HELP I download movies on psa.wf which is reccomended on lemmy piracy sub . - sh.itjust.works

Today when i opened the tab of psa my firewall (rethink) pinged as i have set it to automatically block internet acess of newly installed apps and ask me to decide if i should allow them internet access. The thing is i can’t find them on my phones applist even if i enable system apps to delete it . Rethink shows it in installed catalog and i am pretty sure this is an installed app as i have gone through my system apps several times and just look at it it only tries to connect to that site and is made to pass as a system app . What should i do ? Should i wipe down my phone ? Also /c/ piracy should stop reccomending that shithole site honestly.
