Is the anti-virus on an Android phone really necessary? Will such a program actually provide us with security in the network? Or is it just a waste of valuable resources of your smartphone or tablet?

Mobile devices, mobile Internet – this is our everyday life. In its "area" you can also notice the activity of "uninvited guests" – viruses. Those that are supposed to "work out" computers are different from viruses created for Android. Is therefore the basic protection against mobile hacker activity, installing an anti-virus ? Here the sentences are divided. One thing – in terms of counteracting the destructive influence of viruses on all devices connected to the Internet – remains unchanged: rationality in using them, regardless of whether it is a computer or a smartphone. It is worth paying attention to the nature of viruses created for computers and mobile devices – while in the case of the former the hardware and viruses are the most likely to damage it, in the case of mobile devices, the most important data for users are hackers . Is the first or second threat greater? Here sentences can also be divided. For sure you should do everything not to become an easy target for potential cybercriminals.

Is it worth installing anti-viruses on devices supported by Android?

There are definitely more votes on "no". Everything depends on how we use a smartphone or tablet. If we often decide to download applications from unknown sources (which, by the way, it is difficult to consider rational operation to a minimum extent and is never recommended), it may be worth installing an antivirus. Let us not, however, think that such a program will capture all threats.

Still the best way to not give hackers a chance is to download the application only from the Google Play store . Although in this case we do not have a 100% guarantee that we will not "virus" the smartphone, however, verification of applications provided by Google Play is potentially one of the most insightful and reliable. Against the download of antivirus software for mobile devices will also be those who claim that there is currently no greater "chance" for any virus to paralyze Android, and the antivirus will only unnecessarily burden, and thus, slow down the device. This is somewhat true, but let us once again remind that the purpose of most malicious applications created for Android is not the system itself, nor the device, but the confidential information about the user . Therefore, many people, even for the "slightly slower" work of the device, decide to install an anti-virus. However, we must be aware that for now, anti-virus "on mobile" are not as effective as those whose task is to protect the computer . Performance tests performed by research teams have proved that the sensitivity of "mobile" anti-viruses to cyber attacks is highly unsatisfactory. Will antivirus vendors, over time, invest more money to develop these programs? Time will tell. If we think that even the smallest additional security makes sense – we will definitely install an anti-virus on Android. Others will only bet on their own caution, not wanting to reduce equipment efficiency. In addition to not downloading applications of unknown origin, the second key condition for effective anti-virus protection for Android devices is to look carefully at the applications in terms of the permissions they require during installation. If there are too many of them suspiciously (especially with a simple application), we should finish the process of installing such a program as soon as possible. In this context, we should also pay attention to the Administrator's rights . If too much data is made available, then remote control of the mobile device may be acquired.

Simple and paradoxical – more dangerous? The characteristics of viruses on Android

This is a kind of paradox. Viruses "on" computers are more complicated than malicious applications for mobile devices, but the former are definitely more often detected by anti-viruses.

"Mobile" viruses are not malware threats, but de facto, ordinary applications that are "packed" with different permissions – but it is nothing else but an installed file that is relatively easy to get rid of . Usually, these are not complicated threats that could be found in the system (files or in the kernel). So why are there many attacks on sensitive data that such an application can find even in the post office, social media, and even in video files or in the photos on the smartphone? In addition to the lack of elementary caution in installing such applications , the problem may also be the nature of their operation, even if the number of required permissions did not seem too large and we decided to install the application, which turned out to be dangerous, the attack can take place … asymptomatically. The question – whether to install an anti-virus on Android or not – remains therefore open and depends on what the user puts emphasis on and on what level of threat is prepared. If we often download various applications, we do not always carefully examine the permissions that accompany them, maybe the installed anti-virus will give us a bit more chances for data protection, but we can not – for now – count on the optimal protection from this site.
