    Hi

    A friend of mine brought his pc to me. When I opened it after 1-2 minutes windows showed an error and said that pc will restart itself 1 minute later.
    I have Microsoft Security Essentials. At the time i see the error Security Essentials briefs me about the virus. It happens at the same time. Virus container file is system32/services.exe.

    I only have 2 logs because i had no time before it reboots. Sorry about my english.

    Thanks.

    We need some additional information so that we can replace an infected system file. Boot to System Recovery Options and run FRST again. Type the below bolded text in the edit box after "Search:". services.exe Then click the Search button. It will make a log (Search.txt) on the flash drive. Please attach this log to your next reply.

    Save fixlist.txt to your flash drive.
    • You should now have both fixlist.txt and FRST.exe on your flash drive.
    Now reboot back into the System Recovery Options as you did previously.
    Run FRST and press the Fix button just once and wait.
    The tool will make a log on the flashdrive (Fixlog.txt).
    Please attach this to your next message. (See how to attach[/URL])

    Now boot into normal Windows can continue with the below.
    Running MGTools.

    Okay sorry I was in a hurry so there was a black screen asking me if i wanted start normally or wanted to repair the system.(Recommended) So I did. Now it seems to be working fine. There is no briefing about the virus. Should I run MGTools anyway?

    Yes, but not before doing this: (The last fix you were give did not correctly replace the infected file)

    NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

    Attached is fixlist.txt
    • Save fixlist.txt to your flash drive.
    • You should now have both fixlist.txt and FRST.exe on your flash drive.

    Now re-enter System Recovery Options.
    Run FRST and press the Fix button just once and wait.
    The tool will make a log on the flashdrive (Fixlog.txt).
    Please attach this to your next message. (How to attach)

    Now attempt to boot normally.

    -------------------------------

    • Now re-run RogueKiller - no fix just a scan and attach the log.
    • Re-run FRST - no fix, just a scan and attach the log.
    • Let me know how things are running at this point.
      Don't forget to run MGTools.exe! Attach mglogs.zip
