Your problems can be many, from not turning all your Anti-virus and Anti-malware program off, to not having an infection that ComboFix relates to.
Even some computers and systems will not run ComboFix (XP 64bit for example)

Please reboot then go Start > Run > and type or copy / paste, Combofix /Uninstall (note the space between x and / ) and click OK and reboot -

If you think that your computer is infected, please post a New Topic in Malware Removal area of the forum, and only post the logs requested for an Expert to review

Thank You -

There are circumstances ComboFix will hang, crash or stall at various stages due to malware interference, failure to disable other real-time protection tools or the presence of CD Emulators (Daemon Tools, Alchohol 120%, Astroburn, AnyDVD) so that it does not complete successfully. Also, depending on how badly a system is infected, ComboFix may take longer to complete its routine than it normally does or fail to run properly. While that is not normal behavior, it is not unusual. This is just another reason why you should only use ComboFix under supervision.

It's best to follow noknojon's instructions to follow the Preparation Guide and start a New Topic in the Malware Removal forum where you can post the required logs.
