Hello,

I maintain six computers in a school, used by staff. Almost all the time the computers run fast and do their tasks acceptably. But once every week or two the machines become unusable, showing symptoms of significant resource starvation, which I refer to here as "lockup":
1. The machines are in a logged-in state, or have timed out from logged-in via the screen-saver.
2. Ctrl-Alt-Del results in message "The application failed to initialize properly (0xc00000017)."
3. Starting Winword.exe 2003 results in "Not enough quota is available to process this command."
4. Trying to make a new folder on Desktop results in message "Insufficient system resources exist to complete the requested service."
5. Double-clicking on the Time in Systray results in mesasge "Windows cannot find 'C:\Windows\System32\rundll32.exe."
6. Google Desktop says it is not running.
7. GoToMyPC says it is not connected to Internet (though the connection exists physically and is competent)
8. All other actions result in no response (Rt-Click on the taskbar or Desktop, or click on Firefox, My Computer, My Network Places, Start)
9. If I click on the Power button, the system shuts down in an orderly way, unprompted by me. Restart results in normal operation until the next lockup.
10. The computers are all Dell Optiplexes of different ages, up to 3 years. One is brand new.
11. The computers tend to lock up on weekends. I have removed one computer to an outside location but it still locked up after a few days.
12. The symptom 11 (weekend lockup) led me to guess that the lockup is triggered by user inactivity. Evidence: I have been able to prevent one machine from entering this state by running a scheduled task every 24 hours, when it sends me an email. At least this has worked for the last 2-3 weeks.

I have done a boot-time scan with the most recent versions of antivirus sw avast! (Alwil), G-Data (Germany), Housecall (Trend Micro), Stinger (McAfee) and Norton AV 2010 (Symantec). All scans were full. No viruses were detected. I have also done a full scan using Malwarebytes, nothing detected. I am uploading a HijackThis log run on the one computer located outside the school.

I am not sure this is virus-related, but I cannot think what else might be causing it. Thaks for any help or suggestions if I have mis-post.

Hello,

My name is Syler and I will be helping you to solve your Malware issues. If you have since resolved your issues I would appreciate if you
would let me no so I can close this topic, if you still need help please let me no what issues you are still having, in your next reply.

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and
we are trying our best to keep up.

  • 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 (<<will be maximized) and info.txt (<<will be minimized)

  • 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)
    • Zip 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, as this process may crash your computer.
  • Temporarily disable any real-time active protection so your security program drivers will not conflict with gmer's driver.
  • Double click on Gmer to run it.
  • Allow the gmer.sys driver to load if asked.
  • You may see a rootkit warning window, If you do, click No.
  • Untick the following boxes on the right side of the Gmer screen.

    Files
    Show All
  • Click on Posted Image and wait for the scan to finish.
  • If you see a rootkit warning window, click OK.
  • Push Posted Image and save the logfile to your desktop.
  • Copy and Paste the contents of that file in your next post.



Then please post back here with the following:
  • log.txt
