Malware notices for Every App

I’ve had Avast for several months on an android tablet. Suddenly today I get possible malware notices for every app I opened. (All obtained from Google Play.)

For one of the apps it states the problem is Android:Onexuan0G[PUP], for the others (so far) it states Android:MoibleSpy-AD[PUP].

Are these false?

Can you please advise whic tablet do you have and which apps are detected? Thanks.

Just now when I turned the tablet back on Mobile Security & Antivirus/ Mobile Backup & Restore were updated from Play Store automatically. And I’m no longer getting those messages. Should I assume the two are related?

(And for your reference, the device is a Samsung GalaxyTab, Model SCH-1800 and the issue occurred with every app I’d opened including Y!Mail, the indeed.com app, tumblr, WordsWithFriends, a maps app.)

Thank you.

Is it not by any chance tablet from Verizon?
