    I have inadvertently ran a malicious programme - how do I know it is malicious? The moment it runs it attempts to make a number of changes to the registry which I promptly denied (I have Spybot's Teatimer running). I ran a full scan with McAfee, AVG and Swatit which removed a number of trojans. All seems fine now except that ZoneAlarm alerts me that winlogon is trying to connect to an IP which I found out is in the Ukraine. I never had the prompt before, i.e. in my years of using Windows 2000 never once did winlogon.exe ever ask for internet access. I know winlogon.exe is a legit windows program, but judging from the destination, I suspect winlogon.exe has been infected, somehow. Repeated scans found nothing, and winlogon still insists on connecting to that particular IP address in Ukraine.

    I am thinking I should restore winlogon.exe from my Windows 2000 SP4 CD (I'm running that OS). Problem is, I don't quite know how - anyone? And is this the sensible step?

    * Click here to download HJTsetup.exe.
    Save HJTsetup.exe to your desktop.

    Double click on the HJTsetup.exe icon on your desktop.
    By default it will install to C:\Program Files\Hijack This.
    Continue to click Next in the setup dialogue boxes until you get to the Select Addition Tasks dialogue.
    Put a check by Create a desktop icon then click Next again.
    Continue to follow the rest of the prompts from there.
    At the final dialogue box click Finish and it will launch Hijack This.
    Click on the Do a system scan and save a log file button. It will scan and then ask you to save the log.
    Click Save to save the log file and then the log will open in notepad.
    Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.
    Come back here to this thread and Paste the log in your next reply.
    DO NOT have Hijack This fix anything yet. Most of what it finds will be harmless or even required.

    Run ActiveScan online virus scan:
    http://www.pandasoftware.com/products/activescan.htm

    Once you are on the Panda site click the Scan your PC button.
    A new window will open...click the Check Now button.
    Enter your Country.
    Enter your State/Province.
    Enter your e-mail address and click send.
    Select either Home User or Company.
    Click the big Scan Now button.
    If it wants to install an ActiveX component allow it.
    It will start downloading the files it requires for the scan (Note: It may take a couple of minutes)
    When download is complete, click on My Computer to start the scan.
    When the scan completes, if anything malicious is detected, click the See Report button, then Save Report and save it to a convenient location.
    Post the contents of the ActiveScan report.

    I you know how to use dos, you should have no problem replacing winlogon.exe . Insert the windows cd, and from there get to the command line (might be called recovery console, not really sure).

    Once there, use the copy command to copy the file to its appropiate location.


    WARNING: If you do not do this properly, windows will not boot (winlogon.exe is needed by windows (system will begin to boot, and suddenly shut off))

    I had to restart the PC and the moment Windows finished loading, I got a flurry of prompts from teatimer and Winpatrol warning me of tons of registry and startup changes. Then a pesky icon appeared in the systray warning me of malware (I know that the icon itself is a malware) - I decided to format and here I am with a clean new system.

    Thanks for the help.
