Shop and pay securely without worrying about your financial credentials being compromised. Avast Premium Security scans websites to make sure they’re legitimate, so you can avoid fake websites trying to steal your information.
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. Avast 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
Help to prevent hackers from taking over your PC
Viruses, ransomware, scams, and other attacks have always targeted Windows more than any other operating system, but what’s concerning is the rise of remote access attacks. 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 — Avast Premium Security helps protect your PC against such attacks.
How Remote Access Shield works
Our Remote Access Shield helps protect against cybercriminals trying to get unauthorized access to your PC via Microsoft’s Remote Desktop Protocol (RDP) by:
- Blocking brute-force attacks and associated IP addresses.
- Secure known OS vulnerabilities and prevent RDP exploit attacks.
- Automatically block all IP addresses known to distribute malware by exploiting RDP ports.

How anti-ransomware protection works
