Just noticed this topic by chance
SDFix is my tool and isnt a general remover, it was made for specific backdoor infections which are listed Here
. I agree that it's not something most home users would ever need and when it is used it should really be on a forum environment with supervised help.
The process killer used in my tool is from BeyondLogic.org
and isnt a threat but it could be if it was added to the system by malware as it would then have the ability to stop any process it wants, for my tool its only used if malware is hooking to explorer.exe which would mean its also running in Safe Mode, if that is the case the process killer is used to stop the malware file before the repairs are started. If you havent done so already please delete the C:\SDFix folder and the SDFix.exe file from your desktop (or location you saved it to) to prevent more alerts.
Hope that helps and all the best for 2007
