It does not indicate a virus. It just means some scammer has your email address in their list of emails. Even people who don’t own any Apple devices nor have an AppleID will sometimes get these mass emailed scam messages. Just as Mac users get emails about virus infections for viruses that only infect Windows operating systems.
Scammers just mass email every single valid email address they can get their hands on. It’s a numbers game - send out many millions of such messages (cheap to do) and a handful of successful clicks is enough to make the effort pay off. But they don’t care who they are sending to, nor know thing one about any of them.
