Did ComboFix leave a log by chance? If it's there, please post it (C:\ComboFix.txt).
Delete your version of RootRepeal, download it again and post back a new log, along with a fresh OTL log.
Also download this tool to desktop:
http://www2.gmer.net/mbr/mbr.exe
Double click it & post the log it creates on desktop. (mbr.log)
