Possible virus

[Fieldy]

Hello I'm new to this so please bare with me!! I recently bought an Xperia z2 off ebay as the previous owner (had the phone a couple of days,receipt shown as proof) preferred windows phones. Anyway I keep getting this pop up telling me to upgrade my protection and O click install which I haven't done (obviously a virus) I have since upgraded the avg protection to pro but don't know how to stop this thing popping up! Pop ups are disabled and this thing comes up whenever I go on yahoo mail,Facebook or generally when it feels like it! I'd appreciate some help please, thank you!

Might be something from a browser or an app. Really not sure, but if you say safe mode helped, I would try to uninstall apps.

@Fieldy Why not a give a try with factory re-set

[Fieldy]

Sorry I managed to somehow lock myself out what a fringing palava!! Anyway it's still happening so I guess my next option is a reset....thank you all for your time and help

@Fieldy You should perform a software repair instead.

No problem. If you need a guide, here is how to do a software repair using PC Companion.
