Friend (really) had ransomware (FBI warning, webcam showing her picture). I tried to help and we ran malwarebytes in safe mode, then again in normal boot. The computer is usable, but Malwarebytes shows two infections it can't remove (even after reboot). I have also run SurfRight Hitman Pro which detected nothing.

I've attached the DDS and Attach.txt from DDS.com execution (I could not find DDS.scr). Win 7 did not give me the option to run the .com file as administrator (Win 7) so it was not run as an administrator.

Thank you in advance for any assistance.

Steve

Welcome to the forum.

Please remove any usb or external drives from the computer before you run this scan!

Please download and run RogueKiller to your desktop.

Quit all running programs.

For Windows XP, double-click to start.

For Vista or Windows 7, do a right-click on the program, select Run as Administrator to start, & when prompted Allow to run.

Click Scan to scan the system.

When the scan completes > Close out the program > Don't Fix anything!

Don't run any other options, they're not all bad!!!!!!!

Post back the report which should be located on your desktop.

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)

[sHELL][sUSP PATH] HKCU\[...]\Windows : Load (C:\Users\Micah\LOCALS~1\Temp\msfdrc.cmd) -> FOUND

[sHELL][sUSP PATH] HKUS\S-1-5-21-3717972008-2009066130-3228823747-1000[...]\Windows : Load (C:\Users\Micah\LOCALS~1\Temp\msfdrc.cmd) -> FOUND

Now click Delete on the right hand column under Options

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

Next click on the Files tab and put a check next to these and uncheck the rest. (if found)

[ZeroAccess][FOLDER] U : C:\$recycle.bin\S-1-5-21-3717972008-2009066130-3228823747-1000\$559073a09ae139c17f3af92761201742\U --> FOUND

[ZeroAccess][FOLDER] L : C:\$recycle.bin\S-1-5-21-3717972008-2009066130-3228823747-1000\$559073a09ae139c17f3af92761201742\L --> FOUND

Now click Delete on the right hand column under Options

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

Next.......

Please create a new system restore point before running Malwarebytes Anti-Rootkit if you can.

MBAR tutorial

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.

Verify that your system is now functioning normally.

I am in the process of following the removal instructions. I will forward your forum message to the pc's owner and let her decide how she's wants to proceed in terms of reformatting/reinstalling. I will post the scan results when it completes...

Good...........

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

  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.

Please look over what was found, we're going to 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.

Some adware found....lets clear it out.....

  1. Please re-run AdwCleaner
  2. Click on Delete button.
  3. Confirm each time with OK if asked.
  4. Your computer will be rebooted automatically. A text file will open after the restart. Please post the content of that logfile in your reply.

Note: You can find the logfile at C:\AdwCleaner[sn].txt as well - n is the order number.

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

Lets check your computers security before you go and we have a little cleanup to do also:

Download Security Check by screen317 from HERE or 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.
  • Do Not Attach It!!!

I installed acrobat reader XI and the latest version of java (both 32 and 64 bit) I could find (java 7, update 10)

Hopefully my assumption is correct that this was a good thing to do.....

Look forward to your reply and, again, thanks for all the help.

That was the correct version of Java that you had, I'm not sure why it says it's out of date.

http://www.java.com/...load/manual.jsp

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

A little clean up to do....

Please Uninstall ComboFix: (if you used it)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /

cf2.jpg

Then hit enter.

This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall)

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

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

http://oldtimer.geekstogo.com/OTL.exe

http://oldtimer.geekstogo.com/OTL.com

http://www.itxassoci...T-Tools/OTL.exe

Save it to your desktop.

Run OTL and hit the CleanUp button. (This will cleanup the tools and logs used including itself)

Any other programs or logs you can manually delete.

IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST, MBAR, etc....AdwCleaner > just run the program and click uninstall.

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

Any questions...please post back.

If you think I've helped you, please leave a comment > click on my avatar picture > click Profile Feed.

Take a look at My Preventive Maintenance to avoid being infected again.

Good Luck and Thanks for using the forum, MrC
