Avast Internet Security
This product is now a part of Avast Premium Security.
We’re always striving to offer our customers the very best in online security. That’s why we’ve developed a single solution to cover all of your online security needs, on all of your devices.
For those that want deeper privacy protection
Tweet to your heart’s content, shop, or bank safely and ‘like’ – well, anything you like. Internet Security’s intelligent threat-detection keeps your identity safe online, and now adds an extra layer of anti-ransomware protection for your most important files and photos.
NEWKeep hostage-takers off your files
Hackers demand an average of $643 from ransomware victims. Internet Security now walls off your private files & photos so they can’t be encrypted and held hostage.
Avoid fake websites
Hackers can easily create a replica of your banking site to steal your logins and passwords. Internet Security encrypts your data so your information stays safe.
Spot scam emails
Today’s phishing emails are not as obvious as “you’ve won the lottery.” Internet Security stops more than the usual strange text and sender.
Firewall your data
The data sitting on your PC is the key to identity theft. Internet Security’s Firewall is the strong gatekeeper you need to stop hackers from accessing it.
Take a look inside
Internet Security offers many layers of protection to keep you safe and your devices running smoothly. All of the advanced features below are included in your Internet Security software.
Keep hackers on the other side of the wall with this essential security feature that monitors and controls what goes in and out of your computer.
Dodge spam and other malicious content, so you can focus on the emails that truly matter.
Protect yourself from hackers who attempt to hijack your DNS (Domain Name System) settings, redirect you to fake sites and steal your banking details.
Automatically detect weaknesses in your home Wi-Fi and strangers piggybacking on your network.
Detect and block viruses, malware, spyware, ransomware, and phishing. We use smart analytics to stop threats before they affect you.
