Before telephones and satellites came into existence, encoded messages were sent across oceans only with dots and dashes, known as Morse Code. This encrypted language was invented in the 1800s to send secret messages during war emergencies, the most advanced code of its time. Only people who understood Morse code could understand those messages. But even at the time, some codebreakers who could decipher these signals, and the messages would end up reaching the enemy ground.
Today, we use our smartphones for everything, including banking, shopping, messaging, and storing memories. Just like Morse code, even smartphone messages, OTPs, banking details, social media chats, and video calls are encrypted, but there are codebreakers trying to steal your secrets. Hackers have become the new codebreakers, and instead of listening for beeps on radio, they are directly sneaking into our phones with hi-tech malware and viruses.
This demands safer device security standards and secure antivirus apps for Android, which can spot these hidden threats and keep our phones safe. Let’s discuss why you need an Antivirus and the right antivirus app defense for your Android device.
Why Do You Need an Android Antivirus Software in 2025?
If you don’t need an Antivirus app or software on your Android device, think again. The following section explains why Antivirus is not a choice but a necessity.
- Android, the Easiest Target:
Since Android is the most used open-source operating system globally, hackers and scammers try to attack these devices more often as they can do it more easily. As more people use Android these days, harmful apps can spread viruses and malware easily across devices.
- Only Computers get infected. No:
Android phones can become infected with various types of malware, such as spyware, ransomware, and Trojans. These can steal your photos, messages, or even money from your bank app without your knowledge.
When you download apps from the Google Play Store, Google does a safety check of apps for viruses, and you are safe from virus attacks. But downloading apps from other sources or allowing other apps and websites to install apps can be risky. Antivirus apps scan these apps and warn you if something is wrong.
- Built-in protection – Good not perfect:
Android has built-in safety features, Google Play Protect is one of them. It checks harmful apps with abnormal behavior. However, these tools can sometimes miss new threats. Antivirus apps add an extra shield, especially, if you use your phone for online banking, shopping, payments or other work.
Many antivirus apps do more than just neutralize viruses. They can help you find your phone if it gets lost, block spam calls or texts, and even make your phone run smoother by cleaning up junk files.
If you use public Wi-Fi, download files from unknown sources, or store sensitive information on your phone, you might face more danger. In such cases, Antivirus apps protect you by watching for threats in real-time and can stop problems before they start.
- I don’t need an antivirus:
If you use the Play Store, avoid risky websites, and keep your phone OS updated, the built-in protection may be enough. No, you are wrong, everyone wants extra peace of mind when they do more on their phone, and having an antivirus app is not just a smart choice but a necessity.
- Hackers are always finding new tricks:
Cyber threats are always changing and no matter how cautious you are, cybercriminals are always a step ahead. Antivirus apps are updated to neutralize the latest threats, so your phone stays protected even as new dangers appear.
Antivirus app enhances your Android device protection and also come with utilitarian features. So, if you want an extra layer of safety, get an Antivirus app for your device.
