Main Features Explained
Real-Time Data Protection
This feature continuously scans files, downloads, applications, and system processes for malicious activity. It helps stop threats before they can infect your PC, making daily browsing and software installation safer.
 
Ransomware Remediation
Bitdefender Internet Security monitors suspicious encryption behavior and can automatically restore affected files if a ransomware attack is detected. This adds an important layer of protection for personal documents and work files.

The integrated firewall helps manage network connections and blocks suspicious communication attempts. This is especially valuable for users connected to public Wi-Fi or shared home networks.
