Virus is a word that, when said, already brings great concern. On a computer, viruses are capable of doing countless things, including even ruining it. Like any operating system, mobile devices are also no exception to this plague called viruses.
But what many people don't know is that there is a huge difference between a computer virus and a cell phone virus, for example on Android. On a computer, you don't need to install anything for it to start running, so viruses start running automatically and you need an antivirus. But how does it work on a cell phone?
How does a virus on Android work?
On Android, the virus works very differently. The system has a form of security that inhibits this. Anything that takes data, makes changes, and other things, needs to be installed on the Smartphone and still needs to receive the necessary permissions. So what does this mean?
Isso diz que para se ter um vírus no Android é preciso instalar um aplicativo com vírus e ainda fornecer permissões pra eles que muitas vezes exigem permissões root, se você baixa aplicativos apenas da Play Store o risco de se ter um vírus é nulo, se você baixa apks da internet o risco sobe um pouco mas ainda sim é quase zero, basta que tenha uma certa atenção e baixe de locais confiáveis.
So you can relax and visit any website you want, you are free from any risk of a virus. If you see ads saying that your phone has a virus or is infected, don't worry, they are just ads to get you to download other apps, most of which, when you click on them, take you to the Play Store, and many of them to download antiviruses, kind of ironic, right?
What is the best antivirus for Android? Should I have one installed or not?
Well, the best antivirus for Android is you, there is no need to have an antivirus on Android if you only download apps from the Play Store, even if you download them from outside, there is also no need if you are sure that it is trustworthy.
Should you have an antivirus installed? Honestly, the answer is no, these applications are very heavy, and besides running in the background, they also cause problems.themem too much ram memory causing crashes and slowness in Smartphones.
“Ah, but the antivirus has a great optimizer function, and it also cleans the memory!” Well, there is a method for cleaning that the cell phone memory through the cache very simple. And if you don't have the option, you can still use a lightweight program that does all this function and also cleans applications that run in the background, Ccleaner, which you can download at the end of the post.
But remember, if you have installed a strange application and you are suspicious, uninstall it or download an antivirus and check if everything is ok with that app.
