My computer was lagging and running slow and I followed the instructions I found on the Internet and on BC to clean it up (Defragment, Clean Disk, Add-Ons, etc.) I did everything from updating Windows, running anti-spyware (Walwarebytes Anti Malware) and virus scans (ABG)in regular and safe mode, chkdsk, etc., etc. AVG caught a "Trojan Horse Dropper Generic 7.SIF" and I had difficulty removing it so I did a Destructive Reinstall of Windows XP with the disc that came with the computer.

I don't know much about computers but after the fresh reinstall, I could see that there were settings that just didn't look right and had been altered:

1. The System Restore was turned Off;
2. The Remote Access was turned On;
3. In Control Panel>Internet Options>Security, I noted that certain settings were altered. For ex., in the "Internet, Local Intranet, Trusted Sites, Restricted Sites" I saw that the "Launch Unsafe Application and Files" was Enabled. I am not experienced enough to know what half of these settings are, but I am guessing that this shouldn't have been enabled;
4. In the Firewall, the WEBFramework and UPnP Framework were Unblocked for "Any Computer."


Attached are DDS logs. I have Windows XP, Media Center Edition, Version 2002, SP 3. Any guidance would be greatly appreciated. Thanks - EileenNOLA

Hello, Welcome to BleepingComputer.
I'm nasdaq and will be helping you.

If you can please print this topic it will make it easier for you to follow the instructions and complete all of the necessary steps.
===

Please download ComboFix from one of these locations:

Link 1
Link 2

* IMPORTANT !!! Save ComboFix.exe to your Desktop

  • Disable your Anti-Virus and Anti-Spyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools
  • Close any open browsers, and all other programs working. Make sure you save your file if working on a document.
  • Do not install any other programs until this if fixed.[/b]
  • Double click on ComboFix.exe & follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
  • Some Rookit infection may damage your boot sector. The Windows Recovery Console may be needed to restore it. Do not bypass this installation. You may regret it.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Posted Image

Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

Note: If you have difficulty properly disabling your protection programs, refer to this link --> http://www.bleepingcomputer.com/forums/topic114351.html

Do not mouse click ComboFix's window while it's running. That may cause it to stall

Note: If after running ComboFix you get this error message "Illegal operation attempted on a registry key that has been marked for deletion." when attempting to run a program all you need to do is restart the computer to reset the registry.
===

Third party programs if not up to date can be the cause of infiltration an infection.

Please run this security check for my review.

Download Security Check by screen317 from here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and 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.
===

Please download AdwCleaner by Xplode onto your Desktop.
  • Double click on AdwCleaner.exe to run the tool.
  • Click on Search.
  • A log file will automatically open after the scan has finished.
  • Please post the content of that log file with your next answer.
  • You can find the log file at C:\AdwCleaner[Rn].txt (n is a number).

Please post the logs and let me know if the problem persists.

When prompted, I tried to install the Windows Recovery Console but was told that an active internet connection wasn't available (the internet is working fine.) I tried installing it a few times but every time I was told that I didn't have an internet connection. Thanks. -eileenNOLA

The logs are looking good.

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
  • 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.

Please let me know what problems persists.

I'm still having problems in that the computer is slow. It lags for 30-60 seconds when I am Googling something. Or when I am navigating from one web site to another, it takes forever.

When it slows, I note that the CPU spikes (I can hear the motor humming)and I see web sites such as "Cyclops.com, Pumbatic.com, Showads.com" flashing across the bottom of my screen. The Internet says that this is probably tracking cookies but I don't know how to fix it. I downloaded "Do Not Track Me" which has helped a little bit but the problem persists. Thanks! -eileenNOLA

I'm not sure if the attachment is what you want. I was unable to run GooredFix as the Administrator. There's no Administrator with a password on this computer (this is my computer and I'm the only one who uses it). I was only able to run it as Eileen, the "User." When I tried to run it as the Administrator, I am prompted to enter a password. I tried just hitting Enter, but that doesn't work either. Thanks again. -eileenNOLA

I did the ipconfig /flushdns instructions you gave to me. I'm glad you told me to leave a space :)

If still having the same problem disable one at a time these 2 extensions.

Test your speed.

If still slow disable donottrackplus@abine.com

I apologize for taking so long to get back to you!  I guess when you see that there's no news that things have improved.unsure.png

 

The computer is working faster and the typing isn't lagging anymore.  Maybe it was the the ipconfig/flushdns that cleared things up(?) The CPU still shoots up and it lags a bit when that happens but it's nowhere near as bad as before, when I couldn't even type. 

 

If you have any other suggestions, then that would be great.  You wrote that the logs look OK so maybe my problems can't be fixed because this is a Windows XP computer(?)  Thank you so much, and my apologizes for not getting back to you. -EileenNOLA

Please refer to my post No 9.
 
I know about this Firefox extension donottrackplus@abine.com
 
However I have difficulties in finding relevant information on idme@abine.com
 
Did you try to disable one or possibly both of these extensions?
 
Both working in real life may be causing some problems.
 
What can you tell me about idme@abine.com
