The process "winlogon.exe" runs in the background. Winlogon is a part of the Windows Login subsystem, and is necessary for user authorization and Windows XP activation checks.

Note: The winlogon.exe file is located in the folder C:\Windows\System32. In other cases, winlogon.exe is a virus, spyware, trojan or worm! Check this with Security Task Manager.

Virus with same name:
W32.Netsky.D

Hello and welcome to the BleepingComputer.com! :thumbup2:

I will be helping you today. :)

In the upper right hand corner of the topic you will see a button called Options. If you click on this in the drop-down menu you can choose Track this topic. By doing this and then choosing Immediate E-Mail notification and then clicking on Proceed you will be advised when we respond to your topic and facilitate the cleaning of your machine.

After 5 days if a topic is not replied to we assume it has been abandoned and it is closed.

Please refrain from running tools or applying updates other than those we suggest while we are cleaning up your computer. The reason for this is so we know what is going on with the machine at any time. Some programs can interfere with others and hamper the recovery process.

Please give me some time to analyse your logs, I will be back shortly.
regards,
schrauber

Hello, axlee and again
Welcome to the Bleeping Computer Forums. My name is Thomas (Tom is fine), and I will be helping you fixing your problems.

If you do not make a reply in 5 days, we will have to close your topic.

You may want to keep the link to this topic in your favourites. Alternatively, you can click the Posted Image button at the top bar of this topic and Track this Topic. The topics you are tracking can be found here.

Please take note of some guidelines for this fix:
  • Refrain from making any changes to your computer including installing/uninstall programs, deleting files, modifying the registry, and running scanners or tools. Doing so could cause changes to the directions I have to give you and prolong the time required. Further more, you should not be taking any advice relating to this computer from any other source throughout the course of this fix.
  • If you do not understand any step(s) provided, please do not hesitate to ask before continuing. I would much rather clarify instructions or explain them differently than have something important broken.
  • Even if things appear to be better, it might not mean we are finished. Please continue to follow my instructions and reply back until I give you the "all clean". We do not want to clean you part-way, only to have the system re-infect itself.
  • Please reply using the Posted Image button in the lower right hand corner of your screen. Do not start a new topic. The logs that you post should be pasted directly into the reply. Only attach them if requested or if they do not fit into the post.
  • Old topics are closed after 3 days with no reply, and working topics are closed after 5 days. If for any reason you cannot complete instructions within that time, that's fine, just post back here so that we know you're still here.
  • Please set your system to show all files.
    Click Start, open My Computer, select the Tools menu and click Folder Options.
    Select the View Tab. Under the Hidden files and folders heading, select Show hidden files and folders.
    Uncheck: Hide file extensions for known file types
    Uncheck the Hide protected operating system files (recommended) option.
    Click Yes to confirm.





One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards.



If you decide to clean it, please follow the instructions below.



Step 1
  • Download random's system information tool (RSIT) by random/random from here and save it to your desktop.
  • Double click on RSIT.exe to run RSIT.
  • Click Continue at the disclaimer screen.
  • Once it has finished, two logs will open. Please post the contents of both log.txt (<info.txt (<





Step 2

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.







Please post back with:
  • Both RSIT-Logfiles
  • Gmer-Logfile

schrauber
