Bitdefender. Choose What The Experts Use.

You get the most innovative technologies that predict, prevent, detect and remediate even the latest cyber-threats, anywhere in the world.

Best antivirus protection for Windows

Bitdefender Antivirus Plus packs the next-gen cybersecurity that won the “Product of the Year” award from AV-Comparatives. It protects Windows PCs against all online threats, and includes privacy tools such as Bitdefender VPN and Bitdefender Safepay.


Bitdefender`s unbeatable multi-layered protection keeps your devices safe from all new and existing online threats.

Complete Real-Time Data Protection [$IMPROVED$]

Absolute power in the best antivirus solution available today. Bitdefender Antivirus Plus works against all e-threats, from viruses, worms and Trojans, to ransomware, zero-day exploits, rootkits and spyware. Your data and privacy are safe.

Network Threat Prevention

Bitdefender Antivirus Plus stops attacks before they even begin. The new cyber threat intelligence technologies included can analyze and identify suspicious network-level activities, and block sophisticated exploits, malware and botnet-related URLs, and brute force attacks.

Advanced Threat Defense

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

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 attacks. It works with the Advanced Threat Defense module to protect your most important files from encryption by ransomware.

Vulnerability Assessment [$IMPROVED$]

Scan for security holes and vulnerabilities with just one click. Bitdefender Antivirus Plus checks your PC for outdated and vulnerable software, missing Windows security patches and potentially unsafe system settings, then indicates the best fix.


Online scams are on the rise, but our advanced anti-phishing protection easily keeps you out of danger. Bitdefender Antivirus Plus sniffs and blocks websites that masquerade as trustworthy in order to steal financial data such as passwords or credit card numbers.


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

Rescue Environment

Some sophisticated malware, like rootkits, need to be removed before Windows starts. When Bitdefender Antivirus Plus detects such threats, it reboots the computer in Rescue Environment for clean-up and restoration.


Bitdefender Antivirus Plus reacts instantly to e-threats with no compromise to your system’s performance.


Bitdefender Autopilot is designed to act as a Security Advisor and give you deeper insights into your security posture. Its smart capabilities mean that it can recommend security actions in the context of your system needs and usage patterns.

Bitdefender Photon™

This innovative, exclusive technology helps Bitdefender Antivirus Plus adapt to your system’s hardware and software configuration to save computing resources and improve speed and performance.

Global Protective Network

Most 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 are always completely private: Bitdefender does not scan the actual contents of your files, and never uploads or stores them in the cloud.

Game, Movie and Work Modes

Bitdefender Antivirus Plus detects when you play, work or watch a movie, so it knows not to bother you with unnecessary requests. Depending on what you are doing, Bitdefender temporarily halts pop-ups, adjusts visual settings, and pauses unimportant background activities so you can 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 and Bluetooth connectivity.


Bitdefender Antivirus Plus takes care of your online privacy and personal information.

Bitdefender VPN [$Improved$]

With Bitdefender VPN, you can stop worrying about privacy on the web. It protects your online presence by encrypting all Internet traffic. Bitdefender Antivirus Plus includes up to 200 MB per day of encrypted traffic for your Windows devices.


The Anti-tracker extension blocks trackers that collect your data and allows you to view and manage this information on each website you visit. It keeps your browsing data private and enhances performance by loading webpages faster.

Safe Online Banking

Bank and shop from a unique, dedicated browser that secures your transactions to prevent fraud. Bitdefender Safepay can now also automatically fill out credit card details in billing fields.

Wi-Fi Security Advisor

Assess the security of your Wi-Fi network and router, no matter where you connect.

Social Network Protection

Stay safe from malicious links and any online threats your friends unwittingly pass on to you via social networks.

File Shredder

Use this tool when you wish to delete a file for good and leave no traces that it ever existed on your PC.
