FAQs

Ever since Microsoft ended Windows 7 support on January 14th, 2020, technical support and security updates from Microsoft are unavailable to people who still use this operating system. Fortunately, there’s still a way to secure your Windows 7 PC: third-party security software, such as the kind offered by Avast.

The same way you protect any PC from a computer virus: with a powerful antivirus!

But if you’re looking for a good antivirus for PC viruses, you won’t find one better than Avast Antivirus for Windows 7. Our powerful Windows 7 virus scanner and removal tool will find any malware on your system and remove it, as well as prevent your PC from becoming infected with any other computer virus in the future.

No matter what type of malware is threatening your system, Avast is the solution.

Windows 7 does have Microsoft Security Essentials (MSE) included automatically. But it doesn’t have Windows Defender, which appears it later versions of Windows. Even before Microsoft stopped updating MSE, it only offered a very basic level of security. For real Windows 7 security,  it’s best to use a powerful and trusted third-party antivirus to keep you safe.

It is possible to get Avast Antivirus for Windows 7, as we still support the operating system. We will continue to ensure that both our paid and free security remains compatible.

Avast offers one of the best Windows antivirus apps. For one, we use the world’s largest threat detection network combined with six layers of powerful security to identify and block malware threats, including zero-day threats. Secondly, our antivirus offers powerful spyware removal tools, protection against ransomware on Windows 7 PCs, and comprehensive virus scans. Finally, our large selection of options and settings ensures you get exactly the level of protection you want.

If you do choose to upgrade from Windows 7, you will need to uninstall and reinstall your antivirus software, which you can do for free. If you have the paid version of our product, Avast Premium Security, you may need to input the activation code again to retain your paid features. Once you do that, you’ll be able to enjoy the latest and greatest from both Avast and Microsoft, specifically if you’re upgrading to Windows 10 and Avast Antivirus for Windows 10.

Yes, there is. Go to our Avast installation file page. Make sure that you’re in the Home section of the page and download the file you want beneath Avast antivirus installation files. The download file is compatible with most versions of Windows. Try our free, offline antivirus installer for Windows 7, also compatible with later versions of Microsoft’s operating system. It provides a great way for you install all the software files you need if you have slow or limited internet connectivity. 

You don’t need a trial. Why? Avast Free Antivirus is already a free product, and we plan to keep it that way. If you decide not to keep it, it’s also easy to uninstall.  However, we do offer trial periods for our paid-for cybersecurity apps and services. For example, Avast Premium Security has a 30-day trial and also works on Windows 7.
