I check with Avast online security this is a safe site.
Dr. Dave’s website has been around for ages; I’ve never had a problem with it. I accessed it on another computer, and there is an ad that says you need to update your flash player, but whether it shows up or not seems to depend on the browser you use.
(This site isn’t what I’ve always understood ‘clickbait’ to be; it’s just a lot of funny/interesting videos.)
