Could someone recommend the best free antivirus/cache cleaner for samsung phones

[missbee]

I've been using clean master for a while on my samsung galaxy a32 5g phone but only recently I keep getting notifications that it's not working and it's been put into a deep sleep mode. Can anyone recommend a decent free antivirus/cache app that works well. And can you please tell me how samsung knox works.

Thanks bernie.

Device care comes as standard to your device, you'll find it in your settings part of your phone, scans everyday automatically for malware and virus's.

Thankyou for the reply to my post.

@missbee Personally I do not think an Anti virus on Android is strictly necessary if  you do not go outside official sources, I am happy with the security  protection provided by Knox and McAfee Anti Virus is on Board should you wish to use it.  Think it can create problems if you have additional  Anti Virus software running with the MCAfee enabled. However opinions vary and you may wish to have a look at this thread.

Should be standard on your phone
Just type scan in your settings

Hi Bernie, I'm sure you don't need necessarily any of antivirus app. When you get software update then after always highly recommended clear cache partition that's it. Plus Samsung device care default app is really good.

Just on a side note... There are many anti virus or cleaning apps on the play store that don't even work and are just riddled with ad ware. More of a nuisance than helpful of effective. I've never had to use any anti virus personally.

I use the Samsung maintenance settings in the phone settings.
