Hello Yourhyness and welcome to BC.
As a general policy, Bleeping Computer does not offer advice
on how to run ComboFix unless we asked someone to run it or if there is a problem with the computer caused by running the tool. This is because people should not be using ComboFix without being advised to do so by a trained expert (see here
) who is assisting a member deal a malware issue on that system. When issues arise due to complex malware infections, possible false detections, problems running ComboFix (i.e. stalling, hanging, crashing) 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. When false detections are identified, experts have access to the developer and can report them so he can investigate, confirm and make corrections. 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.
clearly says it is permitted for non-commerical purposes only
and should not be used in an unsupervised environment. The developer did not intend for his tool to be used any other way and it certainly was not intended
for those running a computer repair business or for use in a business/corporate environment.
With that said, there are circumstances ComboFix will hang
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. In such cases, it is helpful to know at what stage CF stalled/crashed and to provide that information to the Helper who is assisting you so they can investigate. This is just another reason why you should only use ComboFix under supervision.
Also be aware that using ComboFix is only one part of the disinfection process. Preliminary scans from other tools like DDS
should be used first because they provide comprehensive logs with specific details about files, folders and registry keys which may have been modified by malware infection. Analysis of those logs allows planning an strategy for effective disinfection and a determination if using ComboFix is necessary.
