Why do I need ZoneAlarm Anti-Ransomware, doesn't Antivirus protect me? Updated 2. Oktober 2017 11:12 Antivirus will protect in some cases of already known and cataloged Ransomware but will not protect you against new Ransomware and cannot restore any files Ransomware may have encrypted. The first hours and days of a new Ransomware attack are the most critical and most dangerous for your PC and your files. This is known as a Zero-Day attack. ZoneAlarm Anti-Ransomware is specifically designed to protect you from Zero-Day attacks of new Ransomware and can restore any files that have been encrypted by a Ransomware attack*. ZoneAlarm Anti-Ransomware is a necessity and will work along side your current security and antivirus software. To learn more details about ZoneAlarm Anti-Ransomware and Pricing Click Here.
