AC Question

This problem is 2-3 days old.I'm not getting how to solve this issue. An eye on suddenly pops up on any screen and when I click on it,an ad pops up. I don't know if my mobile is infected by some malicious software! I tried uninstalling my latest apps but despite of it..The issue is not solved. Please if you can suggest me any way for this issue coz it's becoming very irritating.
Factory resetting would be my last option.
See if you can help
Kind regards
