Hi there. Several times I have gotten a popup message on my ipad from comcast constant guard saying one or more of my computers is infected with a bot and it invites me to visit comcast to learn more about malicious software. I have opened pdf files in the past but my ipad is certainly not jailbroken. Is there a way I can verify that there is a problem? And if there isn't a problem does anyone know why I would get this popup? Thanks so much!
