Tech corner
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. Avast Premium Security alerts you to unsafe websites before you load them up, so you can live your online life with total confidence.

Stop hackers from taking over your PC
Remote access attacks are on the rise — and the last thing you want is for a hacker to remotely take control of your PC and infect it with malware or lock your files with ransomware. Avast Premium Security now protects your PC against these attacks.
Tech corner
The most dominant vector for remote access attacks is Microsoft’s Remote Desktop Protocol (RDP). RDP is a useful tool for granting authorized remote access when needed, but can be a loophole for an attack if not used properly. Remote Access Shield protects against such attacks in three ways:
- Detect and block brute-force attacks by counting unsuccessful login attempts within a specified period of time and blocking the IP address associated with these attempts.
- Secure known OS vulnerabilities and prevent RDP exploit attacks aimed at breaching them.
- Automatically block all IP addresses known to distribute malware by exploiting RDP ports. Our database is continuously updated using our AI algorithm.
Get full protection for your Mac
Keep your Mac secure and protect your personal files against sophisticated online threats like ransomware attacks.
Tech corner
Avast’s anti-ransomware protection ensures that your personal and sensitive files, photos, and documents stay safe from hackers looking to access and exploit them by holding you to ransom. Avast’s Ransomware Shield automatically prevents untrusted applications from modifying, deleting, or encrypting your files, giving you the peace of mind you need.

You may still be wondering...
Why is it worth paying for antivirus protection?
While free antivirus software comes with all the essential protection you need to stay safe online, premium antivirus software has additional features and benefits that can both improve your security and give you the tools you need to counter new threats as they emerge. With Avast Premium Security, you’ll automatically detect and avoid malicious websites, and defend against remote hacking attacks. And you can extend these added protections across up to ten devices — allowing you to protect your family and friends.

What's the difference between Avast Premium Security (Single-Device) and Avast Premium Security (Multi-Device) subscriptions?
While both Avast Premium Security subscription types offer complete online security, each is suitable for a specific number of devices. An Avast Premium Security (Single-Device) subscription protects one device on the platform of your choice. The Single-Device subscription type can be used for one of the following products:
An Avast Premium Security (Multi-Device) subscription protects up to 10 devices, regardless of platform.
Avast Premium Security (for PC, Single-Device)
Avast Premium Security (for Mac, Single-Device)
Avast Mobile Security Premium (for Android, Single-Device)
Avast Mobile Security Premium (for iOS, Single-Device)
Can I change the 10 devices activated with my Avast Premium Security (Multi-Device) subscription?
Yes. If you have 10 devices already activated using your Avast Premium Security (Multi-Device) subscription, you must uninstall Avast Premium Security from one device before activating it on a new device. Once uninstalled, you can install Avast Premium Security on your new device. To activate the product on the new device, go to your Avast Account, and retrieve the activation code for Avast Premium Security (Multi-Device).
Is it necessary to uninstall my previous Avast Antivirus version before upgrading to Avast Premium Security on my PC?
If you already have Avast Pro Antivirus, Avast Internet Security, or Avast Premier version 7.x or later, you do not need to uninstall your current version. Avast Antivirus setup automatically detects these versions and upgrades the existing installation to Avast Premium Security (for PC, Single-Device).
What are the features of Avast Premium Security?
Avast Premium Security is an Avast product that offers antivirus protection and advanced security for your PC against online threats. It allows users to safely shop and bank online, avoid fake websites and phishing scams, block web spies, and more. Avast Premium Security also includes key features from Avast Internet Security and Avast Premier products, both of which no longer exist.
