WELCOME TO ANDROID FORUMS Rir !
My guess,judging from the url's in your screenshots,you've been visiting sites that promise "free" versions of otherwise paid apps.
Stay away from these sites,they contain pirated (read:Stolen/etc..) versions of paid apps & insert things to hijack your phone & then do all sorts of nasty things on your device (Ransom ware/steal personal account data/etc...)
My recommendation:a factory reset & in the future,only get your d/l content from trustworthy sites.
