Zone Alarm is a mobile phone anti-virus application that protects its users from malware, ransomware, and wi-fi attacks. Smartphones are very prone to phishing or hacking attacks and viruses. Many people don't give the security of their cellular phone a second thought because smartphones are so convenient to store so much information. Hackers can rob you of your photos, videos, banking app login information, and take control of your microphone. Zone Alarm offers anti-phishing, safe-browsing, wi-fi network security, and anti-bot to protect your photos and documents. This app is not free, but you can try it out on a seven-day free trial.
