Hello, 

 

My laptop had been running fine for the past few days but now it would not start up properly. Screen goes completely blank right after Windows Startup. There will be a log in screen for a few seconds and it goes blank.

 

I was able to start in safe mode without any problems. What I did next was to disable all services through msconfig and I was able to start the laptop normally. 

 

I have no idea how do I know which part of the laptop is infected and also which services is preventing Windows to start normally. 

 

I am using HP Pavilion dm3 and running on Windows 7.

Welcome aboard p22002758.gif

 

We don't know if this is caused by some infection yet.

 

p22002970.gif Download Security Check from here or here and save it to your Desktop.

  • Double-click SecurityCheck.exe
  • 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.

NOTE 1. If one of your security applications (e.g., third-party firewall) requests permission to allow DIG.EXE access the Internet, allow it to do so.
NOTE 2 SecurityCheck may produce some false warning(s), so leave the results reading to me.

p22002970.gif Please download Farbar Service Scanner (FSS) and run it on the computer with the issue.
  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center/Action Center
    • Windows Update
    • Windows Defender
    • Other Services
  • Press "Scan".
  • It will create a log (FSS.txt) in the same directory the tool is run.
  • Please copy and paste the log to your reply.


p22002970.gif Please download MiniToolBox and run it.

Checkmark following boxes:
  • Report IE Proxy Settings
  • Report FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices (do NOT change any settings here)
  • List Users, Partitions and Memory size

Click Go and post the result.

p22002970.gif Download Malwarebytes' Anti-Malware (aka MBAM): https://www.bleepingcomputer.com/download/malwarebytes-anti-malware/ to your desktop.

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform quick scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.

Be sure to restart the computer.

The log can also be found here:
C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt

p22002970.gifDownload Malwarebytes Anti-Rootkit from HERE to your Desktop.

  • Open the folder where the contents were unzipped and run mbar.exe

  • DO NOT click on the Cleanup button. Simply exit the program.
  • When done, please post the two logs produced they will be in the MBAR folder..... mbar-log-xxxxx.txt and system-log.txt


p22002970.gif NOTE. Make sure all logs are pasted not attached.

p22002970.gif Please download Rkill (courtesy of BleepingComputer.com) to your desktop.
There are 2 different versions. If one of them won't run then download and try to run the other one.
You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

rKill.exe: http://www.bleepingcomputer.com/download/rkill/dl/10/
iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/

  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista or Windows 7 right-click on it and choose Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • Do not reboot until instructed.
  • If the tool does not run from any of the links provided, please let me know.


If normal mode still doesn't work, run the tool from safe mode.

When the scan is done Notepad will open with rKill log.
Post it in your next reply.

NOTE. rKill.txt log will also be present on your desktop.

Hello Broni, 

 

Firstly Im really sorry for my late reply. My laptop is seriously down and always having problem booting. Diskcheck problems and disk problems while loading safe mode. As for this moment I have only completed FarbarScanner, Security Check and Minitoolbox.

 

For Malwarebytes Anti-Malware, it keeps saying overload every single time I try to remove selected. There were like 40,000+ problems detected.

 

As for Anti-Rootkit, I don't think it is still scanning, I have been waiting for 4 hours and it's not moving. 

 

Apparently for both Malwarebytes program, they both found a similar infection which is c:\Users\nyssa\AppData\Local\Temp\DWH46A1.tmp --> [Adware.Agent.ZGen] 

 

Anti-Rootkit detected 11874 Malwares

 

I couldn't post the logs as I'm posting this through my other laptop.

 

I will try posting the results from other programs as soon as possible. 

 

 

Thank you so much, I really appreciate your help. :)

Try to run MBAM from safe mode.

If the log is too huge to post here...

 

Upload the file(s) here: http://uploadmb.com/
Copy the link inside the Direct Link box and post it in your next reply.
