Black screen after the welcome screen. Am I infected?

[mathun]

Problem encountered:

When I start up windows, right after the welcome screen all I get is a black screen and only the mouse pointer is visible.

So I restarted the computer like 5 times and the problem still occured, but then after like 7 trys the black screen was gone. What is causing this? Could it be a potential Virus that is undetected?

Additional Information:

Couple days ago I scanned with MalwareBytes Anti-Malware PRO v.1.70.0.1100 and eliminated "Stolen.Data" infection. (It Was a .png file, basically a screen capture of my whole screen), but I noticed that there were several other screen captures, so I immediately deleted them all. The last known downloaded item was MinGW and eclipse c/c++, and this was yesterday.

Not much showing...lets run some scans.....

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.

mbar-log-2012-12-31 (14-21-05).txt

[MrCharlie]

Ok............

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.bleepingc...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

[mathun]

Here's the ComboFix log.

ComboFix.txt

[MrCharlie]

Can you find this file and upload it to VirusTotal for a free scan, let me know the results (just copy back the url)

c:\programdata\Microsoft\Microsoft Antimalware\Definition Updates\{67A57288-3E9A-4CFC-AD5C-452EC8CE0FD0}\MpKsl394d7096.sys

You may have to enable hidden files to see it:

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

Then.........

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

AdwCleaner is a reliable removal tool for adware, toolbar 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.

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.

MrC

[mathun]

Regarding the first part, I can't seem to find it.

[MrCharlie]

Look in the Updates folder, MrC

[mathun]

Nope, nothing matches what is requested. In the Updates folder, I can't only find:

mpasbase.vdm

mpasdlta.vdm

mpavbase.vdm

mpavdlta.vdm

mpengine.dll

[MrCharlie]

OK, continue on.... MrC

[mathun]

Here's the next log.

AdwCleanerR1.txt

[MrCharlie]

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.

Reboot and let me know how it is, MrC

[mathun]

Alright, here's the log

AdwCleanerS1.txt

[MrCharlie]

OK, how's the booting problem now??? any improvement?? MrC

[mathun]

It's seems like everything is solved, system is running faster, and didn't experience any black screens on restarts.

Thank you so much for all the time and effort you put to helping me remove these infections. THANK YOU! YOU'RE THE BEST!

Oh, and is it safe to remove all these files/folders that were created by these application?

[MrCharlie]

Looks like you're missing a service pack, I would check with Windows Update.

Your Java is OK, nothing to do there.

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

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 /

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

[mathun]
