Dear fireman4it,

This worked as magic to clean up the system.
My system seems to perform well. Earlier I am not able to install Microsoft essentials, but after your procedure, things are quiet good. Thanks a million.

However I see a Net Protector 2010 in the windows login screen, but that program was not in the installed list as I have uninstalled that anti virus long back. You can see that in the combofix.txt. how to delete that. Thanks a lot once again

Regards,
Control engineer.

Hello,

We are dealing with a very nasty File infector. We may not be able to clean up the machine as it inject code into some crucial operating files. We will give it a go though. :)

1.
We need to run a CFScript.

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 codebox below into it:

killall::

File::
C:\mhskmy.exe
C:\jghuej.exe
C:\quftqc.exe
C:\sibpo.exe
C:\msjpev.exe
c:\\DOCUME~1\\HOME\\LOCALS~1\\Temp\\winiatxl.exe
c:\\DOCUME~1\\HOME\\LOCALS~1\\Temp\\suyony.exe

SecCenter:: 
AV: Net Protector 2010 *Enabled/Updated* {5AE99E99-35D6-47B8-87C2-D8A82C07FB43}


Save this as CFScript.txt, in the same location as ComboFix.exe

Refering to the picture above, drag CFScript into ComboFix.exe

When finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Hello,

I have very bad news. We are dealing with a a polymorphic file infector. Virus:Win32/Sality is a detection for a virus that spreads by infecting Windows executable files and by copying itself to removable and remote drives. It also terminates various security products, prevents certain Windows utilities from executing and attempts to download additional files from a predefined remote Web server.

You are infected with Sality.
http://www.symantec.com/security_response/writeup.jsp?docid=2006-011714-3948-99&tabid=2


If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. You should change each password using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:Sality is not effectively disinfectable. Your best option is to perform a full reformat as there is no guarantee this infection can be completely removed. In most instances it may have caused so much damage to your system files that it cannot be completely cleaned or repaired. In many cases the infected files cannot be deleted and anti-malware scanners cannot disinfect them properly. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Please read:

If you insist on trying to fix this infection instead of following our advice to reformat and reinstall your operating system, there are some tools and various rescue disks available from several anti-virus vendors. Keep in mind there is no guarantee the repair will be successful and you may need to try more than one. Even vendors like Kaspersky say there is no guarantee that some files will not get corrupted during the disinfection process. This means that infected executables and system files can become unusable after attempting to repair them and there's still no quarantee the virus is really gone. Since many of these are legitimate critical files required by the operating system, deletion is not a viable option. This destructive behavior may be by design as explained in File Infectors: To Junk Or Not To Junk.

In my experience, users may find their system performing better for a short time after attempted disinfection only to have it become progressively worst again as the malware continues to reinfect thousands of files. Some folks will try every tool or rescue disk they can find in futile attempts to repair critical system files. If something goes awry during the malware removal process the computer may become unstable or unbootable and you could loose access to all your data. In the end most folks end up reformatting out of frustration after spending hours attempting to repair and remove the infected files.
Bleeping Computer DOES NOT assume any responsibility for your attempt to repair this infection using any of the following tools. You do this at your own risk and against our advice.
