For the last 3 months quite a few of my users, who are using Android mobile phones(And one Motorala user), are reporting that the ads on my site often open as phishing popups saying their phone has been infected by a virus.
I only use Google Adsense on my site, and the URL which opens on the users' phones is no in the ad library, so I can't block it. I have tried scanning my WordPress installation to see if it has been infected, but the scan showed up clean.
I can't reproduce it as I have an iPhone, and using an emulator like BlueStacks didn't reproduce it either.
I honestly have no idea what to do. My users are getting more and more frustrated. Have any of you experienced something similar or do you have any suggestions on how to find a solution?
