Powerful anti-ransomware

5 billion USD was lost globally because of ransomware alone in the last year. Internet Security keeps you safe.

  • Blocks all attempts to hijack your data and hold it to ransom
  • Protects your precious files, photos, and movies
  • Even recognizes previously unknown mutation

Automatic web protection

1.7 million web attacks are detected every day! Surfing, shopping, banking, updating social media… Internet Security offers real-time protection against malware, viruses, phishing, and more.

  • Won’t slow your system down
  • Repairs files too

Secure password management

Keep your online accounts safe:

  • Generates and securely stores strong, unique passwords
  • Logs you in automatically if you choose
  • Remember only 1 unique master password
  • Synchronizes passwords & account details across all your devices

Real time security alerts

Scans your accounts and alerts you if there’s any risk to any of your accounts.

  • Alerts you if your account was breached
  • Notifies you if a website, where your passwords are stored, is infected
  • Identifies weak passwords across all your accounts
  • Tells you which accounts use the same passwords

Automatic software updates

Automatically keeps software and drives safely up to date. 

  • Covers updates from over 150 software programs (not just Microsoft!)
  • Identifies and installs the latest updates with 1 click
  • Automatically patches your security holes
  • Optimizes hardware performance

Simplify your life and save time

Software companies expect you to know about updates, find the right one and then install it. Software Updater Pro does all that work for you.

  • No more looking for updates
  • No more clicking ‘Next’, ‘Next’, ‘Next’ in installers
  • No more annoying popup messages asking you to update 

Block ads, trackers and infected sites

Included is Browser Safety, a discrete browser add-on for Chrome, Firefox, and Opera that: 

  • Blocks annoying ads and video commercials while you surf
  • Prevents ad networks from tracking you online
  • Stops millions of infected and phishing websites from loading

Award-winning technology that helps protect millions of users.

Antivirus software products comparison graph

No. 1 Antivirus for protection, performance & usability

  • Declared a winner in multiple independent tests 
  • Performance that won’t slow your system down
  • Backed by 30 years of German security expertise for peace of mind that’s priceless
  • Premium customer support with dedicated phone and email

Each element works to reinforce the others

  • Scans for exploits and backdoors on your system to block vulnerabilities
  • Patches vulnerabilities with the latest software and driver updates
  • Defends your passwords – the weakest point in most people’s security

Better than your browser for storing passwords

Browser security is not enough because passwords are unencrypted and vulnerable. Password Manager is essential in keeping passwords securely encrypted, stored, and accessible. 

Does far more than Windows Update

Windows only updates your Windows software; not third-party apps. Internet Security updates all your software, apps and drivers automatically (if you choose) for complete peace of mind.

Avira has more than 35 years of online security experience
