No you do not need antivirus and stay away from anything on the play Store that's like a CC cleaner cache cleaner and so on it's all junk. Send me your email address and I will upload a program for you that you can use that keeps you free from your IP address and so forth but you do not need antivirus on the phone because it has Knox. I have had 30 40 brand new phones and I have never use antivirus and I have never ever got a virus or malware.

I totally agree with you I have had every Android phone since the birth of Android I have been an IT tech for over 30 years and never if I got a virus on my phone. Throughout the years I have rooted many phones and used side loaded apps. Fortunately Google® has made phones very customized where you don't need to root. In my opioono anti virus apps are resource hogs as well as battery drainers. I run two phones , one being Note 9 and the other Google pixel 3 XL. Both phones are amazing and I stress ...I have never had a virus and I have never been hijacked by ads. One thing I STRONGLY recommend is ADGUARD... By paying for it. Do not search for a patched version. I use the nightly update version and have about 98% no ads or multiple tabs opening. Again, go to www.adguard.com. Don't be cheap and get a hacked copy if you do you would have to uninstall every version before you do an update. It is a green icon in the shaped like a shield. Hope this helps!
