Quick heal antivirus is one of the best antivirus for all kind of PCs but worst for android. It works good with PC does all the jobs in PC but when it comes to android it fails. It works properly with scanning the internal and external memory but it’s bit complicated to use to it couse setting ur privacy and passwords and all at least Avast works bit easier then it. When u want to install from a website not from play store with product key of that game it showes that is application can harm your device and not even allow u to install it in your device. That’s irritate me too much and when u download free addition only you get scan feature and block and anti thief feature and for some feature u have to spend money that means you will give extra charge for some feature. That frustrate me too much at least other antivirus comes with all the feature.
