Take a Look Inside

Protection

Complete Real-Time Data Protection

Absolute power in the most efficient anti-malware solution available today. Bitdefender Internet Security 2019 works against all e-threats – from viruses, worms and Trojans, to ransomware, zero-day exploits, rootkits and spyware. Your data and privacy are safe.

Advanced Threat Defense

Bitdefender Internet Security uses a technique called behavioral detection to closely monitor active apps. The moment it detects anything suspicious, it takes instant action to prevent infections.

Web Attack Prevention

Our web filtering technology ensures that you never land on a harmful website. Find out whether your search results are safe to access before you actually click on a link. Bitdefender Internet Security also blocks all known infected links.

Multi-Layer Ransomware Protection

Bitdefender’s multi-layered approach against ransomware includes a data-protection layer that safeguards your documents, pictures, videos, and music against any kind of ransomware attack. In conjunction with the Advanced Threat Defense module, it protects your most important files from encryption by ransomware.

Anti-Phishing

Bitdefender Internet Security sniffs and blocks websites that masquerade as trustworthy in order to steal financial data such as passwords or credit card numbers.

Anti-fraud

Our advanced filtering system warns you whenever you visit websites that may try to scam you.

Safe Files

With Bitdefender Safe Files you can prevent unauthorized changes to your most important files. You simply add folders to the watch list, and Bitdefender guards the files stored in them against ransomware and other types of malware. Only applications that you explicitly trust are allowed access to your Safe Files.

Rescue Mode

Some sophisticated viruses, like rootkits, need to be removed before Windows starts. When Bitdefender Internet Security detects such threats, it reboots the computer in Rescue Mode for clean-up and restoration.

Performance

Bitdefender Photon™

This innovative, exclusive technology helps Bitdefender Internet Security adapt to the hardware and software configuration of your system in order to save computing resources and improve speed and performance.

Global Protective Network

Most of the heavy scanning takes place in the cloud, so there is virtually zero impact on your local resources. This means your system’s speed and performance remain unaffected. And your files always remain completely private: we do not scan the actual contents of your files, and we never upload or store them in the cloud.

Game, Movie and Work Modes

Bitdefender Internet Security detects when you play, work or watch a movie, so it knows not to bother you with unnecessary requests. This way, you can focus on what’s important. Depending on what you choose to do on your computer, Bitdefender temporarily halts pop-ups, adjusts visual settings, and pauses unimportant background activities to allow you to enjoy your device to the max.

Battery Mode

This useful, intelligent feature saves battery life for laptops and tablets by temporarily tweaking system settings such as display, system cooling, system updates or Bluetooth connectivity.
