Hey guys, I have a strange issue with a blank command window popping up and immediately disappearing. It happens exactly 10 minutes after booting up, every time. This is happening on a fairly new installation of Windows 7 64bit.

 

I'm trying to understand if its malware related or what exactly is triggering it. I've looked in msconfig startup tab for any entries that call cmd.exe but found none. I also looked in task scheduler but couldn't find anything that seemed related.

 

Can anyone advise on how to identify what is calling this command window? What tool might be able to help?

 

I'd appreciate any help. Thanks!

Hi there,
my name is Marius and I will assist you with your malware related problems.

Before we move on, please read the following points carefully.

  • First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
  • Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
  • Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
  • Stay with me. I will give you some advice about prevention after the cleanup process. Absence of symptoms does not always mean the computer is clean.
  • My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.

  • In the right panel, you will see several boxes that have been checked. Uncheck the following ...
    • Sections
    • IAT/EAT
    • Show All ( should be unchecked by default )
  • Leave everything else as it is.
  • Close all other running programs as well as your Browser.
  • Click the Scan button & wait for it to finish.
  • Once done click on the Save.. button, and in the File name area, type in "ark.txt" or it will save as a .log file which cannot be uploaded to your post.
