This widespread adoption has made Android a favorite target for cybercriminals. In just six months, more than 18.000 malicious apps were detected on Google Play, many of which contained classic malware, Trojans, spyware, and phishing tools.

Protecting your personal, work, and banking data is more urgent than ever.That's why, in this article, we'll guide you step by step through choosing, configuring, and getting the most out of the apps that really make a difference.
What are the main security threats on Android?
Before you rush into installing any security tool, it's a good idea to understand the real risks your Android smartphone faces:
- Malware and viruses: Malicious software that can steal information, display unwanted ads, or even hijack your device.
- Phishing: Scams that simulate trusted services to steal your passwords or other data.
- Spy apps: Programs that, without your permission, access your messages, location, camera, or microphone.
- Loss or theft of your mobile phone: At the risk of accessing all your stored information.
- Wi-Fi and insecure networks: Public connections that can be easily intercepted.
- Downloads from unofficial sources: Very often disguised as pirated Premium versions, they often come with malware.
- Excessive permissions: Apps that demand access to everything (contacts, SMS, location, etc.) without justification, opening the door to data leaks.
In addition, according to statistics from AV-Test and other independent entities, a large portion of malware continues to enter through official stores or due to a lack of permission checks. Therefore, being careful about what you install and how you do it is vital.
What features should a good Android security app have?
With so many alternatives, it's easy to get lost. Before installing any security app, keep these keys clear to choose only the best:
- Specific and clear functions: Better a few well-executed features than overly invasive or ad-laden multipurpose solutions.
- Justified permissions: A security app should only request the permissions necessary to function, not all of the phone's permissions.
- Regular updates: If an application doesn't receive improvements within 3-6 months, it's bad news: threats evolve every week.
- External audits and proven reputation: Give priority to apps developed by recognized companies, open source projects, or those audited by third parties.
- Cross-platform compatibility: If you can protect Android, iOS, and, if it's a password manager or VPN, your desktop too, all the better.
- Zero intrusive ads: An antivirus with banners, mini-games, or aggressive pop-ups is not a good choice.
Remember, digital security starts with using responsible apps, keeping your operating system up to date, and never disabling native protection features.
