How can I remove antivirus software off one machine and put it on another?

Episode 1080 (1:57:12)

Zack from Los Angeles, CA

Zack has an old Windows Vista machine. He uses ESET's Nod32 and wants to know if he can remove it from one computer and put it onto another. Leo says that can be tricky because AntiVirus software is designed not to be uninstalled, otherwise malware would do that. So he may need to spend some time over at ESET's support page to learn how to correctly do that.
