I’ve had many users claim to see a pop-up ad after accessing the site, it seems to redirect after a second or two of being on the site to a ‘Congratulations – You’ve Won’ ad. The URL it redirects to is happy.goodluckspace.
I’ve ran various scanners on the site including Sucuri and have Wordfence installed and active. I cannot find anything and the pop-up seems to happen sporadically and not to all users. I’ve had around 20 users contact me showing me the same pop-up and redirect.
Any help on this would be greatly appreciated.
