My laptop fell victim to the Gumblar.cn malware. I have done a system restore but I am not convinced that the malware is out. My Windows update is showing that the last update was on April 14, 2009, so I believe there is still a malware that is suppressing the Windows update. I have scanned my laptop with both Malwarebytes and AVG, and it is supposed to be clean. Below is the log file. Any help would be appreciated!

Please note that all instructions given are customised for this computer only,

If you think you have similar problems, please post a log in the HJT forum and wait for help.

Hello and welcome to the forums

My name is Katana and I will be helping you to remove any infection(s) that you may have.

Please observe these rules while we work:
  1. Please Read All Instructions Carefully

  3. Please do not run any other tools or scans whilst I am helping you
  4. Failure to reply within 5 days will result in the topic being closed.
  5. Please continue to respond until I give you the "All Clear"
    (Just because you can't see a problem doesn't mean it isn't there)

If you can do those few things, everything should go smoothly

Please Note, your security programs may give warnings for some of the tools I will ask you to use.
Be assured, any links I give are safe
