Hi,
I have a computer which has been infected with a virus. I have removed everything I can find that could be associated with it and virus scanning software such as Malwarebytes, Spybot, Trend, CA, are unable to detect it. It creates a random 6 character name exe file on logon which is stored in C:\Windows\Temp and runs it. I am able to kill the task and delete the file but am unable to find the root cause of this creation. Here is the ComboFix log. On this instance the file that was created after ComboFix rebooted the workstation is c:\windows\temp\BU9CCA.EXE.

ComboFix logs should not to be posted or discussed outside the HijackThis forums. It is an extremely powerful tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use. Please read Combofix's Disclaimer. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

Please create a new topic in the Am I Infected forum.
http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/
Explain the nature of your problem. Describe pop-ups and system tray or desktop icons that have appeared. Explain what is "going wrong" with your computer. Note any tools you have used and their respective results.

If needed, we will direct you to our HJT Preparation Guide.
