trojan win64/sinref.W infection. Help please

Welcome to Major Geeks!

Since you cannot do this (which would be the easiest way to get started and bypass the 1 minute shutdown), you will have to try to complete as much of the below as possible. Even if you have to do it in safe boot mode.


Please follow the instructions in the below link:

READ & RUN ME FIRST. Malware Removal Guide

 

Okay, now that you go FRST to run I can see the form or ZeroAccess infection that you have and we need to replace an infected system file. In order to do this, I need to find a backup copy on your PC. I will need you to run the below to help me find this backup. Once we have this info, we can create a fix.

Boot to System Recovery Options and run FRST again.
Type the below bolded text in the edit box after "Search:".

services.exe

Then click the Search button.

It will make a log (Search.txt) on the flash drive. Please attach this log to your next reply. (See How to attach)

 

You're welcome.


Download this >> View attachment fixlist.txt



Save fixlist.txt to your flash drive.

• You should now have both fixlist.txt and FRST64.exe on your flash drive.

Now reboot back into the System Recovery Options as you did previously.
Run FRST64 and press the Fix button just once and wait.
The tool will make a log on the flashdrive (Fixlog.txt).
Please attach this to your next message. (See how to attach)

Now boot into normal Windows can continue with the below.


Now from normal Windows, run MGtools per the below instructions and attach the C:\MGlogs.zip file.

Using MGtools

Make sure you tell me how things are working now!

 

Just save it anywhere, and then transfer iit to C:\ yourself. MGTools is an information collector. Helps us target all traces of malware.

 

Having admin priviledges has nothing to do with where you save it. It just needs as administrator as stated if running Windows Vista or Win 7. You can save it anywhere on the drive the Windows loads from but we prefer either the root folder ( C:\MGtools.exe ) or the Desktop folder so that our final cleanup steps can find it and remove it when we are ready.

Once you attach this log we can continue.

Is your PC still working OK?

 

I guess you and your son did not notice that Windows FIrewall and a few other services were broken.

Download the below file and save it to your Desktop

BITS.reg

Then right click on it and select Merge. If prompted, allow it to be added to your registry.

Be patient while doing the below. The fixes can take quite awhile to run. Especially the permissions repairs. It may be best to kick it off and goto bed or do something else. It is better not to run anything while the repairs are going on.

Download Windows Repair by Tweaking.com and unzip the contents into a newly created folder on your desktop.

• Now run Repair_Windows.exe by double clicking on it ( if you are running Vista or Win 7, use right click and select Run As Administrator)
• Now select the Start Repairs tab.
• The click the Start button.
• Create a System Restore point if prompted.
• On the next screen, click the Unselect All button to first deselect all repairs.
• Now select the following repair options:
  • Reset Registry Permissions
  • Reset File Permissions
  • Register System Files
  • Repair WMI
  • Repair Windows Firewall
  • Remove Policies Set By Infections
  • Repair Winsock & DNS Cache
  • Repair Proxy Settings
  • Repair Windows Updates
  • Set Windows Services To Default Startup
• Now on the lower right side check the box to Restart/Shutdown System When Finished
• Then make sure the Restart System radio button is enabled.
• Shutdown any other programs that you are running now before continuing.
• Now click the Start button.
• Be patient while the tool repairs the selected items.
• It should reboot automatically when finished.

Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator).

Then attach the below logs:

• C:\MGlogs.zip

Make sure you tell me how things are working now!

 

You're welcome.

That looks much better. All the services I noticed that were broken are now fix. See how things work for a day or so and then if all is good, complete the below final instructions.



If you are not having any other malware problems, it is time to do our final steps:

1. We recommend you keep Malwarebytes Anti-Malware for scanning/removal of malware. You can uninstall RogueKiller and HitManPro.
3. Go back to step 6 oof the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
6. If running Vista or Win 7, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
7. Go to add/remove programs and uninstall HijackThis.
8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
   related to MGtools and some other items from our cleaning procedures.
9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
   • Refer to the cleaning procedures pointed to by step 7 of the READ ME
     for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
   • Then reboot and Enable System Restore to create a new clean Restore Point.
10. After doing the above, you should work thru the below link:
