To scan your phone for viruses in 2026, the process depends on your operating system. For Android, you should use the built-in Google Play Protect; open the Play Store, tap your profile icon, and select "Play Protect" to run a scan of all installed apps. You can also install reputable third-party antivirus apps like Bitdefender, Norton, or Avast for deeper file-system monitoring. For iPhone, Apple's closed ecosystem generally prevents traditional "viruses," so there is no "scanner" app. Instead, ensure your iOS is updated to the latest version to patch security holes, and check "Settings > Battery" for apps causing unusual drain. Regardless of the device, you should also look for "red flags" like excessive pop-up ads, unrecognized apps, or a sudden spike in data usage, and use a tool like Google's Security Checkup to ensure your accounts haven't been compromised.
