All good things come in three's

Free Security takes a three-pronged approach to protecting and enhancing your digital world.

All the protection you need, whenever you need it

Threat protection has evolved to better suit your digital lifestyle. That’s why we packed Free Security with a diverse spectrum of features.  It safeguards you, your data, and devices from all types of threats (including the vulnerabilities lurking in your own machine, like weak passwords or outdated software). 

So, you can bank, shop, game, browse… you’re free to do whatever you like, and do it safely.

 

Anonymous in everything you do

 

Surveillance has become a part of everyday life so it’s time to take back control of your data. Every trace you leave online, what you buy, where you are, what you search for, which passwords you use—you’re being tracked by third parties. 

Avira keeps it private and for your eyes only by making you invisible online. 

 

Make your devices feel like new again

A…slow…device…that…keeps crashing and a battery that fails on you? That’s frustrating. It also makes you less efficient. That’s why Avira Free Security comes with built-in performance optimizers. They accelerate boot times, extend battery life, and rid your system of junk. 

The result? A clean, stable device with more space for all the things you love, like photos.

 

Billions of reasons to get more than antivirus.

Click on the pie chart to learn more about each threat.

Threat landscape
Pie Chart with 7 slices
  • $11.5 billion

    global damage costs due to ransomware

    Ransomware takes your PC hostage and denies you access to your data unless a ransom is paid. Avira Free Security comes with a built-in, powerful anti-ransomware.

  • 350,000

    new malicious programs every day

    Viruses, trojans, worms, and co. are flooding the internet. Avira Free Security includes a multi-award-winning antivirus that keeps threats well away from your PC.

  • 2.2 billion

    stolen passwords & email addresses

    These were leaked online last year in the infamous Collection #1-#5 data breaches. Avira Free Security generates unhackable passwords for all your online accounts, protecting you against the financial consequences of identity theft.

  • 2.2 million

    routers with security vulnerabilities

    In 2019, security vulnerabilities were discovered in millions of routers. These “doorways” allow hackers to enter private networks and intercept confidential data. Avira Free Security scans your home network for vulnerabilities.

  • 5,000

    annoying popups seen daily

    Every day we’re bombarded with ads online. Avira Free Security blocks annoying ads—and shields you from third parties trying to track your internet activities.

  • 89 million

    Windows PCs with outdated software

    Around 163 million devices participated in data collection—55% were running outdated software. Old software comes with security vulnerabilities that are easily exploited by hackers. Avira Free Security helps keep your software securely up to date.

Privacy by design: We don't sell your data.

Unlike most security vendors, Avira doesn't sell your data and never will. Nor do we share your data with 3rd parties such as government, Big Tech or advertising networks.

Award-winning technology that helps protect millions of users.

Secure your digital life with one smart click

Avira Free Security — free internet protection & much more

The cyberthreat landscape is constantly evolving and becoming ever more complex. That’s why your internet protection should be just as sophisticated and keep pace with these developments. From malware like viruses, Trojans, ransomware, and spyware to phishing, zero-day, man-in-the-middle, and brute force attacks — the list of online threats is long. They target your digital devices and confidential data and files, causing significant damage.

To better protect yourself from various online threats, we developed Avira Free Security: Your free all-in-one solution that includes several tools to improve your internet security and online privacy as well as tune up your device. Its first line of defense is a powerful antivirus protection solution with sophisticated security technology. This is coupled with frequent virus definition updates for virus-detection capabilities you can count on. Our free internet protection solution also includes a VPN for safer and anonymous surfing, a browser safety extension with phishing protection, a password manager, and tune-up tools to free up storage space and put the zip back into your device. Avira Free Security for Windows also includes a software updater for zero-hassle updating of your programs and drivers.

 

Smart Scan — your free comprehensive check

The Smart Scan feature of our free internet security solution Avira Free Security checks your system for internet security, online privacy, and performance issues with a single click. It helps you detect malware and network threats, identify outdated software, and remove tracking cookies and unnecessary files cluttering up your system — and a whole bunch more. Once you’ve run a Smart Scan, a single click is all it takes to fix all the issues or view the details and select which ones you want to fix.

 

Free internet protection — greater online security thanks to enhanced levels of protection

Avira Free Security helps you protect yourself comprehensively against online threats such as malware, cyberattacks on software vulnerabilities, data theft through phishing websites, and web tracking thanks to a range of features and tools — allowing you to surf the internet more securely and privately as well as browse freely. Download our internet security solution Avira Free Security now and enjoy free-of charge PC security with malware and phishing protection.

  • Antivirus protection and virus scanner

Cloud-based real-time protection monitors your system constantly and automatically in the background. Suspicious files are analyzed in the Protection Cloud and, if necessary, rendered harmless. The virus scanner helps you regularly scan your hard drive for malware and remove it on discovery

  • Software updater (Windows feature)

Take the hassle out of updating your drivers and programs — even from third-party providers — thanks to the software updater. It’s included with Avira Free Security and quickly closes dangerous security holes in outdated software which cybercriminals can exploit to inject malware or access your device.

  • Browser safety extension

Block unsafe and phishing websites as well as malicious downloads with the browser extension included with Avira Free Security. Avira Browser Safety also boasts an ad blocker and anti-tracking features.

 

VPN and password manager for greater online privacy

When emailing or shopping and banking over public Wi-Fi hotspots, there’s a risk that cybercriminals will intercept the data you send and receive online, like passwords and other access data or confidential emails. Thanks to Avira Free Security, you can not only encrypt your device’s online traffic but also strengthen the protection of your online accounts.

  • VPN with 500 MB data/month

The free Avira Free Security solution includes a VPN so you can hide your IP address and surf anonymously. And since the VPN also encrypts everything you send and receive online, you can surf more securely even on unsecured public Wi-Fi hotspots.

  • password manager

Generate strong and, most importantly, unique passwords for your various online accounts with the password manager included with Avira Free Security. This means that if one of your online accounts is hacked, your others won’t be at risk because they’re protected with a different password.

  • Windows privacy settings customization (Windows feature)

Customize a range of settings, such as to prevent Microsoft from collecting information about your use of Microsoft services and applications. 

 

Optimization tools to free up storage space and boost performance

Over time, more and more junk accumulates on our computers, eating up precious storage space and sapping their performance. Our free-of-charge solution Avira Free Security helps you give your device a thorough clean and put the zip back into it.

  • Cleaner (Mac feature)

Remove unnecessary data such as cache, log, and temporary files and free up disk space with Avira Free Security for Mac’s Junk Cleaner.

  • Cleaner & additional tuning tools (Windows features)

Give your PC a thorough clean up — including the registry and your browser — and also reduce the start time of your device with Avira Free Security for Windows’ tune-up tools.

 

Free online security for your mobile devices too

Since cybercriminals not only target computers but increasingly also smartphones and tablets, we also offer a free all-in-one solution with a Smart Scan feature for your mobile devices. Avira Antivirus Security for Android includes antivirus protection, a VPN with 100 MB of data per day, plus storage- and performance-tuning tools. Avira Mobile Security for iOS also includes a VPN and a host of protection features.

The internet protection solution Avira Free Security costs nothing at all and offers all the basic tools you need to boost your internet security, online privacy, and device performance: Antivirus protection you can count on, a VPN for anonymous surfing and encrypted online traffic, a password manager to create strong passwords, a browser safety extension with phishing protection, and tune-up tools to free up space and boost your device’s performance. Avira Free Security for Windows also includes a software updater for zero-hassle updating of your programs and drivers.

You can download our free-of-charge internet security solution Avira Free Security for devices with the following Windows and macOS versions:

  • Windows 7 with Service Pack 1
  • Windows 8
  • Windows 10
  •  Windows 11
     
  • macOS 10.15 (Catalina)
  • macOS 11 (Big Sur)
  • macOS 12 (Monterey)
  • macOS 13 (Ventura)
  • macOS 14 (Ventura)

Yes: Our internet security solution Avira Free Security is available for download at no cost. The free internet protection solution includes all our basic tools to boost your cybersecurity, online privacy, and device performance. You can also make an in-app purchase and take out a monthly or annual subscription to our advanced all-in-one solution Avira Prime and benefit from many additional features for up to 5 or 25 devices.

These include advanced ransomware protection, a VPN without data limits, dark web monitoring for your email address§, and all Pro mobile apps. Avira Prime for Windows offers even stronger phishing protection with integrated web protection and email protection, the Avira Firewall, even more thorough PC cleaning and tuning, as well as automatic software updates.

§Dark Web Monitoring is only available to residents of Germany. The email address you use to purchase the product will then be monitored immediately following activation.

In short, there is no difference. When we added additional tools and features such as the VPN, the software updater, the optimization tools, and the password manager to our standalone Avira Free Antivirus solution, we renamed this all-in-one solution Avira Free Security. So that even those users who don’t know this and who are searching for Avira Free Antivirus can find what they’re looking for, we still offer Avira Free Security under the name Avira Free Antivirus.
