Don’t install an antivirus
I find it funny how one of the goals we have as writers of a blog dedicated to the android world is to talk about tricks for Android, so that users can find in the blog post with which to learn how to use their smartphone. But the truth is that afterwards I meet many users who, despite having very basic knowledge of Android, have an antivirus installed. What’s more, the less knowledge they have, the easier it is for them to have it installed, and in reality it is the opposite.
Why is an antivirus useless for a basic user?
There are users who do not know the difference between the Chats tab and the WhatsApp Contacts tab, but who have an antivirus installed because they do not know if they can inadvertently install a virus. No, you will not have any virus on your mobile. We are not going to say that it is completely impossible for the mobile phone to be infected by a virus, because it is not like that. But in your case, it is practically impossible. The operating systems themselves have their own security systems to prevent malware. To deactivate all these security systems you would have to do many things on your mobile. If we do not even know how to differentiate between the Chats tab and the Contacts tab of your WhatsApp, or you did not know that you can set several alarms on your Android, it is useless to think that you need an antivirus.
The antivirus will slow down your smartphone or tablet
In addition, you should not forget something, the antivirus will slow down your smartphone or your tablet. It’s going to be running quite frequently, which will consume battery as well as processor and RAM resources. This will make your smartphone and tablet perform worse, something you probably want to avoid. In fact, you may even have installed this antivirus because your smartphone or tablet has started to run slower. If so, the result will be completely the opposite.
Antivirus is also not useful for advanced users
If you are an advanced user, we do not even need to explain this to you, but we will explain it so that basic users end up being convinced that they do not have to install an antivirus. Advanced users can make modifications to their smartphones that could make it more vulnerable to malware. For example, they could have enabled the option to install applications that do not come from Google Play. They could have the mobile rooted, or they could have the bootloader unlocked. Suppose this is so. In other words, suppose that users have left the door open to malware on their smartphone. No antivirus application will have the ability to prevent malware from installing on mobile. For many reasons. It is the user himself who has disabled the security of his mobile. Malware is designed to hide itself and to be able to avoid these antiviruses, and even to deprive them of the ability to act as such. The antivirus will never recognize malware. And in many cases, the malware will affect the mobile in a way that the antivirus cannot. Let’s say that the antivirus is only an app, so it can only be activated against other apps, but not against malware that installs at a low level, and that comes from a firmware error, or because of the processor or something like that.
In an extreme case, the antivirus could even be responsible for installing viruses or malware on our mobile to make us believe that we need to switch to a payment method for the antivirus. This is not so normal, but this possibility has always been talked about, so it is something that we should not ignore either.
Antiviruses that seem trustworthy are useless and could even have some relevance in the operation of our mobile because they are running constantly, and there may even be antivirus that are viruses themselves.
That said, when you see a user who has an antivirus or something similar installed on their mobile or tablet, explain this to them. It’s useless, and it will only make your tablet or mobile perform worse. It should be the first Android hack any user would learn.
