Hello,



They call me TwinHeadedEagle around here, and I'll be working with you.



Before we start please read and note the following:
  • At the top of your post, please click on the "Watch thread" button and make sure to check Watch this thread...and receive email notifications. This will send an email to you as soon as I reply to your topic, allowing me to solve your problem faster.
  • Please do not install any new software during the cleaning process other than the tools I provide for you. This can hinder the cleaning process. Please do not perform System Restore or any other restore.
  • Instructions I give to you are very simple and made for complete beginner to follow. That's why you need to read through my instructions carefully and completely before executing them.
  • Please do not run any tools other than the ones I ask you to, when I ask you to. Some of these tools can be very dangerous if used improperly. Also, if you use a tool that I have not requested you use, it can cause false positives, thereby delaying the complete cleaning of your machine.
  • All tools we use here are completely clean and do not contain any malware. If your antivirus detects them as malicious, please disable your antivirus and then continue.
  • If during the process you run across anything that is not in my instructions, please stop and ask. If any tool is running too much time (few hours), please stop and inform me.
  • I visit forum several times at day, making sure to respond to everyone's topic as fast as possible. But bear in mind that I have private life like everyone and I cannot be here 24/7. So please be patient with me. Also, some infections require less, and some more time to be removed completely, so bear this in mind and be patient.
  • Please stay with me until the end of all steps and procedures and I declare your system clean. Just because there is a lack of symptoms does not indicate a clean machine. If you solved your problem yourself, set aside two minutes to let me know.
  • Please attach all report using
    fjqb1h.png
    button below. Doing this, you make it easier for me to analyze and fix your problem.

  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay for the repair.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.

Running it on another one may cause damage and render the system unstable.

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on
    FRST.gif
    icon and select
    RunAsAdmin.jpg
    Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.

No long procedures without any cause and no loss of network connection due to timeout. So far so good. I'll try for another day before declaring victory. Will write again tomorrow after further experience.

Everything seems to be working fine; no interruptions, strange shutdowns or persistent processes. Thanks for your help. Do donations go to you or are they shared among the experts?

Yes, donations go to me.


Glad I could help. We will delete all used tools and I'll give you some tips to harden your security and learn how to protect yourself :)

MUST READ - general maintenance:


The Importance of Software Updating:

In order to stay protected it is
very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.

Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.




Recommended additional software:
icon_arrow.gif
CCleaner - to clean unneeded temporary files.
icon_arrow.gif
Malwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gif
Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gif
McShield - to prevent infections spread by removable media.
icon_arrow.gif
Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gif
Adblock - to surf the web without annoying ads!



Post-cleanup procedures:


Download DelFix by Xplode and save it to your desktop.
  • Run the tool by right click on the
    51a5ce45263de-delfix.png
    icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run and wait until the tool completes his work.
  • All tools we used should be gone. Tool will create an report for you (C:\DelFix.txt)
The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.



My help is free for everybody.
If you're happy with the help provided and/or wish to buy me a beer for the assistance you received, then you can consider a donation:
Thank you!​




Stay safe,
TwinHeadedEagle :)

Guess I spoke too soon. Came back to my computer after being gone for 1 hour. Unresponsive with black screen; no response to attempts to start task manager to see what was going on. Tried until got the beep for too much unprocessed input. Shut down machine after 20 minutes of non-response.

Rebooted to send this to you. What's next?

Previously, I had returned after 1 hour to a black screen. Attempts to start Task Manager were unsuccessful and after getting the beeps from too much in the input queue I waited 20 minutes. Still constant I/O to the disk drive and unresponsive so I shut it down.

What now? {prior post was actually after this one by a few hours]

Use the Windows Error Checking utility (Check Disk), with the options to fix file system errors and scan the disk surface for errors, attempt recovery of data and repair the disk:

  • Click the "Windows Orb" Start button, then click Computer.
  • Right-click on the drive that you wish to check > Properties > Tools tab
  • In the "Error checking" section, click on Check now.
  • Place a checkmark in both boxes > Start.
  • If the disk you have chosen is the Windows system disk:
  • A message will notify you that a restart is necessary ask "Do you want to check for hard disk errors the next time you start your computer?".
  • Click Schedule disk check > OK and close all windows.
  • Re-start the computer. The disk will be checked when the system boots.
  • This will take some time to run and at times may appear stalled but just let it run.
  • When the disk check is complete, the system will re-start automatically and load Windows.


A log of the disk check is recorded only if the scheduled re-start is used, and only for drives on the same HDD as the Operating System.
To open Event Viewer and view the log:

  • Click the "Windows Orb" Start button -> type "eventvwr" without the quotes -> press the key.
  • The Event Viewer window will open.
  • In the left pane, expand "Windows Logs" and then click on Application.
  • In the right pane, at the top, click on the column heading Source to sort the list alphabetically.
  • Look in the Source column for "Wininit", with an entry corresponding to the date and time of the disk check.
  • Click on that Wininit entry to select it.
  • On the top main menu, click Action > Copy > Copy Details as Text.
  • Paste the contents into your next reply.

I went through the process and found no file with the date today. After repeating the entire sequence again there still was no such file created. I did use the scheduler and the restart and the disk scanned is the C drive where everything is I believe.

Not sure what I may be doing wrong. I checked the system date to make sure it was 8/10/15 and it was. No log entry with that date.

So far this morning it seems to be working fine. Should I proceed with the clean-up tasks you mentioned when we thought we were done before?

OK, two days with no odd processing or interruptions. I will proceed with the additional security and clean-up tasks that you suggested. Thank you again for your help and patience.
