About this app

Avast One is the free, all-in-one service that combines antivirus, extra privacy (VPN), security, and performance tools to help you stay private and safe anywhere you go online and on every device.

• Make your connection to any network secure & private with a VPN
• Stay safe from viruses & malware with an advanced antivirus
• Find out if a password is compromised in a new data breach so you can quickly re-secure your online accounts
• Boost your device’s storage & performance by cleaning junk and stopping apps running in the background

Device protection
• Advanced antivirus: Automatically scan for viruses and other kinds of malware, including spyware, Trojans, and more. Web, file, and app scanning provide complete mobile security.
• Virus cleaner: Safely remove viruses and malware from your phone. Uses real-time intelligence from the largest threat-detection network of 435 million Avast users.
• Web Shield: Scan and block malware-infected links, as well as Trojans, adware, and spyware (for privacy and safe web browsing). Automatically fixes mistyped URLs so you avoid dangerous sites.
• Wi-Fi Scanner: Check a network’s encryption and password strength so you can avoid joining a network where your safety or privacy would be at risk.

Online privacy
• Military-grade security: Make your connection to any network secure & private with a Virtual Private Network (VPN).
• True online privacy: Hide your online activities so you can do what you want online without anyone finding out thanks to a VPN.
• Access streaming while abroad: Stream your favorite movies and shows with access to your streaming subscriptions while traveling by using a VPN to change your device’s location to any of 35 countries.
• Data Breach Monitoring: Scan new data breaches for leaked passwords linked with the email address you use to sign in to your online accounts. Find out if the email and password combination to any of your online accounts is compromised so you can quickly re-secure your accounts and prevent intruders from getting access.

Smooth performance

I have used the regular version of avast in the past on a computer that I once owned & on some of my smartphones & tablets, it worked wonderfully, loved it. But, I really love this avast one even better. Especially when I go to download an app, it lets me know if the app is safe or not, that to me is a good feature. I love the other features as well. Keep up the good work avast. You have been keeping my devices safe for quite some time now. Would highly recommend your app to anyone. Your #1.

This app is definitely a keeper. It has several levels of Scanners, a VPN with a weekly limit and more functions that can be unlocked by upgrading as well as making the VPN unlimited. It has ads for upgrading, but a reasonable amount and they do not interfere. Many kudos to the developers for the free version.I have not upgraded yet but plan to.

I am seeing that in the background improvement are made. At first when Avast One was new the only way it installed is if it were clean not even the free version of a conflicting Avast program was running. I have kept some of my mobile subscription and Avast One active and sometimes the Avast Pro VPN runs too. And now I am seeing multiple VPNn on the same device running sometimes 3 of them independently. So probably someone is managing this well. Not easy with all these security threats of today.
