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. 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. 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.
Further, 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.

- If you cannot complete a step, then skip it and continue with the next.
- In Step 7 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.
- When you have done that, post your log in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team Experts.
- If you already ran ComboFix, include the log (ComboFix.txt) in your topic. It should have been saved to your root directory, usually C:\.
