Malware are known as the codes, applications or malignant services that cause failures in computer systems; its acronym means “malicious software”. The objective of malicious software is to damage, and to seep in, having specific tasks to reduce a computer systems’ performance; or, in many occasions, information theft. Malware embraces all sorts of computer viruses that we know as; worms, Trojans, spyware, amongst others. Lots of these viruses are created for a specific task. It’s called malicious software because it’s a problematic software (bugs) but in an organized way, and with the intention of damaging other systems or services.
There’s a way to defeat these computer viruses; the most commonly used are antivirus programs or anti-malware to deeply analyze the whole storage, processes and services of our computer to erase them or just to find where the problem is. However, a malware is software that is specially designed to be invisible against these antivirus programs, anti-malware, or the seeking of any file within folders. While the intention of these viruses is to grow and spread within our phones, antivirus programs are becoming stronger; finding and detecting any sort of virus threat before it acts by itself. Lots of these antivirus programs recognize specific viruses because their makers also created their antidote; its’ antivirus.
Malware in smartphones
Any malicious software can be dressed up in different ways in order to be invisible to the users’ eyes. Even a simple publicity could be a virus which can infect our system just by a touch of the screen. It’s really important to consider that not every internet advertisement is true. One of the most common ones is when we get into any web page and a short advertisement, about our smartphone model displaying an error that could be solved if we download the application advertised. It is totally false and that’s when this malicious software dressed up as advertisement seeps into our smartphone and infects it.
We’ll be able to see immediately if our smartphone has been infected by any malicious software; high battery consumption, and very low performance of the phone are signals that we can use to identify this. This type of problem is commonly caused by installing applications, but if you see that after downloading an application these types of problems begin to occur; you will have to do something more than just uninstalling the application because it’ll be recorded on the virus log. In order to deal with this situation, we should search for an application that works as an antivirus, or we can reinstall the standard firmware.
Europe and the rest of the world want to carry out various tasks to prevent malicious softwares from being downloaded into our smartphones. One of those interested in this campaign is the police and the civil guard in Europe (Europol) who have initiated awareness among smartphone users to take maximum caution when installing any application that could contain malware since we have on our phones information such as our identities. Given that, it is guaranteed that if in our smartphones we have useful information, such as; IDs, bank or personal information, it can be stolen and used whichever way the malware wants. Usually, malware steals previous logs, bank accounts and personal information.
The way in which these campaigns should be taken is that we have to make sure we don’t install any application outside of the app stores, such as; Google Play Store or Apple Store. Many applications that aren’t in these stores are independent, and that’s why they have not been tested by a developer like Google or Apple before their launch. Some developers lack money to launch their applications in app stores. Whatever the case may be, we have to be careful about installing applications from unknown sources
How to avoid it or detect it?
Many antivirus programs were developed on mobile platforms to recognize and detect when they’re being attacked or infected by malware. The best recommendation is to avoid unknown and unreliable sources. We have to take note of where and when we are downloading an application from, and we have to read the applications’ permissions before installing. Here, we’ll find useful and detailed information about permissions required in order for applications to work.
One recommended application that currently analyzes most of our smartphone areas or sectors when they’re infected is Bluebox Security Scanner. An application pretty simple for Android which searches 3 of the most infected areas affected by malware; data application analysis, unknown application sources and the security patch. This application guarantees that your security patches are updated in order to better recognize and analyze an application package and search out malicious codes.
