Bitdefender Antivirus users say on Google Play
Used the paid version a long time ago (have a review from 2015). Realized along the way that you really don't need paid AV. I certainly don't anyway. Don't need all the extra features either. Probably don't even need AV on my phone but it's free, it's Bitdefender, and there's not much reason not to. BitDefender has been audited and tested and it's one of the best out there with like a 98% detection rate last time I looked. Never had an infection on my phone or PC but again, doesn't hurt to have.
it was fast and no bull. now the test.
good
Recently the computer version bitdefender had a massive glitch and broken, it flagged and quarantined all kinds of hkey_users type of.. files? registries? as Act4.Detection, all legit ones, apps, installers, some random Microsoft stuff, vcredist, games, and all other random stuff, basically everything I guess. It's hard to tell which is safe or not safe and what's going on. Searched the net and it seems like I'm not the only one.
It didn't work on my old Galaxy tab 4
