If you download it would Google Play Protect detects it as a fake?
Good question and I haven't tried. Mainly because I would hate to get something on my phone that I wouldn't want. I can still try check this app out a bit deeper elsewhere. I'll get back with the results asap.
Update.
Just wanna start by saying even this " developers " linked site screams fake/scam and using other companies/vendors names could also be a serious copyright infringement. People here on MT that maybe is active on Adguards forum/site could report this directly to Adguard, as I would guess that is a much faster/better approach.
@HarborFront , personal I have not found any specific fast way to test this app with Google Play Protect, other then...
