In fact, your licenses for this product and NOD32 are interchangeable. Like ESET NOD32 Antivirus, ESET Cyber Security costs $39.99 per year for one license, and $10 per year apiece for each additional license, up to five. How Much Does ESET Cyber Security for Mac Cost?

Yes, they’re not as luscious a target for malware coders as PCs are, but macOS malware, including ransomware, exists. But Macs don’t actually have the superpowered invulnerability promoted in those ads. Remember those old TV ads touting the “fact” that PCs get viruses and Macs don’t? At least they succeeded in hammering home the need for antivirus on a PC.
