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
• Junk Cleaner: Make more space for your photos, videos, and music by cleaning out junk files with our most efficient cleaner yet. Easily clear unnecessary data, system caches, and more.
• Task Killer: Get a performance boost by killing apps you aren’t using. Stop apps running in the background to free up your device’s memory and help it run faster.

I've had this app for weeks and it has not once completed a scan, most certainly not in "a few minutes". And it keeps harassing me to scan my own, totally secure network. The only progress it's made since the last time I'd uninstalled it is that it's not bogging my tablet down. Try again Avast. Uninstalling a second time. I'll try again in a couple more years 😅

Hey Monica, we are very sorry to hear about your negative experience. This really sounds unusual to me though. Normally our app has no issues with finishing the scan. If that isn't your case, please reach out at android@avast.com. We would really like to investigate it. David

3 devices, caught one virus on ok be so far. This is a very hard one. They went into Windows feature power support, changed all my settings to come in legitimately. I changed it back, they withdrew, I'm scanning now. I think they took their tools off and are dormant. They will try again maybe. I hope not. Three days I've been at this until I downloaded avast. I need more help maybe. If you want to pull up the information on these devices and help me get rid of this, I would appreciate it!

Since the last two download updates I keep getting warning my wifi is not secure. Possible TLS/SSL problems. Man in the middle issues. Use VPN before using for passwords, etc. Well it does this on every wifi i try to connect to. My cousins, friends, ect. Cannot believe every wifi is a problem. Think avast has a problem. Spent almost 3 hours with cable company. They could not find a wifi issue.
