Viruses and worms

My browser had been acting strange lately. New tabs would open with advertisements without me having clicked on anything. I suspected something relatively minor. After downloading Avast I began getting spammed with several warnings of the afflictions mentioned in the subject periodically. Doing a bit of reading and being unable to remove it made me a lot more concerned, and brought me here.

I believe I added all the necessary attachments. Thank you for any help you can provide; it’s greatly appreciated.

:Files C:\Windows\assembly\GAC_32\Desktop.ini C:\Windows\assembly\GAC_64\Desktop.ini C:\Windows\Installer\{872fde94-6760-d403-3fe8-fd5e9f018c80} C:\Users\Greg\AppData\Local\{872fde94-6760-d403-3fe8-fd5e9f018c80} C:\Windows\System32\services.exe|C:\Windows\winsxs\amd64_microsoft-windows-s..s-servicecontroller_31bf3856ad364e35_6.1.7600.16385_none_2b54b20ee6fa07b1\services.exe /replace

:Commands

[Reboot]


[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done
[*]Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.

THEN

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

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

  • IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

[*]Double click on ComboFix.exe & follow the prompts.
[*]Accept the disclaimer and allow to update if it asks

http://img.photobucket.com/albums/v706/ried7/NSIS_extraction.png

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

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

Here is my OTL Quick scan log.

Moving onto the next step now. Thank you for your help. :slight_smile:

Here is my combofix log.

Everything seems to be running fine. I haven’t seen anymore warnings from avast (it is back on) about Atraps or walware-gen.
Thank you Essexboy and Pondus for your help. I’ll be sure to come back and let you know if I encounter anything.

We need to replace services.exe … Click the globe under my Avatar to go to my skydrive. There you will find a file called services.exe

Download that to your C drive root… I.E C:\services.exe

  1. Close any open browsers.
  2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
  3. Open notepad and copy/paste the text in the quotebox below into it:
FCopy:: C:\services.exe|c:\windows\system32\services.exe
Save this as [b]CFScript.txt[/b], in the same location as ComboFix.exe

http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif

Refering to the picture above, drag CFScript into ComboFix.exeWhen finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Here is my new Combofix log.

Had my services.exe file still been infected, or was it damaged?

8

Nope it is now good ;D

How is the computer behaving, any problems

9

Much better now, thank you for all the help. :slight_smile:

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL
[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands [resethosts] [emptytemp] [Reboot]

[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

[*]Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
[*]In the Run box, type in ComboFix /Uninstall (Notice the space between the “x” and “/”) then click OK

http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg

[]Follow the prompts on the screen
[]A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

[*]Go to control panel
[*]Select folder options (Appearance > Folder options in category view)
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[]Click OK.

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes. Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

[*]Microsoft Windows Update
