If your phone is running slowly, overheating, or displaying suspicious ads, it could be a sign that it’s infected with viruses or other types of malware. Fortunately, there are free and effective apps available on the Google Play Store and the App Store that can help you detect and remove these threats. Below are five great options that are free to download and offer advanced security and cleaning features to protect your device.

Avast Antivirus & Security

Avast Antivirus & Security is one of the most popular apps when it comes to virus and malware protection. Available for Android and iOS, the app offers comprehensive real-time protection and additional privacy and system optimization tools.

It automatically detects malicious apps, dangerous files, and suspicious links, preventing users from falling for common scams. Avast also has a smart scanning feature that analyzes the behavior of installed apps, providing an extra layer of security.

It also offers spam call blocking, phishing protection, and even a free VPN with a daily limit to help secure your connection on public Wi-Fi networks. Its interface is clear, well-organized, and easy to use, making it ideal even for those who aren’t very tech-savvy.

AVG Antivirus

Another big name in the fight against viruses on cell phones is AVG Antivirus. Developed by the same company responsible for Avast, AVG stands out for its lightness and efficiency in detecting threats. It performs automatic and manual scans in real time, ensuring that any suspicious app or file is immediately identified and eliminated.

One of AVG’s biggest advantages is its “Anti-Theft” feature, which allows you to locate, block and even erase your phone’s data remotely in case of loss or theft. The app also protects personal photos and documents with an encrypted vault.

The user experience is fluid, with clear alerts and optimization features that help improve device performance, such as clearing cache, temporary files, and RAM. It's a solid option for those looking for security and practicality in a single app.

Norton 360

Norton 360 goes beyond simple virus removal. It offers a complete digital security suite for your mobile phone. With protection against malware, spyware, adware and other cyber threats, the app ensures that your smartphone is always protected in real time.

In addition to virus detection, Norton 360 monitors Wi-Fi networks, alerting you to insecure connections that could compromise your data. Another interesting feature is the “App Advisor”, which analyzes apps from the Play Store before they are even downloaded, informing you whether they are safe.

For those concerned about privacy, the app offers tools to block online trackers, as well as a secure and unlimited VPN. The look is modern and navigation is very intuitive, making it easy to access all features even for beginners.

Bitdefender Mobile Security

Bitdefender Mobile Security is a lightweight and powerful solution that stands out for its accuracy in detecting malware. The application performs fast and efficient scans without impacting the phone's performance. It works in the background and keeps the system protected 24 hours a day.

A unique feature is “Autopilot,” which acts as a personal security assistant, recommending actions based on device usage. The app also has account security checks (to see if your email has been compromised in a breach) and protection against fraudulent websites.

Its clean interface, combined with the reliability of the Bitdefender detection engine — one of the best on the market — makes the application a sure choice for those looking for hassle-free protection.

Malwarebytes Mobile Security

Malwarebytes is a respected name in the cybersecurity world, known for its effectiveness in identifying and eliminating even the most complex malware. The mobile version follows suit, offering a deep scan that detects Trojans, adware, ransomware, and other types of hidden threats.

The app also blocks malicious links while browsing the internet and checks abusive app permissions, helping the user maintain full control over their privacy.
