I am looking for a free antivirus for my grandmother's cell phone. I've heard that Avast is a great option, but I wanted to confirm if the free version for Android updates its virus definitions automatically. Please help me!

Do you know how long the automatic update process takes? When my grandma's phone connects to the Internet, I tap on the three lines, then on "Options", "Updates", and I see that the date of the virus definitions are still from the previous day or from two days ago. I have waited up to one hour to see if the virus definitions will update automatically, but the only way to update the virus definitions seems to be tapping on the "Search for updates" green text. I have tried with another Android phone and a tablet, and the virus definitions don't seem to update automatically.

Hi,

Virus definitions on mobile are not regular. If you go to "Settings" > "Activity log"  it should show the version and time of the last update.

I had noticed the same thing. The virus definitions sometimes don't seem to be up-to-date. So that means that even if the date of the virus definitions is not the current date (because the virus definitions on mobile are not regular), my device will be protected? Is it because of Avast's "real time protection" or something like that? Will the virus definitions date eventually update to the current date? Can you please let me know??

Hi,

Even if the virus definitions are a day old, the shields are still running, keeping malware away. The virus definitions will also automatically update once the new virus definitions are available.

I'd like to ask one more thing: Now I understand that the virus definitions are not regular on mobile, and that even if the virus definitions are a day old, my phone is still protected by Avast... Then why does the virus definitions date change to the current date if I update the virus definitions manually (by tapping on "Check for updates")? I'd like to know because I feel like the current/new virus definitions are always available to be downloaded/installed, but the Avast Android app just doesn't update them automatically. Please let me know when you have a minute.

Hi,

The app checks for new updates in cycles (every few hours), and if you are not connected to the internet all the time, it might seem that way. The best thing would be to keep the phone connected to the internet for a few days and then look at the "Activity log" in Settings in Avast Mobile Security. You should see if there were any attempts to check for updates.

Hi, so frequently it seems as though someone is turning off my VPN on my phone. I will notice the icon is not on so I will go into my app then suddenly it is reconnecting.  Is someone hacking in and shuting it down ? Or does this mean something else?

This really should be its own new topic as it isn't really related to this topic (hijacking).
There is a sub-forum for mobile products, since you don't mention your phone or its operating system, what version of avast you have or even if it is the Avast VPN. Information really is the key to being able to help.
