    I have read about a similar log which was sent to you by 'batman187' , but I was not able to understand it because it was written in finnish.

    Could you please help me ? Thank you very much !

    Ok.

    First, move HjT into its own folder -> C:\HjT\HijackThis.exe

    Then fix with HjT (do a system scan only, mark these and press fix checked):

    O4 - HKLM\..\Run: [Windows Locator] locate.exe

    Then make your hidden and system files visible ->
    http://www.xtra.co.nz/help/0,,4155-1916458,00.html

    Boot in safe mode (press F8 while booting until you see a menu. Select safe mode from that menu)

    Delete these files, if found:

    C:\WINNT\system32\==>MStools1.exe<==
    C:\WINNT\web\==>related.htm<==
    C:\WINNT\system32\==>locate.exe<==

    Reboot and send a fresh HjT-log.

    Thanks for the detailed writeup: now the problem is solved !

    I applicated these tasks:
    1. fix with HjT
    2. made hidden and system files visible
    3. updated my McAfee virus definitions
    4. boot in safe mode
    5. scanned the system
    6. McAfee found the file c:\winnt\system32\MStools1.exe infected by the virus W32/Sdbot.worm.gen.bh
    7. delete the file.

    Many thanks and happy New Year !
