In one of our discussions about cyber security, a school of thought that discouraged the use of antivirus on Android device emerged. They are of the opinion that Android phones cannot really be attacked and therefore the use of antivirus does more harm than good.
In truth, antivirus does a lot of harm to Android devices. Antivirus increases the workload of the phone thereby increasing power consumption and the temperature of the device. Even when the phone is not in use, antivirus is working thus doing many of the things malware does.
Considering that antivirus drains the phone’s battery – the same thing virus does, and it uses a lot of phone’s memory, do you think it’s still proper to install it? Can your phone be hacked in the first place?
Can your phone be hacked?
To answer this question, let us first know the meaning of hacking. Hacking generally refers to unauthorized intrusion into a device or a network. A hacker can have control over, or manipulate, a system by means of computer programs or applications.
Based on the above, Android devices could be hacked. In fact, hacking Android devices has become popular and easier than ever before. How do you know that your phone has been hacked?
1. Your phone battery start draining rapidly. This is because, some programs have been introduced into your device and they run on the background.
2. Your phone’s temperature becomes unusually high.
3. You start seeing unusua pop-ups.
4. Some of your applications may start misbehaving. Sometimes they will refuse to launch, sometimes they will crash.
5. You start seeing applications you never installed.
6. Your data drains unusually fast.
When you start seeing these signs, your phone might have been infected.
Should you install antivirus?
Yes and no. Yes if you cannot manually protect your phone against malware attack. No if you can.
The easiest way to get rid of your phone from virus is to restore it to factory setting. This method is expensive because each time you do it, you’ll have to download new applications and update existing ones, that can be data intensive especially if you don’t have reliable Wi-Fi.
Manually deleting suspected applications from your phone is a good method of safety.
How to prevent your phone from being hacked
1. Always download your applications from trusted sites like Google play store.
2. Be wary of links no matter who sent it.
3. Manually type websites in the address bar.
4. Restore your phone to factory settings from time to time.
5. Do not use untrusted WiFi connection.
6. Use VPN if you must use public WiFi
7. Be wary of charging stations. Don’t plug your phone into any USB cord you see.
8. Turn of your Bluetooth when not in use.
9. Do not leave your phone unattended in public.
10. Use good password, pin or pattern to lock your phones.
