Microsoft Defender (formerly Windows Defender) is built into every Windows 10 and 11 install and scores extremely well in independent lab tests. So the honest answer to "do I still need antivirus?" is: for pure malware detection, Defender alone is fine for many people. The real question is whether you want the extra protection layers and tools that a paid suite adds — and that depends on how you use your PC.
Microsoft Defender (formerly Windows Defender) is built into every Windows 10 and 11 install and scores extremely well in independent lab tests. So the honest answer to "do I still need antivirus?" is: for pure malware detection, Defender alone is fine for many people. The real question is whether you want the extra protection layers and tools that a paid suite adds — and that depends on how you use your PC.
Defender protects the device it runs on, with Microsoft's tooling and nothing more. A paid suite is a broader package:
| Feature | Microsoft Defender | Paid suite (e.g. Bitdefender / Kaspersky / ESET) |
|---|---|---|
| Core malware protection | Excellent | Excellent |
| Ransomware folder shielding | Manual (Controlled Folder Access) | On by default, broader |
| Anti-phishing across all browsers | Edge / SmartScreen only | All browsers |
| VPN | No | Yes (limited or unlimited) |
| Password manager | No | Yes |
| Multi-device (Mac, Android, iOS) | Windows only | Yes (one licence, many devices) |
| Webcam / mic protection, parental controls | Limited | Yes |
If you use a single Windows PC for browsing and email and you are careful, Microsoft Defender is genuinely enough — just turn on Controlled Folder Access. The moment you want banking-grade phishing protection, ransomware shielding, a VPN, a password manager or cover for phones and Macs, a paid suite is the better and surprisingly affordable choice.
All of our security licences are genuine, delivered instantly by email and cover the latest 2026 versions:

At KeyVano you can buy genuine software licenses across the DACH region: Germany, Austria and Switzerland. The licenses are valid internationally and are not tied to any country – you get the same prices, the same instant delivery by email and the same support everywhere. Whether you order from Vienna, Zurich, Berlin or anywhere else, the process is identical and free of country-specific restrictions.
For a single Windows PC used carefully for browsing and email, Defender's malware protection is genuinely strong. A paid suite is worth it if you want ransomware shielding, anti-phishing in all browsers, a VPN, a password manager or multi-device cover.
When you install a third-party antivirus, Windows automatically switches Defender's real-time protection off to avoid conflicts. You do not need to do anything — only one real-time engine runs at a time.
Modern suites like Bitdefender and ESET are very light thanks to cloud scanning and idle-time scans. On most PCs you will not notice a difference in everyday use.
Reputable free options (including Defender) are safe, but they often lack ransomware shielding, VPN, a password manager and multi-device support. Paid suites add those layers for a small yearly fee.
Yes. KeyVano delivers software licenses to Germany, Austria and Switzerland. Delivery is instant by email everywhere, prices are the same for all countries, and the license keys work worldwide without regional locks.
