i agree that pornhub is a cleaner pornsite but I've even got this message when visiting pornhub. the reason being is pornhub is a clean pornsite within itself but it is affiliated with a lot of other pornsites some good some bad. what i would like to know from these security programs, carriers like sprint, metro pcs, at&t, etc is; just who is responsible for sending these messages. . when i first received one of those messages (and in the interim you will get different messages from whoever is sending them some say u have 4 viruses some say 10 and i even had one to say i had 28)to me this sound like some convoluted marketing practices because as i said i clicked on 1 and it redirected me to google play to download either a cleaner or a antivirus. and wheater they are viruses or malware or merely popups remains to be seen. because I've had some that if u simply erase or clean your browsing history will stop them but only temp. but then there are some more tenacious than others for they are hard to get rid of and can have dire consequences on your phone and its settings. i think from the reality point of view that most of us even gov like fcc don't want to admit to and that is, as for the internet we have created a monster that have gotten to big to control. and most of this stuff is coming from big company apps that we install that want to know all of this personal stuff about you before they let u download their app. then they hit u with the biggest lie saying "oh we care about your privacy and we will not sell or give your email address or otber personal data to a third party" fuey! as soon as u're off their site and downloaded their app they'll give your information to any and everyone.this my friends is the price we pay for networking. and last i don't see any improvement or ways to control messages like these until the gov and companies like microsoft ,google, etc find and do the seemly impossible and that is to find someway of controlling what can be said or did via the internet. and back to those messages saying u have viruses on your phone which you don't then trying to sell u a bill of goods such as cleabers and antiviruses isn't that the same as false advertising
