To name a few,
avast, bitdefender, mcaffe, ... etc..
As the subject says. do they really provide enough security with transactions especially in crypto?
Smartphones are not secured,it can be encrypted to save the stored data on offline but your screen or other details can be takes from the third party apps which may not come under the category of virus so don't use smartphones for huge wallet fund storage unless you what all installed apps are trusted and not spying you.
