also worth noting, when I'm on WiFi the popup appears nearly everytime i visit lowyat forum. But when switch to data there's no popup, as soon as I switch to wifi the popup is back 

Having the same issue here as well..using a galaxy s6 here..though was my phone that got infected or something..almost on the edge of resetting the phone..it happen both on wifi and mobile data..below are the screenshot of the history of my chrome browser when the pop up happen..sometimes chrome will manage to block it but most of the time not..

one weird thing I notice is that it will only happen on the mobile version of the forum and not the desktop version eventhough it is access through the phone browser..and it has been happening for the past few days.. 

Yes I started getting these ads when I got my new nexus 6P back in June and now getting worst till the point I cannot tahan ady.
Can the mods please give us some clarification damn it?!
