After uninstalling combofix, you could run CCleaner and remove any leftovers from AVG if it finds any.

Good job :thumbup:

The following will implement some cleanup procedures as well as reset System Restore points:

  • Click START run
  • Now type ComboFix /Uninstall in the runbox and click OK. Note the space between the X and the U, it needs to be there.

To be on the safe side, I would also change all my passwords.


This infection appears to have been cleaned, but as the malware could be configured to run any program a remote attacker requires, it's impossible to be 100% sure that any machine is clean.


Here's my usual all clean post

Log looks good :D

  • Make your Internet Explorer more secure - This can be done by following these simple instructions:
    • From within Internet Explorer click on the Tools menu and then click on Options.
    • Click once on the Security tab
    • Click once on the Internet icon so it becomes highlighted.
    • Click once on the Custom Level button.
    • Change the Download signed ActiveX controls to Prompt
    • Change the Download unsigned ActiveX controls to Disable
    • Change the Initialize and script ActiveX controls not marked as safe to Disable
    • Change the Installation of desktop items to Prompt
    • Change the Launching programs and files in an IFRAME to Prompt
    • Change the Navigate sub-frames across different domains to Prompt
    • When all these settings have been made, click on the OK button.
    • If it prompts you as to whether or not you want to save the settings, press the Yes button.
    • Next press the Apply button and then the OK to exit the Internet Properties page.
  • Update your AntiVirus Software - It is imperative that you update your Antivirus software at least once a week
    (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

  • Use a Firewall - I can not stress how important it is that you use a Firewall on your computer.
    Without a firewall your computer is succeptible to being hacked and taken over.
    I am very serious about this and see it happen almost every day with my clients.
    Simply using a Firewall in its default configuration can lower your risk greatly.

  • Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly.
    This will ensure your computer has always the latest security updates available installed on your computer.
    If there are new updates to install, install them immediately, reboot your computer, and revisit the site
    until there are no more critical updates.

Only run one Anti-Virus and Firewall program.
