Smartphones store sensitive information and users often hesitate to use antivirus software due to performance, storage, or subscription concerns. Effective strategies to protect devices from malware without third-party antivirus include: 1. Keep your phone updated with the latest operating system and app updates. 2. Download apps only from trusted sources like official app stores. 3. Manage app permissions by reviewing and denying unnecessary access. 4. Avoid clicking suspicious links in emails, messages, or social media. 5. Use strong passwords and biometric authentication. 6. Enable built-in security features like Google Play Protect for Android and sandboxing for iOS. 7. Avoid using public Wi-Fi for sensitive activities; consider using a VPN if necessary. 8. Regularly back up your data to prevent loss from malware infections.

URLCheck is an open-source application for Android that enhances link management by intercepting links before they are followed, allowing users to view, modify, or disregard them. It integrates with the VirusTotal API for threat checking, although users must sign up to use this feature. The app removes tracking tags and unnecessary redirects when sharing links. To set up URLCheck, users need to download it, select it as the default browser, and enable preferred modules. While URLCheck improves security, it does not guarantee complete safety online and requires users to exercise caution. The app only intercepts links from applications that redirect to a browser, and users must use the share menu to check URLs within their browser.
