Buy Avast – protection for every device in your household from a single source

A typical household today has a Windows laptop, a MacBook, two smartphones and perhaps a tablet – and every device needs protection against malware, phishing sites and insecure Wi-Fi connections. This is exactly where Avast comes in: the Prague-based company has been developing security software since 1988 and offers packages that cover several platforms with one licence. At Lizenzindustrie, you receive your Avast licence as an instant download, with the licence key sent straight to you by email.

Which Avast package is right for you?

The key question is which devices you want to protect. If you use Windows exclusively, Avast Internet Security is sufficient for most users: you get a firewall and phishing protection without paying for Mac or mobile features you don't need. As soon as a Mac or smartphone is added, Avast Premium Security is the more sensible choice, because one licence can then be used across platforms.

The Ultimate Suite is worthwhile if you want to use a VPN anyway – as a package, this is usually cheaper than buying antivirus and VPN separately. If you already have antivirus protection and only want to browse securely on the go, go straight for SecureLine VPN. You can find further alternatives in our Multi-Device Antivirus category.

Why buy Avast at Lizenzindustrie?
