Yes and no.
Only use reputable and well-known developers, for example, Bitdefender, Kaspersky, Dr. Web.
Just to clarify, I voted Yes for the poll question (Does an Android device need an Antivirus app?).Yes and no.
Yes, I am beginning to dislike Avast (& poor AVG), more and more. They have already ruined CCleaner (Android), which is identical to their own crADp app, and soon will destroy CCleaner (Windows/Mac) by pushing their other Avast services; VPN, Anti-Track Premium etc. into the existing CCleaner userbase. Hundreds of millions of Windows/Android/Mac users will be using Avast products. $$$.I would also avoid AVs with performance/battery optimizers, cleaners etc, and those full of ads (rules Avast out for me).
Which Bitdefender app did you use (Free or Paid)? What was the Battery and CPU usage like? What Android / SoC?Unfortunately for me Bitdefender was anything but light. If it has to be free I would suggest either the super-light ESET, or if you want web protection and automatic updates, the slightly heavier Sophos Mobile Security - fully featured and with no ads, and way lighter for me than Avast and even Bitdefender

In my opinion, no. Basically, if you're just downloading trusted apps from the Play Store, read reviews and permissions, you shouldn't have any problems with malware.
