Premium Security

Here's what you get with Premium Security in the Avast One app

Premium Security offers award-winning antivirus, plus protection against sophisticated scams, so you can relax knowing that you're better protected.

Email scam protection

Stay ahead of potential email scams

Connect Email Guard with just a few clicks on your Premium Security. It flags potential email scams, phishing, and infected attachments before they get to you on Gmail, Outlook, and other popular email providers, no matter which computer you're using.

How to set up Email Guard on your device

Install Avast One with Premium Security and follow the on-screen instructions to set up the app.
Open the app, navigate to the Scam Guardian Pro section, and select Email Guard.
Sign in to your Avast Account and add up to five email accounts.

Once set up, Email Guard flags suspicious emails directly in your inbox. It monitors your selected email accounts 24/7 and lets you know right away if any new emails in your inboxes look like potential scams.

SMS and call scam protection

Block scam SMS messages and scam calls

Get advanced, AI-powered scam protection that travels with you wherever you go. It works continuously to detect sophisticated phone and SMS scams, giving you advanced protection so you'll always know when it's safe to respond. With 24/7 protection, scammers will have a hard time getting through. You can answer with peace of mind, whether it’s loved ones or a delivery update.

Website scam protection

Shop, bank, and pay online more safely

Premium Security scans websites to make sure they're legitimate, so you can better avoid fake websites trying to steal your information. Shop, bank, and pay more securely. Worry less about your financial credentials being compromised.

How fake websites work

Spoofed websites are commonly used by cybercriminals to steal your data and personal information. A spoofed website looks like the legitimate version but is fake and designed to steal information like your passwords and other personal data. Premium Security alerts you to unsafe websites before you load them up, so you can live your online life with more confidence.

Whichever devices you use, we’ve got you covered

Boost your PC’s defense against hackers trying to gain access

The last thing you need is a hacker remotely taking control of your PC and infecting it with malware or locking your files with ransomware. But no need to worry, Premium Security helps protect your PC against such attacks.

Our Remote Access Shield helps protect against cybercriminals trying to get unauthorized access to your PC via Microsoft’s Remote Desktop Protocol (RDP) by:
