Bitdefender Internet Security 2018 and the fuller-featured Total Security 2018 both earned high marks from third-party testing labs and performed better than other programs in our own detection and performance tests. Both excel at detecting and removing internet threats and they use few computer resources to do so. They both also comes with extra protection features, including parental controls and a personal firewall. For these reasons, Bitdefender Internet Security is our top pick for the best internet security software. Additionally, the higher priced Bitdefender Total Security 2018 is our top pick for premium internet security, as it includes more tools and safeguards (such as online backup storage and Android cell phone protection) than Bitdefender’s basic internet security program.

Performance

Bitdefender Autopilot™
Once switched on, Autopilot will run your entire cyber-security by itself. It makes optimal security decisions without asking for your input through nagging pop-ups and dialog boxes. Nothing to set up, nothing to configure.

Bitdefender Photon™
This innovative, exclusive technology helps Bitdefender Internet Security 2018 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 2018 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.
