Possible lsass.exe Infection

  1. Greetings,

    I recently experienced uncontrolled restarts with an error message indicating an error with lsass.exe. A google search revealed these are symptoms of the W32.Sasser worm, but it is only speculation at this point. I was finally able to get into Windows so hopefully the virus can be removed without wiping the system. I'm running Windows XP and have Norton AntiVirus 2010 installed. Attached are my log files. Please advise.

    Thanks in advance,

    Hey Broni,

    Glad you're still around! No, this time it's my wife's computer. My computer has been working great since our last malware removal session.

    Please download ComboFix from Here or Here to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    1. Please, never rename Combofix unless instructed.
    2. Close any open browsers.
    3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
      • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
      • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
      NOTE1. If Combofix asks you to install Recovery Console, please allow it.
      NOTE 2. If Combofix asks you to update the program, always do so.
      • Close any open browsers.
      • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
      • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
      • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    4. Double click on combofix.exe & follow the prompts.
    5. When finished, it will produce a report for you.
    6. Please post the "C:\ComboFix.txt"
    **Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!
