ComboFix is optimized
to run from normal mode where it is most effective. However, it should run in safe mode if you are having trouble getting it to run or loading Windows in normal mode. As to why it (or RKill) is not showing on your desktop after booting in save mode....not sure why without more information. Have you tried saving the files to a download folder instead of the Desktop?
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. We recommend that people should not be using ComboFix without being advised to do so by a trained expert (see here
) who is assisting them deal with a malware problem. When issues arise due to complex malware infections, 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.
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 a strategy for effective disinfection and a determination if using ComboFix is necessary.
While our policy is not to offer advice on running ComboFix unless we asked someone to run it, we are willing to assist with resolving problems caused after using it and we are certainly willing to help with malware disinfection. If that assistance requires running ComboFix, you will be advised what to do in order to get the tool to run properly or investigate any error messages.
If you need individual assistance with a malware infection, please follow the instructions in the Preparation Guide For Requesting Help
