When it comes to online scams, common sense often beats every "Internet Security" product out there.
To give a good example, I know of one Irish tourist website that has been infected since I checked a week ago (someone originally asked me after they had an awful experience trying to access the site). After having little luck contacting the webmaster, I submitted it to Google (Monday I think) so that it would be temporarily flagged until the webmaster gets it fixed.
Now about a week later, it remains showing up in Google search results as I check and it still redirects unsuspecting visitors to rogue websites, e.g. Fake infection alert pages, fake you're today's winner, etc. pages. Although I've MalwareBytes 3.0 running, not once did it block any of the pages each time I got redirected checking the website. Firefox did catch one redirection, bringing up the red "Deceptive website" warning page.
So a week later with this website redirecting unsuspecting tourists to rogue sites, only two products have flagged the website as malicious according to VirusTotal:
The webmaster came back to me a day ago, so hopefully they will get it cleaned. I also don't want to name the site with the owner being just a short distance away. Feel free to PM me for it.
