I am getting a ad site that is blocked by my antivirus itself not an adware program or script. It is coming up cdn.onesignal.com. I know this is a mobile push site. If my actual antivirus is flagging it as non-trustworthy than that is something to look at. It could have just been reported by a lot of people an be a false positive, got my doubts though. I am using Malwarebytes an they are actually really good at flagging and removing bad content.
