This seems a little bugged as it does not appear to set an autorun of any sort.

Any of you reversing gurus know more about this out.pk file that is downloaded by the rogue at this url:

fufel-av-2.com/?action=resources&id=4974203f359

It appears to be a container of some sort that contains numerous image files and a config.txt file. It then stores this file as a reg_binary value in HKEY_CURRENT_USER\Software\Protection "registry_rsrc_parameter".

Looks like its encrypted config file , with resoucrce and image info for different flavours to pull, You can decrypt that reg binary with Xor key 44.
