Malvertising/Scareware on Wattpad

So i was scrolling through Wattpad like usual to see any fanfic i was reading got any update and suddenly without clicking anything i got redirected McAfee Online Monitor, since it clearly a scareware i immediately click off it and and deleted any cookie related to it.

It my first time experience the issue on Wattpad so i deleted my entire search history include all the cookie and have to run through all the procedure like running tron script to see if my computer got hit by virus or malware but it come up clean.

I also have adblock and the offical McAfee WebAdvisor extension on my brower but after turning of the McAfee even deleting it afterword the problem still persists, so i think the problem is with the website itself and how the malvertising manage to get through if so then how long does it take for Wattpad support to fix the issue.
