BleepingComputer.com: DDS, Combofix both hang

Hullo all,
My friends laptop recently got infected with hotbar and some other malware, so far i've run malware bytes, Spybot S&D, SAS, Ad aware, hijackthis, and an eset online scan in addition to have avast installed! I've found and removed various malware with these tools so far and wanted to run DDS/combofix to futher check if the infection is in fact gone!!! However whenever i run dds/combofix/gmae they hang and i end up having to hold down the power button to restart! I have left all of the said apps running for hours before killing the machine! Even tried running them in safe mode in combination with rkill (which according to the logs only kills a realtek process)! I disabled (and eventually uninstalled) malwarebytes, spybot, sas, ad aware just in case they were interfering with the tools but still no joy! Is this a sign that there is a particular infection that could be cuasing this???

Can anyone help me please? Thanks in advance!

No one should be using ComboFix unless specifically instructed to do so by a Malware Removal Expert who can interpret the logs. It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. When issues arise due to complex malware infections, possible false detections, problems running ComboFix or with other security tools causing conflicts, experts are usually aware of them and can advise what should or should not be done while providing individual assistance. Those attempting to use ComboFix on their own do not have such information and are at risk when running the tool in an unsupervised environment. Please read the pinned topic ComboFix usage, Questions, Help? - Look here.

There are circumstances ComboFix will hang or stall at various stages due to malware interference, failure to disable other real-time protection tools and 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. While that is not normal behavior, it is not unusual. In such cases, it is helpful to know at what stage CF stalled and to provide that information to the Helper who is assisting you so they can investigate. That's just another reason you should only use ComboFix under supervision.
