, no problem. I also ran other programs at the same time, leaving that in background, and it was fine; a little slower, but nothing unexpected. However, I still can't get MS Security Essentials to complete a scan(it downloads updates and does run Quick Scan no problem, but not a full scan.) I'm considering uninstalling and reinstalling a new copy; or maybe just dumping it and downloading free version of Avast and using Windows Defender again.

Suggestions? Good, bad, whatever; I'm open to all.

Thanks for your patience,

Suzie

Jeff:

I did uninstall MS Security Essentials and download Avast; AVAST first run took hours, but it did complete a full scan(and in the process, Windows Defender popped back up ready to go.) Couple of things that showed up and/or I don't know what to do about.

First, I've deleted everything I downloaded during this clean-up process with the exception of Malwarebytes Rootkit, Malwarebytes(free trial which is going to expire in 4 days anyway); and Emsisoft. I deleted TDSSKiller, but there is still a TDSSKiller Quarantine file; and all kinds of bad stuff is in there. It popped up over and over in the Avast scan, so I told Avast to ignore it. Can I safely delete that file(not a program so it doesn't show up in Control Panel) and then permanently delete from my Recycle Bin?

Also, when I look at the list on my C:/ drive (under Computer), Vageta is there...but the icon is a computer(just like the C drive); and when I expand it, it shows C:/, D:/ E:/ and Photo Stream; as if it copied my C:/ drive. Properties show it to be a file...although it looks like a shortcut. Can I delete that?

Outside of that, it appears(cross your fingers!) as if the computer is running normally.

Thanks,

Suzie

I would remove Malwarebytes Rootkit but keep the others. :)

You can delete that safely....no problem.

Vageta is there
You should be able to remove that as well.
