Avast Premium Security — Protection you don’t have to think about

You probably only think about antivirus software when something goes wrong — after clicking a suspicious link, landing on a fake banking site, or connecting to an unsecured Wi-Fi network.

Avast Premium Security is built for exactly those moments you can’t plan for. It works quietly in the background, blocks threats before they reach you, protects your personal files from ransomware, and keeps online banking and shopping secure. You get powerful, all-around protection without performance slowdowns or constant pop-ups — so you can focus on what matters most.

Practical features that truly matter day to day

Great security software doesn’t just sit there — it actively protects you from the problems you’re most likely to face, without getting in your way. Avast Premium Security focuses on real-world situations and delivers tools that make sense in practice, not just on paper.

Real-time malware protection

Threats don’t wait — and neither does Avast. The moment a malicious file tries to run — whether it’s a hidden virus in a download, spyware in an attachment, or a Trojan from a questionable website — Avast Premium Security blocks it instantly. No waiting for scheduled scans, no manual action required. Continuous, automatic protection that lets you browse and work with confidence.

Secure online banking & shopping

Online scams are getting harder to spot. Fake websites often look nearly identical to your bank or favorite store. Avast’s advanced anti-phishing technology checks every site in real time. If a page isn’t legitimate, you’ll know before entering a password or credit card number — preventing costly mistakes before they happen.

Protection for your personal files

Your documents, photos, and tax records are more than just files — they’re part of your life. Ransomware attackers know this, which is why private devices are targeted just as often as business PCs. Avast’s ransomware protection locks down sensitive folders and prevents unauthorized apps from modifying or encrypting them — keeping memories and important documents safe.

Stronger protection for your home network

Your home Wi-Fi is the gateway to all your devices — and only as secure as its weakest link. Avast’s Wi-Fi Inspector scans your router, connected devices, and network settings for vulnerabilities like weak passwords or outdated firmware. It then guides you step by step to fix issues — so hackers can’t slip into your digital home.

Privacy for camera & microphone

Silent spying is a real risk. Some apps and websites can access your webcam or microphone without you realizing it. Avast gives you control back by blocking unauthorized access attempts. You’ll be notified whenever something tries to use your camera or microphone — and you decide whether it’s allowed.

Safely test suspicious files

Not every dangerous file looks suspicious at first glance. Maybe it’s a tool from a forum, a program from a friend, or a download you’re unsure about. Avast’s Sandbox feature on Windows lets you open and run files in a secure, isolated environment. If the file is safe, you can use it normally. If it’s malicious, your real system stays untouched.
