Latest UPDATE

On Google store there is an update, which does not install? I have tried several times with no luck, on several devices, both phones and tablets.
Any suggestions?
Version 5.1.0 Updated on Mar 17, 2016
Thank You

Hi, we have noticed a wave of similar messages, but the error is on the side of Google Play Store. We have been in touch with them and hope it will be fixed soon. You can try to update Avast directly from “Google Play Store – My apps” list using “Update all” button.
