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 (i.e. Malware Response Team) 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 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.

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.
