Hi. I have a Nexus 6P running Android 8.0. I’m using Avast Mobile Security.
Avast can’t update. I get messages all the time, from Avast Mobile Security, telling me “Warning! Issues detected.”
I tap it, and get a “Virus Definitions outdated” message. I tap “RESOLVE,” and get “Virus definitions update failed.”
What’s going on?
