ripping issues, piglet's big adventure gamecube

[Draco Rex]

So, a few nights back i tried to rip the enemies from that GameCube came. Didn't go well, i got malware. Even after that, i wasn't sure if i was even doing the whole ripping thing right. I followed a YouTube video, but I'm not sure if I have the right programs for it. Could someone please help me? I just want the Heffalump and woolze enemies. I don't want to get burned by malware again
