Pop Up Ad "FBI"
About an hour ago I got a pop-up scroll ad that said my phone has been blocked and to give my card. I immediately turned of my wifi, closed safari, brought it up without access to the internet via wifi, and then closed the webpage that the ad contained. I looked it up and found out it was malware. I went ahead and took my email account of my phone, cleared the browsing history, and then restarted my phone. I got worried so I backed my phone up to my computer and then reset my phone and reloaded my stuff back. Is my phone clean after doing all that? I heard that this type of ad can take control of the phone, can it do this after everything I did?
