However, there are a few hints that such as email is anything but legitimate, as pointed out on the Symatec Security Response blog:
“the spoofed URL in this latest scam redirects visitors to dynamic domain names with seemingly unusual top level domains (TLDs), such as .li, .ch, and .es. […]
The domains that are used to impersonate the YouTube Web site are giower.li, fineir.ch, and be4koy.com.es. These TLDs are not the usual .com or .net domains. The links will force the download of a malicious executable “install_flash_player.exe,” which in fact is a threat already detected by Symantec.”
So, if Hans sends you an email in the near future, please do your best and click on the delete button instead of clicking on the provided link.
