Virus removal

[Gamedpa]

I have a Galaxy Tab Pro SM-T670, and before it was corrupted Malwarebytes told me every app was infected. Since then efforts to use Malwarebytes have failed, it no longer works. I cannot download a new virus since connecting to the internet risks the virus spreading to my other devices. How can I get a virus protection app on the device? Or is this only resolvable by a hard reset? Thanks and sorry for the long post. Any help would be appreciated.

Can you try booting into recovery mode? Although, I'm not sure if it does have it.

Viruses removal. First that will save you time. Does your tablet run hot. And does it lag? Which means is it slow ?
