Yes and no. The notifications are harmless. However, if you receive one that seems like clickbait, don't click on it. Your device may be infected with malware, causing you to receive notifications baiting you to open them. If you do click on one, there's a chance you'll be directed to a questionable website. However, not clicking on them won't compromise your device. If you feel you may have malware on your computer, it's best to run your anti-virus or malware detection app.
