Running into a strange issue that seems to orient to a family of infections that seem to behave like the win32 shutdowner trojan.

 

I thought I was maybe having a hardware issue (and it still might be that but I had run Sea Tools from a suggestion the hardware forum and the drive passed). I'm running Windows Vista on a Dell XPS 410 desktop. I usually leave the computer alone and it goes into sleep mode and then by moving the mouse, I activate the screen. I came back two weeks ago and the system was off, so I had started it and the fan started accelerating and the screen wouldn't come on. I cold booted it and it didn't accelerate and the system booted up.  I then noticed that intermittently, I would be working on the computer and it would suddenly either crash, reboot or set up a blue screen with an error message that moved past too fast to read but I did see something about a fatal error.  Sometimes, I would be working and the system wouldn't crash but Firefox would.

 

I noticed that MacAffee had quarantined an infection and my problems had happened about that time. I ran a thorough scan afterwards and no infections showed up. Today, i had noticed that MacAffee updates were stuck at 68% and the little loading icon kept turning but nothing else had happened so I had called MacAffee and they had fixed that problem.

 

However, Firefox just crashed again. I then looked online for a possible cause and the win32shutdowner trojan was blamed for shutting down systems or causing the fan to accelerate because the BIOS wasn't engaged first. Now I had asked Macaffee about that and was surprised to learn that they don't have that trojan in their database.

I'm reading that that trojan is a nasty piece of work because it hides and that you have to remove registry files to eliminate it. I'm not saying I am infected with it but if the Sea Tools, passed my hard drive, then I thought that maybe my registry was corrected or I have an infection in my system that MacAffee doesn't recognize.

 

So I'm not sure if it or something in it's family has invaded my system because MacAffee doesn't have it in their database.

 

One other thing; I did restore my system to a restore point a month before all this nonsense had happened but the problem persists.

I'm thinking it is more likely corrupt files rather than malware. But use the programs below to find and remove adware and malware.

Best to not use sleep mode or hibernate until the problem is resolved.

 

First, check that you are using Firefox 45 +. Check Firefox's Add-ons for updates...especially Adobe Flash plugin.

 

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars....especially Google.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

CCleaner - PC Optimization and Cleaning - Free Download

 

Download Malwarebytes' Anti-Malware from Here

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).

  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • When MBAM is finished scanning it will display a screen that displays any malware that it has detected.
  • Click the Remove Selected button.
  • MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.

POST THE LOG FOR  REVIEW.

 

Download AdwCleaner by Xplode onto your desktop.

  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Scan button.

  • download Junkware Removal Tool to your desktop.
  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message
  • Hold down Control and click on this link to open ESET OnlineScan in a new window.

  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
