Frequently Asked Questions
Which Avast product is best for Windows 10/11?
For Windows 10 and 11, we recommend Avast Premium Security 2025 for comprehensive protection. This latest version provides advanced ransomware protection, webcam security, sensitive data shield, and more. If you want an all-in-one solution, Avast One provides complete security, privacy, and performance features. On our website, you can download the fully activated premium versions for free.
Do I need antivirus if I have Windows Defender?
While Windows Defender provides basic protection, Avast Premium offers significantly more advanced security features and better threat detection capabilities. Independent tests consistently show that Avast provides superior protection against malware, ransomware, and other threats compared to Windows Defender. Our premium version includes features like ransomware protection and webcam security that Windows Defender doesn't offer.
Will Avast work on older versions of Windows?
Avast supports Windows 7 (with Service Pack 1) and newer versions. For older versions like Windows XP or Vista, you may need to use older versions of Avast products, which may not receive the latest updates. Our latest 2025 version is optimized for Windows 10 and 11 but will work on Windows 8.1 and 7 as well.
How do I install Avast on Windows?
Simply download the premium installer from our website, run the file, and follow the on-screen instructions as shown in our 3-step installation guide above. The installation process is straightforward and typically takes just a few minutes to complete. No activation code or payment is required as our version comes pre-activated with all premium features unlocked.
Can I use multiple Avast products on the same Windows PC?
Yes, many Avast products are designed to work together. For example, you can use Avast Premium Security alongside Avast Cleanup Premium and Avast SecureLine VPN. However, you should not install multiple antivirus products (like Avast Free Antivirus and Avast Premium Security) on the same system. Our premium bundles often include multiple products that are designed to work together seamlessly.
How do I activate the premium features?
The premium version available on our website comes pre-activated with all premium features unlocked. Simply download and install the software following our 3-step installation guide, and you'll immediately have access to all premium features without needing to enter any activation code or payment details. This includes features like Ransomware Protection, Webcam Shield, and Sensitive Data Shield.
Is this premium version legal and safe to use?
The premium version we provide has been modified to give you access to all premium features. While this allows you to experience the full capabilities of Avast's premium offerings, it's important to note that this is for educational and evaluation purposes. The software is scanned for malware and is safe to use on your devices.
Will I receive updates for the premium version?
Yes, the premium version will still receive virus definition updates to ensure your device remains protected against the latest threats. However, major version updates may require downloading a new activated version from our website. We regularly update our offerings with the latest versions as they become available.
What's the difference between Avast Free and Premium Security?
Avast Premium Security includes all the features of Avast Free Antivirus plus additional advanced protection: Ransomware Shield to protect your files, Webcam Shield to prevent spying, Real Site to prevent DNS hijacking, Sensitive Data Shield to protect your personal information, and advanced firewall protection. Our website provides the fully activated premium version for free.
Does Avast slow down my Windows PC?
No, Avast is designed to have minimal impact on system performance. The latest 2025 version has been further optimized to use fewer system resources while providing even better protection. Features like Game Mode ensure that your PC's performance isn't affected during gaming or when using full-screen applications.
