Happened to me several times but the good thing is is I noticed how small the app was and was able to do the same thing you did just recently got Bamboozled though I installed an app on my phone and it had a side app in it and it was pushing all kind of ads left and right I mean I have my ad blocker on so I wouldn't see a blank page when they have popped up but I can get it to stop my ad blocker couldn't stop it so I had to install an app from Google which is called ESET it's a paid app but it is definitely worth it you should look it up I was able I couldn't find what what happened was I could not find the file anywhere to delete it but what happened when I installed this app if found all three files just like that great antivirus app ;-)
