Hi, first of all I say I’m spanish so i don’t know if you will be able to understand be, but I try it.
Today I think when I have a ¿false? update of adobe flash player, suddenly appeared in my antivirus the next message:

BLOCKED MALWARE
Object: C:\Windows\Installer{24170ae6-20bc-da6c-9048-2465aee7a9f}\U\80000000.@
Infection: Win32 Malware-gen
Action: move to trunk
Proccess: C:\Windows\System32\services.exe

Since then, the same message appears every 5 minutes, I dont know if it is a real message or a false message.
I have tried 1000 ways to remove the virus buto I couldn’t
If anybody could help me I would be really greatful

follow this guide and attach (not copy and paste) logs from malwarebytes / OTL / aswMBR
http://forum.avast.com/index.php?topic=53253.0

Logs attached. I hope it is well attached
I had a problem with aswMBR because when it was scanning in: Windows\assembly\GAC_MSIL\Microsoft.VisualStudio.ToolsAplications… suddenly stopped running, a Windows problem happened and only could exit from the program, so I only could save the log a bit before.

OK we are missing a file to replace the infected services, I will see if Combofix can find a spare. If not I will upload a copy

  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:
RESTORE:: 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.

Log attached.
Moreover I’m having problems with Internet, I think it is caused by the virus. Internet sometimes not runs neither with Internet nor Chrome, but for example MSN yes. But with https:// it runs. I dont know if explorer.exe is damaged…

There are so may ways for it to get on your system that I could not say for sure

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.
