that kind of stuff pops up all the time-ones that say you are being spied on, ones that say facebook friends have 'un-friended' you...it is all (internet garbage) don't ever click on anything like that at the top of a page...if someone actually un-friended you or something else ligit you would be contacted through (proper chanels) - a personal message or email---not some scam pop-up....some other's that sometimes appear...'someone has checked your credit score' or there has been a change to your credit score...'paypal has suspended your account'; ....there are actually hundreds of them out there---never ever click on something like that--if you see an (ad) that actually get's your attention-you want to check it out---don't click on it---write down the link address & go to it on your own...if a facebook message pops up-don't click on it- go to your actual facebook page & check it---be safe/not sorry...those ad's are just that- just like buying x-ray glasses from a comic book....
