Removal of the replicant is also required, look for files ending in
".exe" or ".dll" in the :\Windows\ or :\Windows\System\
folders that use alphanumeric file names. The name of the replicant may
be in one of the registry keys above.
A machine reboot is required to clear the existing process from running
in memory.
