How does Avast Antivirus work?

Avast offers both free and paid antivirus packages, and if you are looking for an entry-level solution equipped with great features, the free version will be sufficient for your requirements. Avast antivirus is also easy to install; if you wish to install the free version on your device, you can download it from the official website. After downloading, click on the downloaded link to install it and then “run” the program to activate the antivirus. You might be asked to install Avast’s web browser or other programs during the installation, but it’s essential for you to know that these additions aren’t required. You will have to register yourself at Avast to use it for more than 30 days, but the registration process is quite easy.

The free version of Avast Antivirus has several incredible features, and the package doesn’t have any major hidden restrictions or limitations that will force you to upgrade for advanced features.

The real-time detection by the free version of Avast picks up known threats as and when they appear, and the HTTPS scanning component of the Web Shield feature protects against malware while browsing the web. Also, all unknown files are analyzed by the antivirus to spot the latest malware. In case a threat manages to make its way past all these security features, Avast’s behavior monitoring can detect and alert you to any malware-like actions.

Features at a glance

  • Real-time protection: Both the free and paid versions of Avast are equipped with fully functional antivirus, antispyware, and antimalware. They offer real-time protection of emails, files, web surfing, and more, and also notify you about suspicious files.
  • W-Fi inspector: Avast Antivirus has a Wi-Fi inspector that can detect weaknesses in your home Wi-Fi and can also identify strangers who are piggybacking on your network.
  • Smart Scan: The antivirus has a feature called “Smart Scan,” which can find all those cracks in the system that allow malware to slip in. Everything from unsafe settings and passwords to suspicious add-ons and out-of-date software are scanned to ensure your system’s safety.
  • CyberCapture: This feature automatically locks suspicious files and sends them for analysis in the cloud.
  • Behavior Shield: The Behavior Shield checks all your applications for the slightest hint of a malware. For this purpose, it keeps an eye on their behavior to ensure that they don’t suddenly start malfunctioning and go rogue.
  • Do Not Disturb: The Do Not Disturb Mode is an upgrade to the previous Game Mode feature. It blocks distracting pop-ups when you are gaming, watching movies, or running any application in full screen.
  • 30-day money-back guarantee: If you opt for the paid versions, you’ll be eligible for the 30-day money-back guarantee if the product doesn’t meet your expectations.


Avast antivirus has cross-compatibility, and the free version is compatible with Windows 7, 8, 8.1, and 10. Avast Premium Security is also compatible with macOS 10.10 or higher and Android 4.1 or higher in addition to the Windows versions mentioned. It can also be used on iPhones or iPads with iOS 10.0 or higher, but it is not supported on Microsoft Windows editions earlier than Windows 7, DOS, and Microsoft Windows Server operating systems.

Protection against malware

With over 400 million active users, Avast scans over 200 billion URLs every month and prevents 3.5 billion malware attacks every month. The antivirus always works in the background to ensure that your system remains protected from known and unknown malware. Features like Behavior Shield, File Shield, and CyberCapture are designed to keep malware from entering your device. Whenever you download or run a file, File Shield will immediately scan it for any virus. If the file is deemed malicious, it is moved to the “Virus Chest” and blocked from running to prevent it from harming your device. The Behavior Shield is always on the lookout for malware and monitors apps in real-time for malicious behavior. CyberCapture is another effective feature that detects a suspicious file, locks it from your system, and sends it to the Avast Threat Labs for in-depth analysis. Also, this feature blocks all unrecognized files for added protection.
