Avast Android Free Samsung Keyboard Error

Hello, I am new here and after looking i have yet to see a Samsung Keyboard Error.
My 94 yr old fathers phone is a Samsung J7. I installed Avast as an anti-virus because his phone is acting weird and I have been able to trust reliability for years on PC application.
The scan provides me with an error. Im just trying to make sure this isn’t a key logger.
Detection Id is 155640a751d1e
I understand if its an outlier or false positive.
Certainly would be better if the Knowledge Base had a data base we can enter error numbers.
Thank you for any error and time.
