The recently launched Nintendo Switch is the latest video game console released by Nintendo.  Software emulators for the Nintendo Switch are being offered online in many places including YouTube where thousands of videos can be found offering Nintendo Switch emulators.  Emulators permit someone to play console-only games on their portable devices such as their smartphones or tablets.  Nintendo does not make such an emulator.  People going to one of these phony Nintendo Switch emulator websites are generally directed to a survey that they must complete in order to receive the code necessary to use the offered emulator, however, this is a scam and while completing the survey provides the scammers with rewards because they are paid by marketers for each completed survey they supply, the person trying to get the emulator ends up with nothing.  Even worse is the very real possibility that someone downloading attachments for what they think is a Nintendo Switch emulator will be downloading malware that can either lead to identity theft or ransomware malware.
The phony Nintendo Switch emulator scam was uncovered by Symantec, a security company.
TIPS
There presently is no emulator for the Nintendo Switch, so any online offer of one at this time is a scam.  Being directed to a survey when you are attempting to locate something free on the Internet is always a source of concern for while there are legitimate surveys that will provide you something in return, such as a chance at winning a gift card, many of these surveys are scams providing nothing in return.  Finally, as always never click on links or download attachments unless you have absolutely confirmed that the link or download is legitimate.  The risk of downloading dangerous malware is too great.
