I am experiencing a black screen without mouse after the HP logo at startup of my laptop. As such, I cannot log onto my computer (no login screen). I have no idea if this is a virus, or what.

My OS: Windows 8.1

The Backstory: I clicked a link online that opened a video and created a pop-under. Using my mouse, I first closed the pop-under. I then stopped the video that was playing and closed that browser window. Immediately, my mouse icon disappeared. I figured that something nasty might be happening to my computer so I shut down the computer manually using the power button. Now, when I start my computer I first get the HP boot logo then my screen goes black. After about a minute or so I notice that the depth of darkness in my screen changes, as if my computer is going into sleep or hibernation.

Right now, the only way that I am able to use my computer is to log on in Safe Mode. There is, however, a black screen which shows for about a minute before the password login screen when entering Safe Mode.

NOTE: I noticed a hidden file in my C:\Windows\ directory with a Chinese filename. The filename is 捉湯牗獫䤮䥎

NOTE: My system logs are showing a lot of errors associated with Bonjour Service since my problems began. I did not knowingly install this Bonjour Service and I don't even know what it is for.

What I have done so far: The following is pretty much everything that I have done so far in SAFE MODE hoping to rectify the problem -

ACTION: Ran Automatic Repair [Startup Settings -> Troubleshoot -> Advanced Options -> Automatic Repair]
RESULT: After the diagnosis is ran my computer returns a message that the repair could not be completed.

ACTION: Ran HijackThis
RESULT: Noticed a couple of peculiar items listed in the HijackThis log:
(1) O4 - HKUS\S-1-5-18\..\Run: []  (User 'SYSTEM')
(2) O4 - HKUS\.DEFAULT\..\Run: []  (User 'Default user')

ACTION:    Update Windows Defender Signature Files
ACTION:    Run Windows Defender
RESULT:    No Infections Found

ACTION: Update Spybot S&D Signature Files
ACTION:    Run Spybot S&D
RESULT:    No Infections Found

ACTION: Update Malwarebytes Anti-Malware Signature Files
ACTION:    Run Malwarebytes Anti-Malware
RESULT:    No Infections Found

ACTION: Update TrojanHunter 6.1 Signature Files
ACTION: Run TrojanHunter
RESULT: 2 Infections Detected: (1) Generic.TrojanDownloader.A; (2) LdPinch.1457
ACTION: Cleaned/Delete infected files.

ACTION:    Installed and ran CCleaner Pro (Trial Version)
RESULT: Analyzed and cleaned Internet Explorer, Windows Explorer and System using default settings in CCleaner.

ACTION: Installed and ran AdwCleaner 6.0.1.0
RESULT:    AdwCleaner indicated that it detected 3 infections, then returned two error messages before the scan was complete as

follows:
(1) Titlebar: AdwCleaner - v.6.010 - ToolsLib: AdwCleaner.exe - Application Error; Message: The instruction at 0x77779f03

referenced memory at 0x000000b6. The memory could not be read. Click on OK to terminate the program
(2) Titlebar: AdwCleaner is a free Adware/PUP removal...; Message: A problem caused the program to stop working correctly.

Windows will close the program and notify you if a solution is available.
ACTION: Clicked OK in the first error message; Clicked Close Program in the second error message.
REMARK: After closing the program I ran it again and checked for a log file. No log files had been saved.

ACTION: Installed and ran SUPERAntiSpyware
RESULT: No potentially harmful items detected.

ACTION: Attempted to install Emsisoft AntiMalware 11.0.0.6054
RESULT: Received the following error message - Titlebar: Emsisoft Protection; Message: A major problem prevents application start. Emsisoft Security can't connect to the service application. Please restart your PC and try again or contact support if the problem remains.
REMARK: This is probably because I am attempting to install the software in Safe Mode.

Additional Info

In my original post I mentioned that I attempted to run Automatic Repair from the Advanced Options and that a message was returned stating that the repair could not be completed. I forgot that Automatic Repair had saved a log file, so I just checked that file at C:\Windows\System32\LogFiles\Srt\SrtTrail.txt

According to the log file, all tests performed by Automatic Repair "Completed successfully. Error code = 0x0". The final section of the logfile states "Root cause found: Boot status indicates that the OS booted successfully."

So, I guess that Automatic Repair could not complete the repairs because it didn't detect any problems with the system. Even still, all I get after the HP boot logo is a black screen.

If you haven't tried doing a System Restore using a restore point prior to the date of the first black screen....try doing one.

Thanks buddy215. The date of the first black screen was 29 Aug 2016. I did a System Restore to 22 Aug 2016 but that did not resolve the problem.

Before going to bed last night I attempted to run AdwCleaner again after rebooting my laptop into Safe Mode. This time, the AdwCleaner software did work. I guess AdwCleaner just required a reboot after installation for it to work. I only used it to scan my computer - I did nothing else. The logfile returned by AdwCleaner shows 1 folder, 1 file, and 2 registry entries.

I'm not sure malware is involved or not. Try performing the scans and posting the logs in the Malware Removal Forum by following the directions below.

 

Please follow the instructions in the Malware Removal and Log Section Preparation Guide starting at Step 6.

  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running FRST which will create two logs.

When you have done that, post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs...start the new topic anyway. Explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.

After doing this, please reply back in this thread with a link to the new topic so we can close this one.

 

DO NOT bump your new topic. Wait for a response from one of the Team Members.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.
Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 3 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
