Frequently Asked Questions

What is Avira Free Antivirus?

Avira Antivirus is a popular antivirus software that delivers an intuitive yet powerful set of tools to help the most novice computer user secure their PC and the online world.

Recommended for anyone who wants protection on their PCs, mobile devices, and any network they connect to. Whether you are looking for complete PC protection or just want peace of mind when connecting your tablet with a Wi-Fi hotspot, the company has something perfect for you.

What makes Avira Free Antivirus different?

Avira has a more user-friendly interface as it includes explanations for each component of the program. It also has a Sandbox mode, which lets you test suspicious files before letting them affect your computer and detects any change in the system after they are used.

Avira Free Antivirus also features Real-time Protection that constantly monitors your PC 24/7, Alerts you when security threats are detected, and automatically closes the gaps to secure your computing environment.

How to update Avira Free Antivirus? 

Avira Free Antivirus can be updated using the "Check for Updates" menu option found in the settings. This button appears near the bottom of the Settings screen. Clicking on this button opens a dialog window reflecting whether there is an update available.

If so, clicking on "Download and Install Now" will start downloading and installing the new update to Avira Free Antivirus, automatically or manually if desired). Alternatively, click on "Check for Update (manual)" copies a link to your clipboard, which links to a webpage where you can manually find out any new updates available for download. 

Why is Avira Free Antivirus slow?

The slowdown is due to file sharing, email attachments, and many external links on social media sites. Avira Free Antivirus scans each file (or link) before allowing it to be shared or sent out. File headers are always scanned, which consumes time and system resources. If Avira detects a malicious code in an attachment, then the antivirus will stop the entire process from executing altogether. 

How to change language in Avira Free Antivirus?

You can change the language in Avira by following these steps:

1. Click Settings > Language.

2. Check the boxes of the languages you would like to display throughout your Avira application and press Next to go to the next step, if desired.

3. Press Save Changes if you are satisfied with your selection of languages or press the Cancel button above the settings window for changes not being made at this moment.

4. After saving, all other selections within the program will automatically change accordingly to selected language-specific options that were set either by default/default system settings selection or individual user preference setting accepted upon installation process 

How to turn phishing detection in Avira Free Antivirus off?

Ensure that the email scanning function is turned off in Avira. Navigate to Settings, then Protection, and finally turn off the 'Email Scanning' function. Navigate to Network Control when it appears on your screen to mark a message as safe or unsafe. To unmark a message as safe or unsafe, go to Menu and click Mark items Safe or Unsafe.

The sender's address would have a safety symbol next to it if you marked them as safe, while the unopened mail icon will appear next to an item/message that needs action taken from you if marked as unsafe.

What are the benefits of using Avira Free Antivirus? 

Avira Free Antivirus is a green, fast-working, zero-cost protection for your PC. It's light on resources and easy to use. Avira Free Antivirus scans programs before they are loaded into memory.

The antivirus engine starts with the "bootkit" defense modules that can work independently of the OS kernel (and outside the file system), so malware that targets Windows Explorer or other core structures will have minimal success bypassing AV software running in this mode. Your vital documents remain safe because Avira automatically encrypts them when you put them on an external storage device like a USB thumb drive or SD card.

What kind of protection does Avira Free Antivirus provide? 

It offers protection by scanning the operating system and applications on your computer for known threats. The results of these scans are rated with a threat level or "threat score". Every time you access the Internet, the real-time protection system analyzes files that are downloaded by Avira and their links to online content. Should it find any known malware, it will block it automatically before any harm can be done.

This protection is fast because heuristic analysis looks at each new file on the fly and decides whether or not a particular program might be suspicious. The latest version also incorporates proactive detection methods like seeding trusted files with libraries of viruses to monitor how they propagate if uploaded onto another machine.

Does Avira Free Antivirus work on Android, Windows, Mac OS? 

Avira Free Antivirus is available for Android, Windows, and Mac OS. If you have an Android device running Lollipop (5.1) or higher, you can download the Avira App from Google Play Store.

Similarly, for Windows computers, there are pre-installed versions and free downloads that are compatible with your operating system for both 32-bit and 64-bit systems. Mac hardware users are a no-brainer as Apple devices run the same operating system as their computer equivalents. Still, because they're explicitly optimized for them, they require installs through different means (iTunes). 

How often will I be prompted for an update once installed?

The program will check for new updates when the computer is idle. It has a prompt to give the option of updating or bypassing, and it checks every six hours while active. You can also force an update at any time from within the program by clicking "Update Now" on the right panel.
